Descope SDK for Node.js

The Descope SDK for Node.js provides convenient access to the Descope user management and authentication API for a backend written in Node.js. You can read more on the Descope Website.

Requirements

The SDK supports Node version 14 and above.

Installing the SDK

Install the package with:

npm i --save @descope/node-sdk

Authentication Functions

Setup

Before you can use authentication functions listed below, you must initialize descopeClient to use all of the built-in SDK functions.

You'll need your Descope Project ID to create this, and you can find it on the project page in the Descope Console.

import DescopeClient from '@descope/node-sdk';

const descopeClient = DescopeClient({ projectId: 'my-project-ID' });

Once you've created a descopeClient, you can use that to work with the following functions:

1. OTP Authentication
2. Magic Link
3. Enchanted Link
4. OAuth
5. SSO/SAML
6. TOTP Authentication
7. Passwords
8. Session Validation
9. Roles & Permission Validation
10. Logging Out

Management Functions

Setup

Before you can use management functions listed below, you must initialize descopeClient.

If you wish to also use management functions, you will need to initialize a new version of your descopeClient, but this time with a ManagementKey as well as your Project ID. Create a management key in the Descope Console.

import DescopeClient from '@descope/node-sdk';

const descopeClient = DescopeClient({
  projectId: 'my-project-ID',
  managementKey: 'management-key',
});

Then, you can use that to work with the following functions:

1. Manage Tenants
2. Manage Users
3. Manage Access Keys
4. Manage SSO Setting
5. Manage Permissions
6. Manage Roles
7. Query SSO Groups
8. Manage Flows
9. Manage JWTs
10. Impersonate
11. Embedded Links
12. Audit
13. Manage Authz
14. Manage Project
15. Manage SSO applications

If you wish to run any of our code samples and play with them, check out our Code Examples section.

If you're performing end-to-end testing, check out the Utils for your end to end (e2e) tests and integration tests section. You will need to use the descopeClient you created under the setup of Management Functions.

Error Handling

Every async operation may fail. In case it does, there will be information regarding what happened on the response object. A typical case of error handling might look something like:

import { SdkResponse, descopeErrors } from '@descope/node-sdk';

// ...

try {
  const resp = await sdk.otp.signIn.email(loginId);
  if (resp.error) {
    switch (resp.error.errorCode) {
      case descopeErrors.userNotFound:
        // Handle specifically
        break;
      default:
      // Handle generally
      // `resp.error` will contain `errorCode`, `errorDescription` and sometimes `errorMessage` to
      // help understand what went wrong. See SdkResponse for more information.
    }
  }
} catch (e) {
  // Handle technical error
}

OTP Authentication

Send a user a one-time password (OTP) using your preferred delivery method (Email / SMS / Voice call / WhatsApp). An email address or phone number must be provided accordingly.

The user can either sign up, sign in or sign up or in

// Every user must have a login ID. All other user information is optional
const loginId = '[email protected]';
const user = {
  name: 'Desmond Copland',
  phone: '212-555-1234',
  email: loginId,
};
await descopeClient.otp.signUp['email'](loginId, user);

The user will receive a code using the selected delivery method. Verify that code using:

const jwtResponse = await descopeClient.otp.verify['email'](loginId, 'code');
// jwtResponse.data.sessionJwt
// jwtResponse.data.refreshJwt

The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation

Magic Link

Send a user a Magic Link using your preferred delivery method (email / SMS). The Magic Link will redirect the user to page where the its token needs to be verified. This redirection can be configured in code, or globally in the Descope Console

The user can either sign up, sign in or sign up or in

// If configured globally, the redirect URI is optional. If provided however, it will be used
// instead of any global configuration
const URI = 'http://myapp.com/verify-magic-link';
await descopeClient.magicLink.signUpOrIn['email']('[email protected]', URI);

To verify a magic link, your redirect page must call the validation function on the token (t) parameter (https://your-redirect-address.com/verify?t=<token>):

const jwtResponse = await descopeClient.magicLink.verify('token');
// jwtResponse.data.sessionJwt;
// jwtResponse.data.refreshJwt;

The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation

Enchanted Link

Using the Enchanted Link APIs enables users to sign in by clicking a link delivered to their email address. The email will include 3 different links, and the user will have to click the right one, based on the 2-digit number that is displayed when initiating the authentication process.

This method is similar to Magic Link but differs in two major ways:

• The user must choose the correct link out of the three, instead of having just one single link.
• This supports cross-device clicking, meaning the user can try to log in on one device, like a computer, while clicking the link on another device, for instance a mobile phone.

