Migrate from Amazon Marketplace Web Service to SP-API


We’ve given sellers who integrate directly with Amazon Marketplace Web Service (MWS) and private MWS developers, more time to migrate to Selling-Partner API (SP-API). After March 31, 2024, MWS won’t be available for use.

If you have a private app connected to MWS, you have until the following dates to migrate your MWS usage to SP-API, or replace the private app with a third-party app to avoid disruption to your business automation:

  • August 31, 2023: MWS users won’t be able to retrieve data from three MWS API sections for selling on Amazon: Merchant Fulfilment Network (MFN), Orders and Reports.
  • March 31, 2024: MWS users won’t be able to retrieve data from all remaining MWS API sections.

The Amazon Selling Partner Appstore offers a selection of vetted, high-quality third-party apps to replace existing MWS integrations to help manage and grow your business.
