When you use Connect with Google (OAuth) in EmaReach, Google redirects the user back to your app after sign-in. The redirect URI is the URL Google sends them to. If that URL does not exactly match one of the Authorized redirect URIs in your Google Cloud OAuth client, Google shows an error (e.g. "Redirect URI mismatch" or "Error 400: redirect_uri_mismatch").
Get the exact URI from EmaReach
Update Google Cloud Console
Try again
Copy the Authorized redirect URI from EmaReach (Settings → Integrations → Gmail, when adding credentials), paste it into your Google Cloud OAuth client’s Authorized redirect URIs, save, then try Connect with Google again.
