App Install - Unsupported feature - Market

Shopify App Store
1

Hi,

Our app does manage the new market feature without any issue.

But when a Shopify admin displays the App Install Screen, a message appears

Unsupported features

This app is not compatible with Markets, which may affect how some features work and lead to incorrect behavior. Contact Quable PIM for more information.

The installation process goes well and everything is fine, but we can not find any clue on how to tell Shopify this is ok.

Thanks for any advice.

Hi @Tchinkatchuk!

This warning is specific to the new Markets API migration and uses separate monitoring from the regular API health system. For your app to be marked as compatible with Markets, it needs to meet two criteria:

  1. No calls to the legacy Markets API (or API versions earlier than 2025-04) in the last 7 days

  2. Active use of the new Markets API for at least 7 days

The warning persists if either condition isn’t met, even if your app appears to work perfectly with Markets. This means you can’t just add support for the new API - you need to completely eliminate all calls to the old endpoints AND give the monitoring system 7 consecutive days to verify the change.

If you’re having trouble tracking down which calls are still hitting the old API, reach out to Support who can access to logs to let you know exactly when and where your app last called the legacy endpoints.

Thank you @Donal-Shopify for the quick & precise answer.
This is what we thought. I’ll check with the team which call could be still in use, as we ware using 2025-07 & 10 and thought no legacy calls were made.

Regards,

Sylvain
