All of a sudden I've found my Google contacts-integrated web app failing to make straightforward calls to the server.
I haven't changed a stitch of oAuth code in months but all of a sudden I can't connect or make calls on existing tokens.
The return is mostly garbage but in the header I'm getting a 401 - Unauthorized and in the body you have:
Error
401
(Client Error)!!1
That's an error.
There was an error in your request.
That's all we know.
I've since tried to run a few calls in the oAuth 2.0 Playground and experienced similar behaviour. Any one else seeing this?
I've JUST seen this thread from a month ago: Google Contacts Data Api 401 error
The docs have been restored however.
GOOGLE DEVS: Any insight on this matter is MUCH APPRECIATED ASAP.
