We are requesting a supported App Store Connect API endpoint for creating a new app record, for example POST /v1/apps.
We run an automated "create app" workflow that sets up new apps as part of our app management service. The App Store Connect API supports reading and updating apps, but the Apps documentation (https://developer.apple.com/documentation/appstoreconnectapi/apps) lists no way to create one. A new app can only be created on the App Store Connect website.
Today our approach is using a third-party library (fastlane's Spaceship) that calls the private endpoints behind the App Store Connect website. Those endpoints can change at any time, and if they do, app creation and our automation will stop working. A supported endpoint, authenticated with an App Store Connect API key, would let us create apps reliably. Thank you for considering this request.
