Recommended Customer Message

We were unable to process your payment at this time. Please try again later or use a different payment method.

Root Cause

• Incorrect credentials: The authentication credentials (API keys, tokens, or passwords) entered are invalid.
• Expired authentication details: The provided credentials have expired and need to be updated.
• Configuration errors: Incorrect credentials have been configured in your payment gateway integration.
• Revoked or inactive credentials: The payment gateway has deactivated or revoked the credentials for policy or security reasons.

Troubleshooting and Solutions

• Verify and update the correct authentication credentials in the payment gateway configuration.
• If credentials have expired or been revoked, generate new ones and apply them promptly.
• Contact the payment gateway support team if credential issues persist despite providing valid details.
• Retry the transaction only after the correct and active merchant credentials have been configured.
• Implement credential monitoring to proactively alert when merchant credentials are about to expire or have been revoked.
