Amazon Selling Partner API in Go

Selling Partner API or SP-API is the next generation suite of API-based automation functionality for Amazon's Selling Partners and is an evolution of (the legacy) Amazon Marketplace Web Service (Amazon MWS) APIs, which have been offering sellers programmatic access to critical Amazon features for more than 10 years. SP-API is available in production in all the marketplaces where Amazon MWS is available.

This package provides an easy way to communicate with SP-API.

How does this work

Amazon provides swagger models for each API, and using that you will be able to form requests to the API. Some more steps are needed to have a successful call to the API, including authentication, signing the request, etc.

This package will make it easier to make authenticated requests to SP-API. The HTTP client(s) are generated from the swagger models specs using go-swagger.

To keep the client(s) up to date, there is a schedule job that runs to fetch the Selling Partner API models from Amazon's Github account, regenerate the client(s), and commit the changes to a new branch called next.

When we think that next branch is stable enough to be used, we will merge it into the master branch and create a new version out of the new or updated models.

Installation

go get github.com/renabled/amzn-sp-api-go

Example

import (
  "fmt"

  "github.com/renabled/amzn-sp-api-go/api/sellers/sellers_client/sellers"
  "github.com/renabled/amzn-sp-api-go/selling_partner"
)

// Initilize your config
config := selling_partner.NewConfig(
  "_accessKeyId_",
  "_secretKey_",
  "_roleArn_",
  "_refreshToken_",
  "_clientID_",
  "_clientSecret_",
  "region", // NA, EU or FE
)

// Create a selling partner client providing the config
cli := selling_partner.New(config)

// Transport that require auth
transport := cli.ClientTransport(
  context.Background(),
  /* selling_partner.Grantless(), selling_partner.Debug() */)

// Call sellers
sellersCli := sellers.New(transport, nil)

// Make the actual request
res, err := sellersCli.GetMarketplaceParticipations(sellers.NewGetMarketplaceParticipationsParams())

fmt.Println(res, err)
