Description

The payment could not be processed because authentication is required by the payment gateway. This error occurs when authentication credentials are invalid, missing, or expired, the integration setup is incomplete, or the gateway is enforcing updated security protocols.

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

• Invalid or missing credentials: Your authentication credentials (API keys, tokens, or passwords) are incorrect or have expired.
• Revoked or expired API keys: The credentials used to access the payment gateway are no longer valid.
• Incomplete integration setup: Authentication details were not properly configured in the payment system.
• Security policy enforcement: The payment gateway is enforcing updated authentication protocols that have not been implemented.

Troubleshooting and Solutions

• Verify and update the authentication credentials used to connect with the payment gateway.
• Regenerate API keys or tokens if they have expired or been revoked, and update them in the system.
• Retry the transaction after ensuring the correct and active authentication details are in place.
• Contact the payment gateway support team if authentication issues persist despite updating the credentials.
• Implement monitoring to proactively check for credential expirations and prevent future authentication failures.
