Description

The payment could not be processed because the gateway authentication failed. This error occurs when authentication credentials are invalid or expired, API access has been revoked, integration settings are incorrect, or the gateway requires updated authentication protocols.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 expired credentials: Your gateway credentials are incorrect or have expired.
• Revoked API access: The payment gateway has revoked your authentication tokens, preventing transaction processing.
• Incorrect integration settings: The authentication details configured in Chargebee or your system do not match those expected by the payment gateway.
• Gateway security updates: The payment gateway requires updated authentication protocols or methods that have not been implemented.

Troubleshooting and Solutions

• Verify and update the merchant's authentication credentials (API keys, tokens, or login details) in the payment gateway configuration.
• If credentials have expired or been revoked, generate new ones and update them immediately.
• Contact the payment gateway support team to resolve any outstanding authentication issues or account restrictions.
• Retry the transaction after successfully updating and validating authentication credentials.
• Set up proactive monitoring to receive alerts when authentication credentials are near expiration to prevent future failures.
