Koala::Facebook::APIError (OAuthException: This authorization code has been used.):

[greg]

Is anybody getting this error with the new Facebook release?

Here was the release that went into effect 12/5.  I'm now getting this error with every call...

New security restrictions for OAuth authorization codes We will only allow authorization codes to be exchanged for access tokens once and will require that they be exchanged for an access token within 10 minutes of their creation. This is in line with the OAuth 2.0 Spec which from the start has stated that "authorization codes MUST be short lived and single use". For more information, check out our Authentication documentation.

I'm getting the same error. Working to modify the code.

[greg]

Thanks. Any chance you found a solution?

I got distracted on another project. I however plan to switch to Omniauth. I was using Koala. I'm guessing that using Omniauth may be easier than modifying my Koala code to comply with the Dec 5th FB change. I'll let you when I succeed.

Does OmniAuth prevent this problem?  Anyone else succeed here?

Hey all,

This is a bit late, but there was an issue in the Koala Github repo for this -- if you're still having OAuth code issues, that might have some helpful reference.  Facebook made a pre-announced change in December to how OAuth codes are handled, and that's broken some application flows.
