Obtaining Essential Credentials

In order to obtain the refreshToken, clientId, and clientSecret, you'll need to follow the instructions below:

1. Follow these instructions to retrieve clientId and clientSecret.
2. Run ask util generate-lwa-tokens to generate a refreshToken (copy the value from refresh_token and use it to initialize refreshToken in the next step).
3. Create a file called secrets.json which should look something like:

{
  "refreshToken": "generated by ask util generate-lwa-tokens",
  "clientId": "amzn1.application-oa2-client.myClientId",
  "clientSecret": "myClientSecret"
}

And here is some example code to test that the credentials are valid:

const mySmapiClient = require('node-alexa-smapi')();
const mySecrets = require('./secrets.json');

mySmapiClient.tokens.refresh({
  refreshToken: mySecrets.refreshToken,
  clientId: mySecrets.clientId,
  clientSecret: mySecrets.clientSecret,
}).then(() => {
  mySmapiClient.vendors.list().then(result => {
    console.log(`My vendor list: ${JSON.stringify(result, null, ' ')}`);
  })
});

See the examples part for more examples.

Documentation

Official Documentation: https://developer.amazon.com/docs/smapi/ask-cli-intro.html#smapi-intro

All methods return a promise, which either resolves to the SMAPI data received, or rejects with an error.

Constructor

// Constructor for building the SMAPI REST client.
// params should be in the form: {version: "v0, or v1 (default)", region: "NA (default), EU, or FE"}.
Object alexaSmapi(optional Object params)

Constants

// All possible base URLs. By default, the NA url is used.
const BASE_URLS = {

const alexaSmapi = require('node-alexa-smapi');
var smapiClient = alexaSmapi(optional Object params);
smapiClient.tokens.refresh({
  refreshToken: "MY_REFRESH_TOKEN",
  clientId: "MY_CLIENT_ID",

Miscellaneous Functions

alexaSmapi.refreshToken(String accessToken)

// Sets the new base URL for future API calls.
alexaSmapi.setBaseUrl(String url)

Custom API calls

Due to its recent release to the public, some API methods may not be covered by this module. In that case, a bunch of custom functions are available to use. They will return the response received from making the call.

// Perform a custom HEAD request
alexaSmapi.custom.head(String url)

// Perform a custom GET request
alexaSmapi.custom.get(String url, Object parameters)

// Perform a custom POST request
alexaSmapi.custom.post(String url, Object parameters)

// Perform a custom PUT request
alexaSmapi.custom.put(String url, Object parameters)

// Perform a custom DELETE request
alexaSmapi.custom.delete(String url)

Examples

Note that you'll always need to have a valid refreshToken, in which you can obtain that code below:

const mySmapiClient = require('node-alexa-smapi')();
const mySecrets = require('./secrets.json');

mySmapiClient.tokens.refresh({
  refreshToken: mySecrets.refreshToken,
  clientId: mySecrets.clientId,
  clientSecret: mySecrets.clientSecret,
}).then(() => {
  // do something with the SMAPI client...
});

Using Promises

const mySmapiClient = require('node-alexa-smapi')();
const mySecrets = require('./secrets.json');

mySmapiClient.tokens.refresh({
  refreshToken: mySecrets.refreshToken,
  clientId: mySecrets.clientId,
  clientSecret: mySecrets.clientSecret,
})
.then(() => smapiClient.skills.getManifest(skillId, 'development'))
.then(data => console.log(data))
.catch(error => console.log(error));

Using Async/Await

const mySmapiClient = require('node-alexa-smapi')();
const mySecrets = require('./secrets.json');

(async function() {
  try {
    await mySmapiClient.tokens.refresh({
      refreshToken: mySecrets.refreshToken,
      clientId: mySecrets.clientId,
      clientSecret: mySecrets.clientSecret,
    });
    
    let manifest = await smapiClient.skills.getManifest(skillId, 'development');
    console.log(manifest);
  } catch (error) {
    console.log(error);
  }
})();
