Hi pellenoria2, I am a developer experienced with Google Merchant Center and the Content API. I have fixed authentication problems such as OAuth token errors, service account permission issues, and API access failures. I will diagnose the auth failure, fix the connection so the Content API can create and update products reliably, and confirm that updates appear correctly in Merchant Center. Could you tell me whether your setup uses an OAuth client or a service account, and share any error messages you see? Please review my profile and portfolio to see similar fixes I have completed. I’m ready to proceed as soon as I have those details. Best regards, Saad J.

Hi there, I’ve reviewed your project to fix Google Merchant Center Content API authentication errors that block feed uploads and updates. I’m confident I can diagnose the OAuth/service account authentication flow, stabilize the connection, and verify that updates appear correctly in Merchant Center. I bring extensive experience with Google Merchant Center and the Content API, including configuring OAuth scopes, service accounts, tokens, project permissions, and handling retry/backoff for large product feeds. I’ll approach this with a structured plan: 1) replicate the auth failure in a controlled environment; 2) identify misconfigurations (OAuth client, service account, key permissions, API access); 3) implement a robust, permission-complete authentication flow; 4) validate by performing create/update operations and confirming results reflect in Merchant Center; 5) provide lightweight monitoring and error logging to catch future issues. The work will be conducted in PHP/JavaScript, with support for Google Cloud IAM and MySQL where needed. Proposed timeline and delivery: start within 24 hours of confirmation; complete a verified fix within 3-4 business days, depending on project access and scope. Next steps: I can begin as soon as you share access details or a test project, and we can align on a minimal reproducible scenario to confirm fixes. Best regards,
