Question

I have a user authorized to access their gmail through imap using OAuth2.0. I have the OAuth2.0 access token (and refresh token). But I am having trouble figuring out how to map that into an XOAUTH parameter. All the documentation for generating the XOAUTH parameter are written assuming OAuth1.0.

I can follow the sample code make this work with OAuth1.0. But my server is using OAuth2.0 for other things and I want to use the same code.

Was it helpful?

Solution

From my Googling, I don't think it's currently possible to construct an XOAUTH param for IMAP using the OAuth2 access token. This is something Google really needs to add ASAP.
