Getting started

Credentials

Before you can use the SDK, you need to be registered as a Selling Partner API developer. If you haven't done that yet, please follow the instructions in the SP-API Registration Overview. You also need to register your application to get valid credentials to call SP-API. If you haven't done that yet, please follow the instructions in Registering your Application. If you are already registered successfully, you can find instructions on how to view your credentials in Viewing your Application Information and Credentials.

Minimum requirements

To run the SDK you need Node version 14 or higher.

Install the SDK

1. Find the latest version number here.
2. Add the dependency to your project (see instructions for npm, yarn and Add as an package dependency below).

Using npm:

npm install @amazon-sp-api-release/amazon-sp-api-sdk-js

Using yarn:

yarn add @amazon-sp-api-release/amazon-sp-api-sdk-js

Add as a package dependency

Add the following line to the dependencies in your package.json file:

"@amazon-sp-api-release/amazon-sp-api-sdk-js": "^1.0.0"

Use the SDK

In order to call one of the APIs included in the Selling Partner API, you need to:

1. Configure credentials (Note: Use your individual credentials for clientId, clientSecret and refreshToken)
2. Enable auto accessToken retrievel using our built in ApiClient function OR retrieve accessToken using our LwaAuthClient helper (Be aware for some APIs, you will need extra step to get RDT Token)
3. Create an instance for a specific API and API client, then apply accessToken to it.
4. Call an API operation

For an example, refer to the following sample code for connecting to Sellers API:

import {
  SellersSpApi
} from '@amazon-sp-api-release/amazon-sp-api-sdk-js';

async function getMarketplaceParticipations() {
  try {
      //Configure Sellers ApiClient
      const sellersApiClient = new SellersSpApi.ApiClient(AppConfig.spApiNAEndpoint);
      sellersApiClient.enableAutoRetrievalAccessToken('<YOUR_CLIENT_ID>','<YOUR_CLIENT_SECRET>', '<YOUR_REFRESH_TOKEN>', null);
      const sellersApi = new SellersSpApi.SellersApi(sellersApiClient);
      
      //Call GetMarkerplaceParticipations API
      const participations = await sellersApi.getMarketplaceParticipations();
      console.log(
        JSON.stringify(participations, null, ' ') + 
          '\n**********************************'
      )
  } catch (error) {
      console.error('Exception when calling getMarketplaceParticipations API', error.message);
  }
}

getMarketplaceParticipations();

Alternatively, you can go to @amazon-sp-api-release/amazon-sp-api-sdk-js/sample-node-app and copy over and modify index.js and app.config.mjs files and give them a try. You can see multiple API operation call samples with various way of retrieving token, as well how to set up rate limiter and retry logic when making API calls. Note that the rate limiter is turned on by default to protect your API calls from 429 errors.

Additional Note:

This Amazon Selling Partner API JavaScript SDK is fully compatible with ECMAScript modules (ESM). You can use modern ES6+ import/export syntax as demonstrated in the example code:

import {
  SellersSpApi,
} from '@amazon-sp-api-release/amazon-sp-api-sdk-js';
