To clarify, I understand what an API is, more or less understand how to pull and send data, and do have access to my API key.. the problem is the specific service I am attempting to use. The API links they provide have the format https://{your_app}.gingrapp.com/api/v1/reservations, but do not say where to put the key, and do not say what {your_app} is meant to be set to. I realize this is kind of a stupid problem but I am completely out of my depth and I’d really appreciate some help.
