Overview

Use this API to programmatically create a new OneSignal app. This is useful for automating app setup, particularly when managing multiple apps or organizations, and avoids needing to manually use the OneSignal Dashboard. You can create an app under an existing organization or generate a new one. Push platform configurations for Web, Android, and iOS can be defined during app creation, though Email and SMS must be set up manually via the OneSignal Dashboard.
For an overview of how apps and organizations work in OneSignal, see Apps & Organizations.
