It seems like you’re asking about the “OR-CCREU-01” error, which is another payment-related issue tied to Google services, such as Google Pay or Google Play. This error typically appears as “Transaction declined: invalid payment method. [OR-CCREU-01]” and indicates that the payment method you’re trying to use has been rejected, either by Google’s system or your bank.

The root causes are often similar to other payment errors like OR-CCSEH-26:

• Card Issues: The card might not support online or international transactions, could be expired, or has incorrect details entered (e.g., CVV, billing address).
• Bank Restrictions: Your bank might be declining the transaction due to security settings, insufficient funds, or a requirement for two-factor authentication (2FA) that Google’s payment flow doesn’t fully handle.
• Google Account Glitch: Sometimes the payment method isn’t syncing properly with your Google account, or it’s flagged for verification.

Here’s how to tackle it:

1. Verify Card Details: Go to pay.google.com, check your payment methods, and ensure all info (card number, expiry, billing address) is correct and up-to-date.
2. Test with Another Card: If possible, add a different debit/credit card or payment method (like a virtual card or UPI, if supported) to see if it’s specific to one card.
3. Contact Your Bank: Ask if they’re blocking the transaction and why—sometimes enabling online payments or adjusting security settings fixes it.
4. Re-add the Payment Method: Delete the card from your Google account and add it back fresh. This can clear any syncing issues.
5. Check Internet Connection: A weak or unstable connection can interrupt the payment process—switch to a reliable network.
6. Wait and Retry: If it’s a temporary glitch (on Google’s or your bank’s side), waiting a day or two before retrying can work.

If you’re still stuck, it might be worth reaching out to Google Support via support.google.com, though their response might not be instant.
