I have added the Google Pay API integration and works fine in the Staging Environment.
But when I tried to perform the transaction on Production, it gives me the below error. I tried to search the web for this error code but unable to find anything conclusive. I am using the Cybersource as a payment gateway.
This merchant is having trouble accepting your payment right now. Try using a different payment method[OR_BIBED_11]

As per @Domi's comment, i missed to submit this integration for production access. Once i got the approval from google side, this error disappeared.
