[google-api] Error: invalid_client no application name
As @Chris-Kempen says, you have to recreate all necessary OAuth ids AFTER you have set the support email for your application.
If you create OAuth credentials BEFORE you set the support email address in the consent screen, then it appears that you will always get this error.
I am using Google Apps API for my application and trying to authorize it using OAuth2. I have created a project and an application within it using the Google API console. I am using the following URL for authorization:
https://accounts.google.com/o/oauth2/auth&scope=https://www.googleapis.com/auth/admin.directory.user&redirect_uri=urn:ietf:wg:oauth:2.0:oob&response_type=code&client_id=(my application clientid)
I get the following error,
Error: invalid_client no application name Request Details
I have verified the clientid and even the status of admin SDK.
