Firebase authentication via Rest

Question

When coding a c# windows app using the Rest API for firebase is it at all possible to use Firebases facebook authentication ? or are we limited to using only the Custom auth

Answer 1

When calling the REST API, you are responsible for passing a valid JSON Web Token in the auth parameter. It has no built-in authentication methods.

You can either get a token from one the supported Identity Providers or you can mint one yourself.
