# POST /paapi5/* stops working

Calls to POST /paapi5/* on Amazon Product Advertising API stopped working on May 15, 2026.

On May 15, 2026, Amazon Product Advertising API removed support for POST /paapi5/* endpoints. Calls made to these endpoints fail since that date. Applications that continue to send these requests receive an HTTP 403 Forbidden response with an AccessDeniedException.

## What to use instead

Migrate to the Creators API following Amazon's migration guide.
