Shopify Discontinues Support for Legacy POS UI Extensions in 2025

What Changed

Shopify has announced the end of support for eight older POS UI Extension versions (1.0.0 through 2.0.0 and the 2024-04 version) following the release of Shopify API 2025-04. Starting with POS version 9.31, any POS UI extensions built on these deprecated versions will no longer function. This change aligns with Shopify's standard API version policy, which provides 12 months of stable support for each version.

Why This Matters

If your Shopify app relies on any of the discontinued POS UI Extension versions, your point-of-sale functionality will break once merchants update to POS 9.31 or later. This could disrupt critical retail operations for your merchants and damage customer trust. Developers who haven't migrated to current versions risk losing functionality, technical support, and access to the latest POS features and security improvements.

What You Should Do

Audit your POS UI extensions immediately to identify which versions you're currently using
Update to the latest POS UI Extension version as soon as possible to ensure continued compatibility and support
Test your updated extensions thoroughly in a development environment before deploying to production
Notify your merchant customers about any updates they may need to implement on their end
Review Shopify's API version policy documentation to stay informed about future deprecation timelines

Timeline: The discontinuation takes effect with POS version 9.31, so plan your migration accordingly to avoid service interruptions.
