REMINDER: Processing Profiles Release

[openapi-support[bot]]

This is a follow up reminder to the previous announcement!

We're excited to announce that the full roll-out of Processing Profiles is scheduled for September 29, 2025! We will plan to start releasing the feature to sellers starting at 10am ET and expect the roll out to be complete by 2pm ET. We will post follow up announcements on Github when the feature roll out is started and when it is complete.

To determine if a particular seller has access to Processing Profiles, you can check the response data of the getListingInventory, getListingOffering, and getListingProduct endpoints for presence of a readiness_state_id. Once a seller has access to the feature, it is safe to start sending Processing Profile data for that seller. For detailed instructions and examples on how to update your applications, please refer to our migration guide.

As a reminder, please refrain from making requests to create or update Processing Profiles for live seller accounts until September 29. Processing Profile data created before this date will be overwritten. Developers can continue to update processing times in Shipping Profiles during the migration period.

We appreciate your cooperation and thank you for your continued partnership. Please let us know if you have questions or need assistance.