The Enchanted Link will redirect the user to page where the its token needs to be verified. This redirection can be configured in code per request, or set globally in the Descope Console.

The user can either sign up, sign in or sign up or in

// If configured globally, the redirect URI is optional. If provided however, it will be used
// instead of any global configuration.
const URI = 'http://myapp.com/verify-enchanted-link';
const enchantedLinkRes = await descopeClient.enchantedLink.signIn('[email protected]', URI);
enchantedLinkRes.data.linkId; // Should be displayed to the user so they can click the corresponding link in the email
enchantedLinkRes.data.pendingRef; // Used to poll for a valid session

After sending the link, you must poll to receive a valid session using the pendingRef from the previous step. A valid session will be returned only after the user clicks the right link.

// Poll for a certain number of tries / time frame. You can control the polling interval and time frame
// with the optional WaitForSessionConfig
const jwtResponse = await descopeClient.enchantedLink.waitForSession(
  enchantedLinkRes.data.pendingRef,
);
// jwtResponse.data.sessionJwt;
// jwtResponse.data.refreshJwt;

To verify an enchanted link, your redirect page must call the validation function on the token (t) parameter (https://your-redirect-address.com/verify?t=<token>). Once the token is verified, the session polling will receive a valid response.

try {
  await descopeClient.enchantedLink.verify('token');
  // token is invalid
} catch (error) {
  // token is valid
}

The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation

OAuth

Users can authenticate using their social logins, via the OAuth protocol. Configure your OAuth settings on the Descope console. To start an OAuth flow call:

// Choose an oauth provider out of the supported providers
// If configured globally, the return URL is optional. If provided however, it will be used
// instead of any global configuration.

const urlRes = await descopeClient.oauth.start['google'](redirectUrl);
urlRes.data.url; // Redirect the user to the returned URL to start the OAuth redirect chain

The user will authenticate with the authentication provider, and will be redirected back to the redirect URL, with an appended code HTTP URL parameter. Exchange it to validate the user:

const jwtResponse = await descopeClient.oauth.exchange('token');
// jwtResponse.data.sessionJwt;
// jwtResponse.data.refreshJwt;

The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation

SSO/SAML

Users can authenticate to a specific tenant using SAML or Single Sign On. Configure your SSO/SAML settings on the Descope console. To start a flow call:

// If configured globally, the return URL is optional. If provided however, it will be used
// instead of any global configuration.
const redirectUrl = 'https://my-app.com/handle-saml';
const urlRes = await descopeClient.saml.start('tenant'); // Choose which tenant to log into. An email can also be provided here and the domain will be extracted from it
urlRes.data.url; // Redirect the user to the given returned URL to start the SSO/SAML redirect chain

The user will authenticate with the authentication provider configured for that tenant, and will be redirected back to the redirect URL, with an appended code HTTP URL parameter. Exchange it to validate the user:

const jwtResponse = await descopeClient.saml.exchange('token');
// jwtResponse.data.sessionJwt;
// jwtResponse.data.refreshJwt;

The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation

TOTP Authentication

The user can authenticate using an authenticator app, such as Google Authenticator. Sign up like you would using any other authentication method. The sign up response will then contain a QR code image that can be displayed to the user to scan using their mobile device camera app, or the user can enter the key manually or click on the link provided by the provisioningURL.

Existing users can add TOTP using the update function.

// Every user must have a login ID. All other user information is optional
const loginId = '[email protected]';
const user = {
  name: 'Desmond Copland',
  phone: '212-555-1234',
  email: loginId,
};
const totpRes = await descopeClient.totp.signUp(loginId, user);
// Use one of the provided options to have the user add their credentials to the authenticator
totpRes.data.provisioningURL;
totpRes.data.image;
totpRes.data.key;

There are 3 different ways to allow the user to save their credentials in their authenticator app - either by clicking the provisioning URL, scanning the QR image or inserting the key manually. After that, signing in is done using the code the app produces.

const jwtResponse = await descopeClient.totp.verify(loginId, 'code');
// jwtResponse.data.sessionJwt;
// jwtResponse.data.refreshJwt;

The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation

Passwords

The user can also authenticate with a password, though it's recommended to prefer passwordless authentication methods if possible. Sign up requires the caller to provide a valid password that meets all the requirements configured for the password authentication method in the Descope console.

