Help and Feedback

Supported Node Versions

This library supports the following Node versions:

Node 10+

If you have specific version demands for your projects, feel free to contact us.

Stark Infra API documentation

Feel free to take a look at our API docs.

Versioning

This project adheres to the following versioning pattern:

Given a version number MAJOR.MINOR.PATCH, increment:

MAJOR version when the API version is incremented. This may include backwards incompatible changes;
MINOR version when breaking changes are introduced OR new functionalities are added in a backwards compatible manner;
PATCH version when backwards compatible bug fixes are implemented.

Setup

1. Install our SDK

1.1 To install the package with npm, run:

npm install starkinfra

2. Create your Private and Public Keys

We use ECDSA. That means you need to generate a secp256k1 private key to sign your requests to our API, and register your public key with us, so we can validate those requests.

You can use one of the following methods:

2.1. Check out the options in our tutorial.

2.2. Use our SDK:

const starkinfra = require('starkinfra');

let privateKey, publicKey;

[privateKey, publicKey] = starkinfra.key.create();

// or, to also save .pem files in a specific path
[privateKey, publicKey] = starkinfra.key.create('file/keys/');

NOTE: When you are creating new credentials, it is recommended that you create the keys inside the infrastructure that will use it, in order to avoid risky internet transmissions of your private-key. Then you can export the public-key alone to the computer where it will be used in the new Project creation.

3. Register your user credentials

You can interact directly with our API using two types of users: Projects and Organizations.

Projects are workspace-specific users, that is, they are bound to the workspaces they are created in. One workspace can have multiple Projects.
Organizations are general users that control your entire organization. They can control all your Workspaces and even create new ones. The Organization is bound to your company's tax ID only. Since this user is unique in your entire organization, only one credential can be linked to it.

3.1. To create a Project in Sandbox:

3.1.1. Log into StarkInfra Sandbox

3.1.2. Go to Menu > Integrations

3.1.3. Click on the 'New Project' button

3.1.4. Create a Project: Give it a name and upload the public key you created in section 2

3.1.5. After creating the Project, get its Project ID

3.1.6. Use the Project ID and private key to create the object below:

const starkinfra = require('starkinfra');

// Get your private key from an environment variable or an encrypted database.
// This is only an example of a private key content. You should use your own key.
let privateKeyContent = `
-----BEGIN EC PARAMETERS-----
BgUrgQQACg==
-----END EC PARAMETERS-----
-----BEGIN EC PRIVATE KEY-----
MHQCAQEEIMCwW74H6egQkTiz87WDvLNm7fK/cA+ctA2vg/bbHx3woAcGBSuBBAAK
oUQDQgAE0iaeEHEgr3oTbCfh8U2L+r7zoaeOX964xaAnND5jATGpD/tHec6Oe9U1
IF16ZoTVt1FzZ8WkYQ3XomRD4HS13A==
-----END EC PRIVATE KEY-----
`;

let project = new starkinfra.Project({
    environment: 'sandbox',
    id: '5656565656565656',
    privateKey: privateKeyContent
});

3.2. To create Organization credentials in Sandbox:

3.2.1. Log into Starkinfra Sandbox

3.2.2. Go to Menu > Integrations

3.2.3. Click on the 'Organization public key' button

3.2.4. Upload the public key you created in section 2 (only a legal representative of the organization can upload the public key)

3.2.5. Click on your profile picture and then on the 'Organization' menu to get the Organization ID

3.2.6. Use the Organization ID and private key to create the object below:

const starkinfra = require('starkinfra');

//  Get your private key from an environment variable or an encrypted database.
//  This is only an example of a private key content. You should use your own key.
let privateKeyContent = `
-----BEGIN EC PARAMETERS-----
BgUrgQQACg==
-----END EC PARAMETERS-----
-----BEGIN EC PRIVATE KEY-----
MHQCAQEEIMCwW74H6egQkTiz87WDvLNm7fK/cA+ctA2vg/bbHx3woAcGBSuBBAAK
oUQDQgAE0iaeEHEgr3oTbCfh8U2L+r7zoaeOX964xaAnND5jATGpD/tHec6Oe9U1
IF16ZoTVt1FzZ8WkYQ3XomRD4HS13A==
-----END EC PRIVATE KEY-----
`;

let organization = new starkinfra.Organization({
    id: '5656565656565656',
    privateKey: privateKeyContent,
    environment: 'sandbox',
    workspaceId: null // You only need to set the workspaceId when you are operating a specific workspaceId
});


// To dynamically use your organization credentials in a specific workspaceId,
// you can use the organization.replace() method:
(async() => {
    let balance = await starkinfra.issuingBalance.get({
        user: starkinfra.organization.replace(organization, '4848484848484848')
    });
    console.log(balance);
})();

NOTE 1: Never hard-code your private key. Get it from an environment variable or an encrypted database.

