How do I know if an API is compatable with Appgyver?

And if so, how do I begin to go about integrating it?

Hi there!

You should be able to use any REST-API with AppGyver. You can read more about REST here:

To get started I recommend you first read the documentation for the API you want to integrate with and then read through the docs on AppGyver’s REST API direction integration

Hope this helps!
