New App Store requirements for Sidekick app extensions
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on June 17, 2026.
This Shopify update is categorized as App store, New.
What changed
We’ve introduced two new Shopify App Store requirements for Sidekick app extensions to protect platform integrity, ensure merchant transparency, and preserve trust. Starting today, all Sidekick app extensions must comply with the following guidelines: 2.2.8 Sidekick app extensions must align with stated app functionality: Sidekick app extensions must operate within the scope of your app’s core functionality. To ensure platform integrity and merchant transparency, your extension configuration, public App Store listing, and actual runtime execution must be materially consistent. Tools, intents, and actions exposed to Sidekick must be a logical representation of what your app does for the merchant on its own surface.