// Every user must have a loginId. All other user information is optional
const loginId = '[email protected]';
const password = 'qYlvi65KaX';
const user = {
  name: 'Desmond Copeland',
  email: loginId,
};
const jwtResponse = await descopeClient.password.signUp(loginId, password, user);
// jwtResponse.data.sessionJwt;
// jwtResponse.data.refreshJwt;

The user can later sign in using the same loginId and password.

const jwtResponse = await descopeClient.password.signIn(loginId, password);
// jwtResponse.data.sessionJwt;
// jwtResponse.data.refreshJwt;

The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation

In case the user needs to update their password, one of two methods are available: Resetting their password or replacing their password

Changing Passwords

NOTE: sendReset will only work if the user has a validated email address. Otherwise password reset prompts cannot be sent.

In the password authentication method in the Descope console, it is possible to define which alternative authentication method can be used in order to authenticate the user, in order to reset and update their password.

// Start the reset process by sending a password reset prompt. In this example we'll assume
// that magic link is configured as the reset method. The optional redirect URL is used in the
// same way as in regular magic link authentication.
const loginId = '[email protected]';
const redirectURL = 'https://myapp.com/password-reset';
const passwordResetResponse = await descopeClient.password.sendReset(loginId, redirectURL);

The magic link, in this case, must then be verified like any other magic link (see the magic link section for more details). However, after verifying the user, it is expected to allow them to provide a new password instead of the old one. Since the user is now authenticated, this is possible via:

// The refresh token is required to make sure the user is authenticated.
await descopeClient.password.update(loginId, newPassword, token);

update() can always be called when the user is authenticated and has a valid session.

Alternatively, it is also possible to replace an existing active password with a new one.

// Replaces the user's current password with a new one
const jwtResponse = await descopeClient.password.replace(loginId, oldPassword, newPassword);
// jwtResponse.data.sessionJwt;
// jwtResponse.data.refreshJwt;

Session Validation

Every secure request performed between your client and server needs to be validated. The client sends the session and refresh tokens with every request, and they are validated using one of the following:

// Validate the session. Will throw if expired
const authInfo = await descopeClient.validateSession('sessionToken');

// If validateSession throws an exception, you will need to refresh the session using
const authInfo = await descopeClient.refreshSession('refreshToken');

// Alternatively, you could combine the two and
// have the session validated and automatically refreshed when expired
const authInfo = await descopeClient.validateAndRefreshSession('sessionToken', 'refreshToken');

Choose the right session validation and refresh combination that suits your needs. Refreshed sessions return the same response as is returned when users first sign up / log in, containing the session and refresh tokens, as well as all of the JWT claims. Make sure to return the session token from the response to the client if tokens are validated directly.

Usually, the tokens can be passed in and out via HTTP headers or via a cookie. The implementation can defer according to your implementation. See our examples for a few examples.

If Roles & Permissions are used, validate them immediately after validating the session. See the next section for more information.

Session Validation Using Middleware

Alternatively, you can create a simple middleware function that internally uses the validateSession function. This middleware will automatically parse the cookies from the request. On failure, it will respond with 401 Unauthorized.

const authMiddleware = async (req: Request, res: Response, next: NextFunction) => {
  try {
    const cookies = parseCookies(req);
    const out = await clientAuth.auth.validateSession(
      cookies[DescopeClient.SessionTokenCookieName],
      cookies[DescopeClient.RefreshTokenCookieName],
    );
    if (out?.cookies) {
      res.set('Set-Cookie', out.cookies);
    }
    next();
  } catch (e) {
    res.status(401).json({
      error: 'Unauthorized!',
    });
  }
};

Roles & Permission Validation

When using Roles & Permission, it's important to validate the user has the required authorization immediately after making sure the session is valid. Taking the AuthenticationInfo received by the session validation, call the following functions:

For multi-tenant uses:

// You can validate specific permissions
const validTenantPermissions = descopeClient.validateTenantPermissions(authInfo, 'my-tenant-ID', [
  'Permission to validate',
]);
if (!validTenantPermissions) {
  // Deny access
}

// Or validate roles directly
const validTenantRoles = descopeClient.validateTenantRoles(authInfo, 'my-tenant-ID', [
  'Role to validate',
]);
if (!validTenantRoles) {
  // Deny access
}

// Or get the matched roles/permissions
const matchedTenantRoles = descopeClient.getMatchedTenantRoles(authInfo, 'my-tenant-ID', [
  'Role to validate',
  'Another role to validate',
]);

const matchedTenantPermissions = descopeClient.getMatchedTenantPermissions(
  authInfo,
  'my-tenant-ID',
  ['Permission to validate', 'Another permission to validate'],
);

When not using tenants use:

// You can validate specific permissions
const validPermissions = descopeClient.validatePermissions(authInfo, ['Permission to validate']);
if (!validPermissions) {
  // Deny access
}

