I'm following this guide on connecting to my Parse server in Flask app. https://parseplatform.github.io/docs/rest/guide/
I have searched lot of forums but none of them tells where I can find the Parse REST API Key. My config vars doesn't have it. All I can find is, App ID, client key and server URL
if you are just connecting to your local server, use whatever you want.
Add it to the file where you got your other IDs.
All the best, and I recommend using ParsePy as that will make working with Parse in Python a lot easier.
Good luck
