Hi,

I just did a simple OAuth demo and I don't consider myself as an expert in that field but I guess there could be several problems.

If I remember correctly, you have to create your Google credentials for "native" applications and you have to select the right "scope" in your application for the service you want to access.

You have to add the token in the "Authorization" HTTP header and it's only valid for some time.

Read the code comments and the liked documents for more information :

Try the OAuth2Tester demo to see if it works with your credentials.