// Or validate roles directly
const validRoles = descopeClient.validateRoles(authInfo, ['Role to validate']);
if (!validRoles) {
  // Deny access
}

// Or get the matched roles/permissions
const matchedRoles = descopeClient.getMatchedRoles(authInfo, [
  'Role to validate',
  'Another role to validate',
]);

const matchedPermissions = descopeClient.getMatchedPermissions(authInfo, [
  'Permission to validate',
  'Another permission to validate',
]);

Logging Out

You can log out a user from an active session by providing their refreshToken for that session. After calling this function, you must invalidate or remove any cookies you have created.

await descopeClient.logout(refreshToken);

It is also possible to sign the user out of all the devices they are currently signed-in with. Calling logoutAll will invalidate all user's refresh tokens. After calling this function, you must invalidate or remove any cookies you have created.

await descopeClient.logoutAll(refreshToken);

Management Functions

It is very common for some form of management or automation to be required. These can be performed using the management functions. Please note that these actions are more sensitive as they are administrative in nature. Please use responsibly.

Setup

To use the management API you'll need a Management Key along with your Project ID. Create one in the Descope Console.

import DescopeClient from '@descope/node-sdk';

const descopeClient = DescopeClient({
  projectId: 'my-project-ID',
  managementKey: 'management-key',
});

Manage Tenants

You can create, update, delete or load tenants, as well as read and update tenant settings:

// The self provisioning domains or optional. If given they'll be used to associate
// Users logging in to this tenant
await descopeClient.management.tenant.create('My Tenant', ['domain.com'], {
  customAttributeName: 'val',
});

// You can optionally set your own ID when creating a tenant
await descopeClient.management.tenant.createWithId('my-custom-id', 'My Tenant', ['domain.com'], {
  customAttributeName: 'val',
});

// Update will override all fields as is. Use carefully.
await descopeClient.management.tenant.update(
  'my-custom-id',
  'My Tenant',
  ['domain.com', 'another-domain.com'],
  { customAttributeName: 'val' },
);

// Tenant deletion cannot be undone. Use carefully.
await descopeClient.management.tenant.delete('my-custom-id');

// Load tenant by id
const tenant = await descopeClient.management.tenant.load('my-custom-id');

// Load all tenants
const tenantsRes = await descopeClient.management.tenant.loadAll();
tenantsRes.data.forEach((tenant) => {
  // do something
});

// Search all tenants according to various parameters
const searchRes = await descopeClient.management.tenant.searchAll(['id']);
searchRes.data.forEach((tenant) => {
  // do something
});

// Load tenant settings by id
const tenantSettings = await descopeClient.management.tenant.getSettings('my-tenant-id');

// Update will override all fields as is. Use carefully.
await descopeClient.management.tenant.configureSettings('my-tenant-id', {
  domains: ['domain1.com'],
  selfProvisioningDomains: ['domain1.com'],
  sessionSettingsEnabled: true,
  refreshTokenExpiration: 12,
  refreshTokenExpirationUnit: 'days',
  sessionTokenExpiration: 10,
  sessionTokenExpirationUnit: 'minutes',
  enableInactivity: true,
  JITDisabled: false,
  InactivityTime: 10,
  InactivityTimeUnit: 'minutes',
});

Manage Password

You can read and update any tenant password settings and policy:

// Load tenant password settings by id
const passwordSettings = await descopeClient.management.password.getSettings('my-tenant-id');

// Update will override all fields as is. Use carefully.
await descopeClient.management.password.configureSettings('my-tenant-id', {
  enabled: true,
  minLength: 8,
  expiration: true,
  expirationWeeks: 4,
  lock: true,
  lockAttempts: 5,
  reuse: true,
  reuseAmount: 6,
  lowercase: true,
  uppercase: false,
  number: true,
  nonAlphaNumeric: false,
});

Manage SSO applications

You can create, update, delete or load SSO applications:

// Create OIDC sso application
await descopeClient.management.ssoApplication.createOidcApplication({
  name: 'My OIDC app name',
  loginPageUrl: 'http://dummy.com/login',
});

// Create SAML sso application
await descopeClient.management.ssoApplication.createSamlApplication({
  name: 'My SAML app name',
  loginPageUrl: 'http://dummy.com/login',
  useMetadataInfo: true,
  metadataUrl: 'http://dummy.com/metadata',
});

// Update OIDC sso application.
// Update will override all fields as is. Use carefully.
await descopeClient.management.ssoApplication.updateOidcApplication({
  id: 'my-app-id',
  name: 'My OIDC app name',
  loginPageUrl: 'http://dummy.com/login',
});

