Merchant API v1beta versions discontinued

28 February 2026In force

Who is affected

Stores and apps that migrated early to Merchant API on v1beta

What it changes

v1beta calls stop working and must target v1, otherwise product feeds and imported conversions stop.

What to do

This one is settled by the app that sends your catalogue, not by your theme. Ask its publisher whether the move to the Merchant API is done, and when it was deployed on your store.
