The Cloud App Licenser API is designed to be communicated with using HTTP POST requests (using either native code on native apps, or web-based languages on hybrid apps) and returns JSON data in response. You can use the API to issue Licenses to end-users and associate In-App Credits to specific License Keys. By locally storing values returned by our API, you can maintain an end-user's in-app activity between sessions, and optionally across devices (where data associated with a license is stored remotely).