// Update SAML sso application.
// Update will override all fields as is. Use carefully.
await descopeClient.management.ssoApplication.updateSamlApplication({
  id: 'my-app-id',
  name: 'My SAML app name',
  loginPageUrl: 'http://dummy.com/login',
  enabled: true,
  useMetadataInfo: false,
  entityId: 'entity1234',
  aceUrl: 'http://dummy.com/acs',
  certificate: 'certificate',
});

// Tenant deletion cannot be undone. Use carefully.
await descopeClient.management.ssoApplication.delete('my-app-id');

// Load sso application by id
const app = await descopeClient.management.ssoApplication.load('my-app-id');

// Load all sso applications
const appsRes = await descopeClient.management.ssoApplication.loadAll();
appsRes.data.forEach((app) => {
  // do something
});

Manage Users

You can create, update, delete or load users, as well as search according to filters:

// A user must have a login ID, other fields are optional.
// Roles should be set directly if no tenants exist, otherwise set
// on a per-tenant basis.
await descopeClient.management.user.create('[email protected]', {
  email: '[email protected]',
  displayName: 'Desmond Copeland',
  userTenants: [{ tenantId: 'tenant-ID1', roleNames: ['role-name1'] }],
});

// Alternatively, a user can be created and invited via an email / text message.
// Make sure to configure the invite URL in the Descope console prior to using this function,
// and that an email address / phone number is provided in the information.
await descopeClient.management.user.invite('[email protected]', {
  email: '[email protected]',
  displayName: 'Desmond Copeland',
  userTenants: [{ tenantId: 'tenant-ID1', roleNames: ['role-name1'] }],
  // You can inject custom data into the template.
  // Note that you first need to configure custom template in Descope Console
  // For example: configure {{options_k1}} in the custom template, and pass { k1: 'v1' } as templateOptions
  templateOptions: { k1: 'v1', k2: 'v2' },
});

// You can invite batch of users via an email / text message.
// Make sure to configure the invite URL in the Descope console prior to using this function,
// and that an email address / phone number is provided in the information. You can also set
// a cleartext password or import a prehashed one from another service.
await descopeClient.management.user.inviteBatch(
  [
    {
      loginId: '[email protected]',
      email: '[email protected]',
      phone: '+123456789123',
      displayName: 'Desmond Copeland',
      userTenants: [{ tenantId: 'tenant-ID1', roleNames: ['role-name1'] }],
      hashedPassword: {
        bcrypt: {
          hash: '$2a$...',
        },
      },
    },
  ],
  '<invite_url>',
  true,
  false,
);

// Update will override all fields as is. Use carefully.
await descopeClient.management.user.update('[email protected]', {
  email: '[email protected]',
  displayName: 'Desmond Copeland',
  userTenants: [{ tenantId: 'tenant-ID1', roleNames: ['role-name1'] }],
});

// Update explicit data for a user rather than overriding all fields
await descopeClient.management.user.updatePhone('[email protected]', '+18005551234', true);
await descopeClient.management.user.updateLoginId('[email protected]', '[email protected]');
await descopeClient.management.user.removeTenantRoles(
  '[email protected]',
  'tenant-ID1',
  'role-name2',
);

// User deletion cannot be undone. Use carefully.
await descopeClient.management.user.delete('[email protected]');

// Load specific user
const userRes = await descopeClient.management.user.load('[email protected]');

// If needed, users can be loaded using the user ID as well
const userRes = await descopeClient.management.user.loadByUserId('<user-ID>');

// Search all users, optionally according to tenant and/or role filter
// Results can be paginated using the limit and page parameters
const usersRes = await descopeClient.management.user.search({ tenantIds: ['tenant-ID'] });
usersRes.data.forEach((user) => {
  // do something
});

await descopeClient.management.user.logoutUser('my-custom-id');

await descopeClient.management.user.logoutUserByUserId('<user-ID>');

// Get users' authentication history
const userIds = ['user-id-1', 'user-id-2'];
const usersHistoryRes = await descopeClient.management.user.history(userIds);
usersHistoryRes.forEach((userHistory) => {
  // do something
});

Set or Expire User Password

You can set a new active password for a user that they can sign in with. You can also set a temporary password that they user will be forced to change on the next login. For a user that already has an active password, you can expire their current password, effectively requiring them to change it on the next login.

