Hello,

EBay uses a two part authentication system. First, we need to get the user's consent (and specify scopes of the application), then we place the authorization code grant request to get a User access token and a refresh token. (I am following the docs here: https://developer.ebay.com/api-docs/static/oauth-consent-request.html, https://developer.ebay.com/api-docs/static/oauth-auth-code-grant-request.html.

Is it possible to support this? We would need to have a way to pass scopes. Would that be part of settings aswell?

Sorry for the questions!

Thanks!

What you describe is regular OAuth2 functionality -- the other providers do similar things. I suggest you have a look at the OAuth2Provider class, specifically the get_scope() method. As you can see there, there is already a uniform way in which providers get ahold of the scopes, so this is not something you need a custom implementation for.

I implemented some of the changes discussed. I wrote some tests (probably more than necessary), but I am not too sure how to test it
