[YouTube-API] Re: Urgent - well known app with 200,000+ users suddenly can't upload via oAuth2

Hello Dan,

Based on what you describe, you're using the Installed Applications
flow with urn:ietf:wg:oauth:2.0:oob as the redirect_uri, and parsing
the token from the title of the web browser's window, correct? I'm
sorry that we don't provide more than an example in the OAuth 2 guide
(https://developers.google.com/youtube/2.0/
developers_guide_protocol_oauth2) of what the window title could look
like—I agree that providing a specific algorithm (like, "always split
on '=' and use the second value") explicitly spelled out in the guide
would be very helpful. I'll sync up with the folks at Google
responsible for our OAuth 2 infrastructure and ask them to provide a
best practice that we could pass along.

In the meantime, we really can't offer any assurances about the
length of the token—it's meant to be an opaque value, and we don't
document its length as being 30 characters. The workaround you have in
place should hold you over until we can provide authoritative guidance
as to the best practice.

Cheers,
-Jeff Posnick, YouTube API Team
