Deploy an app

Changed on

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

Deploys your app to production, publishing your latest changes so they go live for its users. By default the app's current version is deployed. To deploy a specific saved version instead, pass its ID in the request body. For an app whose source code you manage, pass the commit of a build uploaded with the Base44 CLI instead.
