问题
In my Pinterest app I have set the Redirect URI to https://my.site.com/pinterest/callback. When doing the redirection after authentication back to my site I append a sessionid so the query becomes https://my.site.com/pinterest/callback?sessionid=<string>. This doesn't seem to work as I get
The provided redirect_uri https://my.site.com/pinterest/callback?sessionId=YA6udv2FrdjjV8juij3U5oIBBP6RoEQWWUFNzSHKaHGGf3jRq10uJ2A0-R-eYB8LLwiBTbESEdGzMY0fhYI8d7gOe3kOoPuPS6c-mowaaJBDv0J8D2I does not match any of the registered redirect URIs."
In other apis like the Instagram one this is possible. Can anyone help with this? Thanks a bunch!

I have been stucking with this for two days. Basically, Pinterest doesn't support custom parameters like other websites do, for Pinterest you need to provide the EXACT callback url and it has to use https not http, and if you need to pass custom parameters they should be in state parameter.
From Pinterest docs
state: A value you define. This can be used to make sure that the redirect back to your site or app wasn’t spoofed.
See Authentication section at https://developers.pinterest.com/docs/api/overview/
