# Get published URL

`GET /api/apps/platform/{app_id}/published-url`

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Returns the public URL of a published app, so you can link to it or open it.

The app has to be live. An app that has never been published, or that you unpublished, has no public URL and comes back as `404`. Publish it with [Deploy an app](/api-reference/deploy-an-app) first. A `404` also means the app does not exist, so it does not tell you which of the two happened.

<Note>The URL is always built from the app's slug, like `https://my-crm-3c45a1f2.base44.app`. If you serve the app on your own domain, that domain is not returned here.</Note>
