Allow Developers to build their own tools from an API with your site so streamers can have more customization over how Throne interacts on there stream. It would allow for programs like TITS, VTS, and many more to be able to react to a throne contribution or purchase.
Maybe a webhook at least, where a POST request is sent to a specified url, you could have a token used to identify the user so the endpoint could check if it's legitimate or not. Something similar to Ko-Fi shouldn't be too hard to implement (https://help.ko-fi.com/hc/en-us/articles/360004162298-Does-Ko-fi-have-an-API-or-webhook).
