The Selling Partner API for Fulfillment Outbound lets you create applications that help a seller fulfill Multi-Channel Fulfillment orders using their inventory in Amazon's fulfillment network. You can get information on both potential and existing fulfillment orders.

Installing

npm install @sp-api-sdk/fulfillment-outbound-api-2026-07-04
Copy

Getting Started

import {SellingPartnerApiAuth} from '@sp-api-sdk/auth'
import {FulfillmentOutboundApiClient} from '@sp-api-sdk/fulfillment-outbound-api-2026-07-04'

// `clientId` and `clientSecret` default to the `LWA_CLIENT_ID` and
// `LWA_CLIENT_SECRET` environment variables.
const auth = new SellingPartnerApiAuth({
  refreshToken: await getRefreshTokenForSeller(sellerId),
})

const client = new FulfillmentOutboundApiClient({
  auth,
  region: 'eu',
})
Copy

Rate Limiting

In order to retry rate limited requests (HTTP 429), you can configure the API client as such:

const client = new FulfillmentOutboundApiClient({
  auth,
  region: 'eu',
  rateLimiting: {
    retry: true,
    // Optionally specify a callback that will be called on every retry.
    onRetry: (retryInfo) => {
      console.log(retryInfo)
    },
  },
})
Copy

The rate limits used for each route are specified in the API documentation.

Logging

You can enable logging for both SP-API requests and responses by configuring the logging.request and logging.response properties.

const client = new FulfillmentOutboundApiClient({
  auth,
  region: 'eu',
  logging: {
    request: {
      logger: console.debug,
    },
    response: {
      logger: console.debug,
    },
    error: true,
  },
})
Copy

Specifying true will use the default options, specifying an object will allow you to override the default options.
This uses axios-logger under the hood.
By default, if enabled, the request and response loggers will use console.info and the error logger will use console.error.