// Set a user's temporary password
await descopeClient.management.user.setTemporaryPassword('<login-ID>', '<some-password>');

// Set a user's password
await descopeClient.management.user.setActivePassword('<login-ID>', '<some-password>');

// Or alternatively, expire a user password
await descopeClient.management.user.expirePassword('<login-ID>');

Manage Project

You can update project name, as well as to clone the current project to a new one:

// Update will override all fields as is. Use carefully.
await descopeClient.management.project.updateName('new-project-name');

// Clone the current project to a new one
// Note that this action is supported only with a pro license or above.
const cloneRes = await descopeClient.management.project.clone('new-project-name');

You can manage your project's settings and configurations by exporting your project's environment. You can also import previously exported data into the same project or a different one.

// Exports the current state of the project
const files = await descopeClient.management.project.export();

// Import the previously exported data into the current project
await descopeClient.management.project.import(files);

Manage Access Keys

You can create, update, delete or load access keys, as well as search according to filters:

// An access key must have a name and expiration, other fields are optional.
// Roles should be set directly if no tenants exist, otherwise set
// on a per-tenant basis.
// If userId is supplied, then authorization will be ignored, and the access key will be bound to the user's authorization.
// If customClaims is supplied, then those claims will be present in the JWT returned by calls to ExchangeAccessKey.
await descopeClient.management.accessKey.create(
  'key-name',
  123456789, // expiration time
  null,
  [{ tenantId: 'tenant-ID1', roleNames: ['role-name1'] }],
);

// Load specific user
const accessKeyRes = await descopeClient.management.accessKey.load('key-id');

// Search all users, optionally according to tenant and/or role filter
const accessKeysRes = await descopeClient.management.accessKey.searchAll(['tenant-ID']);
accessKeysRes.data.forEach((accessKey) => {
  // do something
});

// Update will override all fields as is. Use carefully.
await descopeClient.management.accessKey.update('key-id', 'new-key-name');

// Access keys can be deactivated to prevent usage. This can be undone using "activate".
await descopeClient.management.accessKey.deactivate('key-id');

// Disabled access keys can be activated once again.
await descopeClient.management.accessKey.activate('key-id');

// Access key deletion cannot be undone. Use carefully.
await descopeClient.management.accessKey.delete('key-id');

Manage SSO Setting

You can manage SSO settings and map SSO group roles and user attributes.

// You can get SSO settings for a specific tenant ID
const ssoSettings = await descopeClient.management.sso.loadSettings("tenant-id")

// You can configure SSO settings manually by setting the required fields directly
const tenantId = 'tenant-id' // Which tenant this configuration is for
const idpURL = 'https://idp.com'
const entityID = 'my-idp-entity-id'
const idpCert = '<your-cert-here>'
const redirectURL = 'https://my-app.com/handle-sso' // Global redirect URL for SSO/SAML
const domains = ['tenant-users.com'] // Users authentication with this domain will be logged in to this tenant
await descopeClient.management.sso.configureSAMLSettings(tenantID, {idpURL, entityID, idpCert}, redirectURL, domains)

// Alternatively, configure using an SSO metadata URL
await descopeClient.management.sso.configureSAMLByMetadata(tenantID, {idpMetadataUrl: 'https://idp.com/my-idp-metadata'}, redirectURL, domains)

// In case SSO is configured to work with OIDC use the following
const name = 'some-name';
const clientId = 'client id of OIDC';
const clientSecret =  'client secret';
await descopeClient.management.sso.configureOIDCSettings(tenantID, {name, clientId, clientSecret, redirectUrl}, domains)

// Map IDP groups to Descope roles, or map user attributes.
// This function overrides any previous mapping (even when empty). Use carefully.
await descopeClient.management.sso.configureMapping(
   tenantId,
   [{ groups: ['IDP_ADMIN'], roleName: 'Tenant Admin'}]
   { name: 'IDP_NAME', phoneNumber: 'IDP_PHONE'},
)

Note: Certificates should have a similar structure to:

-----BEGIN CERTIFICATE-----
Certifcate contents
-----END CERTIFICATE-----

// You can delete SSO settings for a specific tenant ID await descopeClient.management.sso.deleteSettings("tenant-id")

Manage Permissions

You can create, update, delete or load permissions:

// You can optionally set a description for a permission.
const name = 'My Permission';
let description = 'Optional description to briefly explain what this permission allows.';
await descopeClient.management.permission.create(name, description);

// Update will override all fields as is. Use carefully.
const newName = 'My Updated Permission';
description = 'A revised description';
await descopeClient.management.permission.update(name, newName, description);

// Permission deletion cannot be undone. Use carefully.
await descopeClient.management.permission.delete(newName);

// Load all permissions
const permissionsRes = await descopeClient.management.permission.loadAll();
permissionsRes.data.forEach((permission) => {
  // do something
});

Manage Roles

You can create, update, delete or load roles:

