A Final Reminder About Migrating from Amazon MWS to SP-API Arrived

An important reminder about our existing integration with Amazon Marketplace Web Service (MWS) has arrived.

As previously notified, MWS becomes unusable after March 31, 2024.

To avoid interruption to operations using MWS, within 90 days all MWS users must either migrate fully to the Selling Partner API (SP-API) or replace existing app functionality with third-party apps.

As the required action, prepare for the final retirement of MWS access to the following MWS API sections, scheduled after March 31, 2024:

・Feeds API

・Finances API

・Fulfillment Inbound API

・Fulfillment Inventory API

・Fulfillment Outbound API

・Products API

・Recommendations API

・Sellers API

・Subscriptions API

・Push notification schemas

The SP-API documentation site, which introduces app development tutorials for SP-API, now supports Chinese, Japanese, and Portuguese.

Important notice:

From October 2, 2023, SP-API no longer requires the use of AWS IAM (Identity and Access Management). This means developers no longer need to register IAM resources or sign SP-API requests with AWS Signature Version 4. For details of the update, please check here.
