Credentials
Web application Name : projectprint-123
What to ask can the 1. Authorized JavaScript origins 2. Authorized redirect URIs Put EMPTY? Because I testing localhost. OK. I proceed to empty.
What is Oauth consent screen? I only fill in Email address at this part. OK. I proceed next.
Then I try
https://www.google.com/cloudprint/getauthcode? printerid=5e0db751-9498-677d-9cf3-3a7284978279&oauth_client_id=254414591833-7lg4a5nnnh009g9ccf613notg8vceunp.apps.googleusercontent.com