// You can optionally set a description and associated permission for a roles.
// The optional `tenantId` will scope this role for a specific tenant. If left empty, the role will be available to all tenants.
const name = 'My Role';
const tenantId = '<tenant id>';
let description = 'Optional description to briefly explain what this role allows.';
const permissionNames = ['My Updated Permission'];
descopeClient.management.role.create(name, description, permissionNames, tenantId);

// Update will override all fields as is. Use carefully.
const newName = 'My Updated Role';
description = 'A revised description';
permissionNames.push('Another Permission');
descopeClient.management.role.update(name, newName, description, permissionNames, tenantId);

// Role deletion cannot be undone. Use carefully.
descopeClient.management.role.delete(newName, tenantId);

// Load all roles
const rolesRes = await descopeClient.management.role.loadAll();
rolesRes.data.forEach((role) => {
  // do something
});

// Search roles
const rolesRes = await descopeClient.management.role.search({
  tenantIds: ['t1', 't2'],
  roleNames: ['role1'],
});
rolesRes.data.forEach((role) => {
  // do something
});

Query SSO Groups

You can query SSO groups:

// Load all groups for a given tenant id
const groupsRes = descopeClient.management.group.loadAllGroups('tenant-id');

// Load all groups for the given user IDs (can be found in the user's JWT)
const groupsRes = descopeClient.management.group.loadAllGroupsForMember('tenant-id', [
  'user-id-1',
  'user-id-2',
]);

// Load all groups for the given user login IDs (used for sign-in)
const groupsRes = descopeClient.management.group.loadAllGroupsForMember(
  'tenant-id',
  [],
  ['login-id-1', 'login-id-2'],
);

// Load all group's members by the given group id
const groupsRes = descopeClient.management.group.loadAllGroupMembers('tenant-id', 'group-id');

groupsRes.data.forEach((group) => {
  // do something
});

Manage Flows

You can list your flows and also import and export flows and screens, or the project theme:

// List all project flows
const res = await descopeClient.management.flow.list();
console.log('found total flows', res.total);
res.flows.forEach((flowMetadata) => {
  // do something
});

// Delete flows by ids
await descopeClient.management.flow.delete(['flow-1', 'flow-2']);

// Export the flow and it's matching screens based on the given id
const res = await descopeClient.management.flow.export('sign-up');
console.log('found flow', res.data.flow);
res.data.screens.forEach((screen) => {
  // do something
});

// Import the given flow and screens as the given id
const { flow, screens } = res.data;
const updatedRes = descopeClient.management.flow.import('sign-up', flow, screens);
console.log('updated flow', updatedRes.data.flow);
updatedRes.data.screens.forEach((screen) => {
  // do something
});

// Export the current theme of the project
const res = descopeClient.management.theme.export();
console.log(res.data.theme);

// Import the given theme to the project
const updatedRes = descopeClient.management.theme.import(theme);
console.log(updatedRes.data.theme);

Manage JWTs

You can add custom claims to a valid JWT.

const updatedJWTRes = await descopeClient.management.jwt.update('original-jwt', {
  customKey1: 'custom-value1',
  customKey2: 'custom-value2',
});

Impersonate

You can impersonate to another user The impersonator user must have the impersonation permission in order for this request to work. The response would be a refresh JWT of the impersonated user

const updatedJWTRes = await descopeClient.management.jwt.impersonate(
  'impersonator-id',
  'login-id',
  true,
);

Note 1: The generate code/link functions, work only for test users, will not work for regular users. Note 2: In case of testing sign-in / sign-up operations with test users, need to make sure to generate the code prior calling the sign-in / sign-up operations.

Embedded Links

Embedded links can be created to directly receive a verifiable token without sending it. This token can then be verified using the magic link 'verify' function, either directly or through a flow.

const { token } = await descopeClient.management.user.generateEmbeddedLink('[email protected]', {
  key1: 'value1',
});

Audit

You can perform an audit search for either specific values or full-text across the fields. Audit search is limited to the last 30 days.

// Full text search on the last 10 days
const audits = await descopeClient.management.audit.search({
  from: Date.now() - 10 * 24 * 60 * 60 * 1000,
  text: 'some-text',
});
console.log(audits);

// Search successful logins in the last 30 days
const audits = await descopeClient.management.audit.search({ actions: ['LoginSucceed'] });
console.log(audits);

You can also create audit event with data

await descopeClient.management.audit.createEvent({
  action: 'pencil.created',
  type: 'info', // info/warn/error
  actorId: 'UXXX',
  tenantId: 'tenant-id',
  data: {
    some: 'data',
  },
});

Manage Authz

Descope support full relation based access control (ReBAC) using a zanzibar like schema and operations. A schema is comprized of namespaces (entities like documents, folders, orgs, etc.) and each namespace has relation definitions to define relations. Each relation definition can be simple (either you have it or not) or complex (union of nodes).

