Platform apps

These apps are published by LaunchMyStore in the marketplace. They are built the same way any third-party app is: OAuth install, an app manifest, the /api/v1 Admin API, functions, webhooks, an App Proxy and the extension targets. Nothing they do relies on a private hook — which makes them worked examples of the platform as much as products.

How to read these pages

Each page has two halves: for merchants (what the app does and how to set it up) and for developers (which public contracts it exercises, with links to the reference). If you are building an app in the same category, start from the developer half — the same surfaces are available to you.

The apps keep no database of their own. Settings live in shop metafields, per-order state in order metafields, and small indexes in the platform’s per-app data store — all through the Admin API with the app’s own OAuth token.
