Frequently asked questions
Question: Which Authorized redirect URIs does OsclassPoint Google Login plugin need in Google Cloud?
Answer: OsclassPoint Google Login plugin needs https://yoursite.com/ggl/1 and https://yoursite.com/index.php?page=custom&route=ggl-redirect&gglLogin=1 in Google Cloud Authorized redirect URIs. Both must match the live https host, including www if you use it. A www mismatch is a different URI and Google blocks the OAuth return.
Question: Why does Osclass Google Login plugin need two redirect URLs?
Answer: Google Login uses /ggl/1 when Friendly URLs are on, and index.php?page=custom&route=ggl-redirect&gglLogin=1 as the fallback controller route. Paste both URIs in the OAuth client so either path can complete login. A missing fallback fails when Friendly URLs are off. Match the live https host exactly.
Question: Where do I paste Google Client ID and Client secret in Osclass?
Answer: Copy Client ID and Client secret from Google Cloud into OsclassPoint Google Login plugin settings. The consent screen Authorized domains must include the Osclass host. Paste both values; a blank Client secret cannot finish the Google token step. Save the plugin, then test login on the live URL.
Question: Can I use an existing Google Cloud project for Osclass Google Login?
Answer: You can pick an existing Google Cloud project. Still add a Web application OAuth client, both Google Login plugin redirect URIs, and the site domain on the consent screen. A project used for other APIs is fine if those fields are set. Then paste Client ID and secret into the plugin.
Question: How do I add the Google Login button on a custom Osclass theme?
Answer: OsclassPoint themes such as Zara and Sigma often already print the Google Login plugin button. On a custom theme, add the plugin hook in login and register templates. Without that markup the OAuth client can work while users never see a button. Check the login page source after the hook.
Question: What should I check if Osclass Google Login fails after I save Cloud credentials?
Answer: Check four Google Cloud pieces separately: Authorized domains, both redirect URIs, Web application client type, and the consent screen. Then confirm Client ID and secret in the plugin. A domain or URI mismatch is common. Open the login URL and read the Google error instead of assuming the plugin never gets a code.
