And if so, how do I begin to go about integrating it?
You should be able to use any REST-API with AppGyver. You can read more about REST here: https://restfulapi.net
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 https://docs.appgyver.com/data/rest-api-direct-integration
Hope this helps!
