New App Store requirements for Sidekick app extensions

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.
• 2.2.9 Don't display promotions, advertisements, or cross-sell other services in Sidekick app extensions: Don't use Sidekick app extensions to promote your app, promote related apps, or request reviews.

What this means for developers

If you’ve built (or plan to build) Sidekick app extensions, please review:

• Your extension’s TOML configuration
• Your extension’s runtime behavior in Sidekick
• Your public App Store listing

Make sure that:

• The tools, intents, and actions you expose in Sidekick stay within your app’s core functionality.
• Your extension’s configuration and behavior match how your app is described in its App Store listing.
• Your Sidekick app extension does not include promotions, advertisements, cross-sell content, or review requests.
