Selling Partner API for Node.js

A fully typed TypeScript and Node.js SDK package for Amazon Selling Partner API

Picks up changes and releases daily when/if models have drifted
Based on Axios and uses aws4-axios interceptor to automatically sign the requests
Can optionally assume roles via STS, and refresh STS credentials on schedule

Download & Installation

npm i -s @scaleleap/selling-partner-api-sdk

Getting Started

Prerequisites

A few things to get started:

Authorizing Selling Partner API

Note that it is outside the responsibility of this package to handle the authorization process.

This package assumes you have already acquired the access and refresh tokens either by going through the OAuth flow or by using a self-authorized set of credentials.

Basic Usage

Using Existing AWS Credentials

This method is applicable if you want to assume the Selling Partner API role yourself, or you are using a static set of user credentials (not recommended).

import { SellersApiClient } from '@scaleleap/selling-partner-api-sdk'

const stsClient = new STSClient({
  // Static set of credentials that have the permission to assume the role above
  credentials: {
    accessKeyId: 'AKIAIOSFODNN7EXAMPLE',
    secretAccessKey: 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYzEXAMPLEKEY',
  },
})

const { Credentials } = await stsClient.send(
  new AssumeRoleCommand({
    // This is the role you have set in your Selling Partner API application
    RoleArn: 'arn:aws:iam::123456789012:role/your-SP-API-role-name',
    RoleSessionName: 'selling-partner-api-axios',
  }),
)

const client = new SellersApiClient({
  accessToken: 'Atza|...',

  // Or use `amazonMarketplaces.CA.sellingPartner.region.endpoint`
  // from `@scaleleap/amazon-marketplaces` package
  basePath: 'https://sellingpartnerapi-na.amazon.com',

  // Or use `amazonMarketplaces.CA.sellingPartner.region.awsRegion`
  // from `@scaleleap/amazon-marketplaces` package
  region: 'us-east-1',

  credentials: {
    accessKeyId: Credentials?.AccessKeyId || '',
    secretAccessKey: Credentials?.SecretAccessKey || '',
    sessionToken: Credentials?.SessionToken || '',
  }
})

const marketplaceParticipations = await client.getMarketplaceParticipations()

Letting `@scaleleap/selling-partner-api-sdk` to Assume the Role

This package uses aws4-axios under the hood, which has the capability to make the STS call and get the credentials for you, and refresh the temporary AWS credentials session.

import { SellersApiClient } from '@scaleleap/selling-partner-api-sdk'

const client = new SellersApiClient({
  accessToken: 'Atza|...',

  // Or use `amazonMarketplaces.CA.sellingPartner.region.endpoint`
  // from `@scaleleap/amazon-marketplaces` package
  basePath: 'https://sellingpartnerapi-na.amazon.com',

  // Or use `amazonMarketplaces.CA.sellingPartner.region.awsRegion`
  // from `@scaleleap/amazon-marketplaces` package
  region: 'us-east-1',

  // This is the role you have set in your Selling Partner API application
  roleArn: 'arn:aws:iam::123456789012:role/your-SP-API-role-name',

  // Static set of credentials that have the permission to assume the role above
  credentials: {
    accessKeyId: 'AKIAIOSFODNN7EXAMPLE',
    secretAccessKey: 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYzEXAMPLEKEY',
  },
})

const marketplaceParticipations = await client.getMarketplaceParticipations()
