Invalid_client error with gmail contacts oauth

[yangtheman]

Hi! First of all, thanks for the gem!

I think this requires a simple fix, but not sure where to look/see since it looks like I have everything correctly....

I have a link to [my_domain]/contacts/gmail on a test page. When I click on the link, I get the following error. I double-checked OAuth Key and Secret, and they are correct.

Error: invalid_client
Request Details
scope=https://www.google.com/m8/feeds
response_type=code
access_type=online
redirect_uri=http://[my_domain]/contacts/gmail/callback
approval_prompt=auto
client_id=[OAuth Consumer Key]

Any help would be much appreciated!

Thanks.

That's very strange indeed. Please, check out this example to see if you have done everything right: https://github.com/sonianand11/omnicontacts_example

Ha. I figured it out. It turned out that I got the wrong OAuth credentials. I was following this article and went here to get OAuth credentials, but this was the WRONG place.

The correct place is Google API Console and create a new project to get the right OAuth credentials. Diego, you might want to mention it in the README.
