This form is just for existing apps on the Shopify App Store. For new apps you’ll need to contact partner support directly from your partner dashboard to request an exemption.
Topic summary
Migration concern: An app currently creates/edits .liquid theme files via the Asset API (available until April 2024) and asks how to replicate this with Theme App Extensions (TAE).
Key guidance: TAE does not allow creating new Liquid files. Apps must integrate as app blocks that merchants add to sections, a design choice to protect storefront performance.
Exemptions: If functionality can’t be preserved via TAE, an exemption can be requested. • Existing apps in the Shopify App Store: apply via the provided Google form. • New apps: request an exemption by contacting Partner Support from the Partner Dashboard.
Clarification of terms: • Asset API: modifies theme files directly. • Theme App Extension: ships app UI as blocks/sections configurable in the theme editor. • App Proxy page: a storefront route (e.g., /apps/…) that surfaces app content.
Open issue: A developer using an app proxy wants to render the store’s header/footer around their app content; fetching the header via Asset API returns code rather than a rendered layout. Screenshots were shared to illustrate current vs desired output. No solution was provided.
Status: Migration approach and exemption paths clarified; header/footer rendering on app proxy remains unresolved.