NOTE 2: We support 'sandbox' and 'production' as environments.

NOTE 3: The credentials you registered in sandbox do not exist in production and vice versa.

4. Setting up the user

There are three kinds of users that can access our API: Organization, Project, and Member.

Project and Organization are designed for integrations and are the ones meant for our SDKs.
Member is the one you use when you log into our webpage with your e-mail.

There are two ways to inform the user to the SDK:

4.1 Passing the user as an argument in all functions:

const starkinfra = require('starkinfra');
(async() => {
    let balance = await starkinfra.issuingBalance.get({user: project}); // or organization
})();

4.2 Set it as a default user in the SDK:

const starkinfra = require('starkinfra');

starkinfra.user = project; // or organization

(async() => {
    let balance = await starkinfra.issuingBalance.get();
})();

Just select the way of passing the user that is more convenient to you. On all following examples, we will assume a default user has been set.

5. Setting up the error language

The error language can also be set in the same way as the default user:

const starkinfra = require('starkinfra');

starkinfra.language = 'en-US';

Language options are 'en-US' for English and 'pt-BR' for Brazilian Portuguese. English is the default.

Resource listing and manual pagination

Almost all SDK resources provide a query and a page function.

The query function provides a straightforward way to efficiently iterate through all results that match the filters you inform, seamlessly retrieving the next batch of elements from the API only when you reach the end of the current batch. If you are not worried about data volume or processing time, this is the way to go.

const starkinfra = require('starkinfra');

(async() => {
    let transactions = await starkinfra.transaction.query({
        after: '2020-01-01',
        before: '2020-03-01'
    });
  
    for await (let transaction of transactions) {
        console.log(transaction);
    }
})();

The page function gives you full control over the API pagination. With each function call, you receive up to 100 results and the cursor to retrieve the next batch of elements. This allows you to stop your queries and pick up from where you left off whenever it is convenient. When there are no more elements to be retrieved, the returned cursor will be null.

const starkinfra = require('starkinfra');

(async() => {
    let cursor = null;
    let page = null;
    while (true) {
        [page, cursor] = await starkinfra.transaction.page({ limit: 5, cursor: cursor });
        for (let transaction of page) {
            console.log(transaction);
        }
        if (cursor == null) {
            break;
        }
    }
})();

To simplify the following SDK examples, we will only use the query function, but feel free to use page instead.

Testing in Sandbox

Your initial balance is zero. For many operations in Stark Infra, you'll need funds in your account, which can be added to your balance by creating a starkbank.Invoice.

In the Sandbox environment, most of the created starkbank.Invoices will be automatically paid, so there's nothing else you need to do to add funds to your account. Just create a few starkbank.Invoices and wait around a bit.

In Production, you (or one of your clients) will need to actually pay this Pix Request for the value to be credited to your account.

Usage

Here are a few examples on how to use the SDK. If you have any doubts, use the built-in help() function to get more info on the desired functionality (for example: help(starkinfra.issuinginvoice.create))

Issuing

Query IssuingProducts

To take a look at the sub-issuer card products available to you, just run the following:

await (async() => {
    let products = await starkinfra.issuingProduct.query();

    for await (let product of products) {
        console.log(product);
    }
})();

This will tell which card products and card number prefixes you have at your disposal.

Create IssuingHolders

You can create cardholders to which your cards will be bound. They support spending rules that will apply to all underlying cards.

await (async() => {
    let holders = await starkinfra.issuingHolder.create([
        new starkinfra.IssuingHolder({
            'name': 'Iron Bank S.A.',
            'taxId': '012.345.678-90',
            'externalId': '1234',
            'tags': ['Traveler Employee'],
            'rules': [
                new starkinfra.IssuingRule({
                    'name': 'General USD',
                    'interval': 'day',
                    'amount': 100000,
                    'currencyCode': 'USD',
                })
            ]
        })
    ]);

    for await (let holder of holders) {
        console.log(holder);
    }
})();

Note: Instead of using IssuingHolder objects, you can also pass each element in dictionary format

Query IssuingHolders

You can query multiple holders according to filters.

await (async() => {
    let holders = await starkinfra.issuingHolder.query();
  
    for await (let holder of holders) {
        console.log(holder);
    }
})();

})();

Query IssuingHolder logs

You can query holder logs to better understand holder life cycles.

await (async() => {
    let logs = await starkinfra.issuingHolder.log.query({'limit': 50});

    }
})();

Get an IssuingHolder log

You can also get a specific log by its id.

