Action Required: Prepare for General Audience Launch of New Personalization Features

[openapi-support[bot]]

Hello Developers,

The upcoming general audience (GA) launch of the new personalization features in the Etsy Open API has been scheduled for May 11, 2026. At this time, all sellers on Etsy will have access to use the new personalization tools on Etsy.

These changes will replace the single free-text personalization field with support for multiple, typed inputs (text, dropdowns, and file uploads). This has been a highly requested feature by our sellers and will give them more structured, reliable personalization data and reduce buyer errors and follow-up. To ensure a smooth transition for your users, you will need to turn on the new experience for personalization immediately after the GA launch.

Action Required

• Migrate all personalization reads and writes to the new personalization endpoints if you haven’t already
• Update your integrations to consume the new response format Release these changes to all users immediately after May 11, 2026
• Include the query parameter ?supports_multiple_personalization_questions=true on POST requests to indicate your integration is fully migrated.

⚠️ Important: Seller behavior should remain unchanged prior to the GA launch. New features like multiple and new question types will not be available to all sellers or buyers until the GA launch on May 11, 2026. Please do not share details with your users prior to this date.

Key Dates

• April 9, 2026: Your Endpoint Migration should be completed. Legacy personalization interactions will be disabled.
• May 11, 2026: General Audience Launch. Multi-question and new question type support required.**
