Hi, I can help you quickly resolve the Google Merchant Center authentication issue and get your Shopify store ready for advertising. I have 8+ years of hands-on Shopify experience and have connected many stores with Google Merchant Center and Google sales channels, including digital product stores. I’ll start by identifying the exact cause of the “authentication failed” error. This usually relates to account linking, OAuth permissions, email ownership conflicts, domain verification, or Merchant Center account settings. Since your theme is clean and there are no third-party apps, this should be a straightforward fix. Once the connection is restored, I’ll verify that the Google sales channel remains stable and that your product feed is reviewed and accepted without warnings. I’ll also check required settings for digital products, tax configuration, shipping rules, and policy compliance so there are no surprises later. After everything is live, I’ll walk you through the key settings to monitor in Shopify and Merchant Center so you can avoid the same issue in the future. I’ll clearly explain what was changed and why, in simple terms. I’ll need collaborator access to your Shopify admin and Google Merchant Center. Turnaround is typically within 24 to 48 hours once access is provided. I’ve worked extensively with Shopify, Google Merchant Center, Google Ads, and feed approvals, so this will be handled end to end. Thanks, Shubham

This gives me an edge in understanding OAuth access, API permissions and potential DNS/SSL snags that can cause authentication failures. .

@Syedh1998

I’ve resolved multiple Shopify–Google Merchant Center authentication failures, and this is usually caused by one of the following: incorrect Google account permissions, Merchant Center misconfiguration, suspended GMC account, domain verification issues, or OAuth token conflicts during the sales channel connection. **My approach:** 1. Audit Shopify Google & YouTube sales channel setup. 2. Verify correct Google account is set as Admin in Merchant Center. 3. Check domain verification & claim status. 4. Review API permissions, OAuth token handshake, and account-level suspensions. 5. Reconnect the sales channel cleanly to generate a fresh authentication token. 6. Confirm product feed syncs successfully and resolve any policy warnings (especially important for digital goods). **Deliverables:** • Authentication error fully resolved • Stable Google sales channel connection • Product feed approved with no critical warnings • Clear guidance on maintaining the connection Most authentication issues are resolved within 24–48 hours once access is provided. I’ll need Shopify collaborator access and Admin access to Merchant Center. Ready to start immediately and get your products eligible for Google ads. Syed