            'holderTaxId': '012.345.678-90',
            'holderExternalId': '1234',
            'rules': [
                new starkinfra.IssuingRule({
                    'name': 'general',
                    'interval': 'week',
                    'amount': 50000,
                    'currencyCode': 'USD',
                })
            ]

})();

Process Token authorizations

It's easy to process token authorizations delivered to your endpoint. Remember to pass the signature header so the SDK can make sure it's StarkInfra that sent you the event. If you do not approve or decline the authorization within 2 seconds, the authorization will be denied.

const starkinfra = require('starkinfra');
const express = require('express')
const app = express()

app.use(express.raw({type: '*/*'}));

const port = 3000
app.post('/', async (req, res) => {
    try {
        let authorization = await starkinfra.issuingToken.parse({
            content: req.body.toString(),
            signature: req.headers['digital-signature']
        });
        res.send(
            starkinfra.issuingToken.responseAuthorization( // this optional method just helps you build the response JSON
                status: 'accepted',
                activationMethods: [
                    {
                        'type': 'app',
                        'value': 'com.subissuer.android'
                    },
                    {
                        'type': 'text',
                        'value': '** *****-5678'
                    }

                tags=['token', 'user/1234']
            )
        );

        // or

        res.send(
            starkinfra.issuingToken.responseAuthorization(
                status: 'denied',
                reason: 'other'

        res.status(400).end()
    }
})
app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`))

Process Token activations

It's easy to process token activation notifications delivered to your endpoint. Remember to pass the signature header so the SDK can make sure it's Stark Infra that sent you the event.

const starkinfra = require('starkinfra');
const express = require('express')
const app = express()

app.use(express.raw({type: '*/*'}));

const port = 3000
app.post('/', async (req, res) => {
    try {
        let authorization = await starkinfra.issuingToken.parse({
            content: req.body.toString(),
            signature: req.headers['digital-signature']
        });
    }
    catch (err) {
        console.log(err)
        res.status(400).end()
    }
})
app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`))

After that, you may generate the activation code and send it to the cardholder. The cardholder enters the received code in the wallet app. We'll receive and send it to tokenAuthorizationUrl for your validation. Completing the provisioning process.

const starkinfra = require('starkinfra');
const express = require('express')
const app = express()

app.use(express.raw({type: '*/*'}));

    try {
        res.send(
            starkinfra.issuingToken.responseActivation( // this optional method just helps you build the response JSON
                status: 'approved',
                tags: ['token', 'user/1234']
            )
        );

        // or

        res.send(
            starkinfra.issuingToken.responseActivation(

    console.log(brcode);
})();

Create DynamicBrcodes

BR codes store information represented by Pix QR Codes, which are used to send or receive Pix transactions in a convenient way. DynamicBrcodes represent charges with information that can change at any time, since all data needed for the payment is requested dynamically to an URL stored in the BR Code. Stark Infra will receive the GET request and forward it to your registered endpoint with a GET request containing the UUID of the BR code for identification.

const starkinfra = require('starkinfra')

(async() => {
    let brcodes = await starkinfra.dynamicBrcode.create([
        new starkinfra.DynamicBrcode({

    console.log(brcode);
})();

Verify a DynamicBrcode read

When a DynamicBrcode is read by your user, a GET request will be made to the your regitered URL to retrieve additional information needed to complete the transaction. Use this method to verify the authenticity of a GET request received at your registered endpoint. If the provided digital signature does not check out with the StarkInfra public key, a starkinfra.error.InvalidSignatureError will be raised.

const starkinfra = require('starkinfra');
const express = require('express')
const app = express()

app.use(express.raw({type: '*/*'}));

const port = 3000
app.get('/', async (req, res) => {
    let uuid = await starkinfra.dynamicBrcode.verify({
        uuid: getUuid(req.url), // you should implement this method to extract the uuid from the request's URL
        signature: req.headers["Digital-Signature"],
    });
})
app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`));

Answer to a Due DynamicBrcode read

When a Due DynamicBrcode is read by your user, a GET request containing the BR code UUID will be made to your registered URL to retrieve additional information needed to complete the transaction.

The GET request must be answered in the following format within 5 seconds and with an HTTP status code 200.

Lending

If you want to establish a lending operation, you can use Stark Infra to create a CCB contract. This will enable your business to lend money without requiring a banking license, as long as you use a Credit Fund or Securitization company.

The required steps to initiate the operation are:

Have funds in your Credit Fund or Securitization account
Request the creation of an Identity Check for the credit receiver (make sure you have their documents and express authorization)
(Optional) Create a Credit Simulation with the desired installment plan to display information for the credit receiver
Create a Credit Note with the desired installment plan

Create CreditNotes

You can create a Credit Note to generate a CCB contract:

const starkinfra = require('starkinfra');

(async() => {
    let notes = await starkinfra.creditNote.create([
        {
            templateId: '5745297539989504',
            name: 'Jamie
