I also implemented developer features include:

* The ability to set page layout data via API, enabling dynamic data updates.

* Support for configuring a webhook, which will send notifications when a donation is received.

The project is still in a testing and rapid iteration stage — if you encounter any bugs, please report them and they will be fixed promptly.