A simple example for a file system like schema would be:

# Example schema for the authz tests
name: Files
namespaces:
  - name: org
    relationDefinitions:
      - name: parent
      - name: member
        complexDefinition:
          nType: union
          children:
            - nType: child

                targetRelationDefinition: editor
                targetRelationDefinitionNamespace: doc

Descope SDK allows you to fully manage the schema and relations as well as perform simple (and not so simple) checks regarding the existence of relations.

// Load the existing schema
const s = await descopeClient.management.authz.loadSchema();
console.log(s);

// Save schema and make sure to remove all namespaces not listed
await descopeClient.management.authz.saveSchema(s, true);

// Create a relation between a resource and user
await descopeClient.management.authz.createRelations([
  {
    resource: 'some-doc',
    relationDefinition: 'owner',
    namespace: 'doc',
    target: 'u1',
  },
  {
    resource: 'some-doc',
    relationDefinition: 'editor',
    namespace: 'doc',
    target: 'u2',
  },
]);

// Check if target has the relevant relation
// The answer should be true because an owner is also a viewer
const q = await descopeClient.management.authz.hasRelations([
  {
    resource: 'some-doc',
    relationDefinition: 'viewer',
    namespace: 'doc',
    target: 'u1',
  },
]);

Utils for your end to end (e2e) tests and integration tests

To ease your e2e tests, we exposed dedicated management methods, that way, you don't need to use 3rd party messaging services in order to receive sign-in/up Email, SMS, Voice call or WhatsApp, and avoid the need of parsing the code and token from them.

// User for test can be created, this user will be able to generate code/link without
// the need of 3rd party messaging services.
// Test user must have a loginId, other fields are optional.
// Roles should be set directly if no tenants exist, otherwise set
// on a per-tenant basis.
await descopeClient.management.user.createTestUser('[email protected]', {
  email: '[email protected]',
  displayName: 'Desmond Copeland',
  userTenants: [{ tenantId: 'tenant-ID1', roleNames: ['role-name1'] }],
});

// Now test user got created, and this user will be available until you delete it,
// you can use any management operation for test user CRUD.
// You can also delete all test users.
await descopeClient.management.user.deleteAllTestUsers();

// OTP code can be generated for test user, for example:
const { code } = await descopeClient.management.user.generateOTPForTestUser(
  'sms', // you can use also 'email', 'whatsapp', 'voice'
  '[email protected]',
);
// Now you can verify the code is valid (using descopeClient.auth.*.verify for example)
// LoginOptions can be provided to set custom claims to the generated jwt.

// Same as OTP, magic link can be generated for test user, for example:
const { link } = await descopeClient.management.user.generateMagicLinkForTestUser(
  'email',
  '[email protected]',
  '',
);

// Enchanted link can be generated for test user, for example:
const { link, pendingRef } = await descopeClient.management.user.generateEnchantedLinkForTestUser(
  '[email protected]',
  '',
);

Code Examples

You can find various usage examples in the examples folder.

Setup

To run the examples, set your Project ID by setting the DESCOPE_PROJECT_ID env var or directly in the sample code. Find your Project ID in the Descope console.

export DESCOPE_PROJECT_ID=<ProjectID>

Run an example

Run the following commands in the root of the project to build and run the examples with a local build of the SDK.

1. Run this to start the ES6 typescript module example

   npm i && \
   npm run build && \
   cd examples/es6 && \
   npm i && \
   npm run generateCerts && \
   npm start

2. Run this to start the commonjs example

   npm i && \
   npm run build && \
   cd examples/commonjs && \
   npm i && \
   npm run generateCerts && \
   npm start

Providing Custom Public Key

By default, the SDK will download the public key from Descope's servers. You can also provide your own public key. This is useful when the server you are running the SDK on does not have access to the internet.

You can find your public key in the https://api.descope.com/v2/keys/<project-id> endpoint. For further information, please see the Descope Documentation and API reference page.

To provide your own public key, you can do so by providing the publicKey option when initializing the SDK:

import DescopeClient from '@descope/node-sdk';

const descopeClient = DescopeClient({
  projectId: 'my-project-ID',
  publicKey: '{"alg":"RS256", ... }',
});

// The public key will be used when validating jwt
const sessionJWt = '<session-jwt>';
await descopeClient.validateJwt(sessionJWt);
