How to fix Google Pay issues on a one-page website

Question

Accepted Answer

To fix Google Pay issues on a one-page website, first, thoroughly review your Google Pay API integration code to ensure all parameters are correctly configured. Verify that your Merchant ID and allowed payment methods (like card networks) are accurate and match your Google Pay Business Profile settings. Utilize your browser's developer console to check for any JavaScript errors or network failures during the payment process, which often pinpoint front-end misconfigurations. Ensure your site uses HTTPS, as Google Pay explicitly requires a secure context, and test the functionality across multiple browsers and devices to rule out client-specific problems. Check your server-side logs for any backend processing errors related to token decryption or transaction finalization. Finally, consult the official Google Pay documentation for any recent API changes and ensure your users have clear, visible payment instructions.
