List of ErrorsThe payment was declined due to a security violation detected by the payment gateway or processor. This happens when there is unauthorized system access, use of compromised API credentials, non-compliance with security policies, or suspicious payment method activity.

Root Cause

• Unauthorized system access detected: Unusual login attempts, IP anomalies, or compromised credentials suggest a security breach.
• Compromised API keys or tokens: Insecure or leaked authentication credentials were detected during the transaction attempt.
• Security policy violation: Non-compliance with required encryption standards, tokenization, or API security guidelines triggered the violation.
• Fraudulent payment method detected: The bank or payment processor identified inconsistencies or suspicious details in the payment method.

Troubleshooting and Solutions

• Review and rotate your API keys, tokens, and payment gateway credentials if a compromise is suspected.
• Immediately suspend or lock affected accounts and payment processing until the issue is investigated.
• Notify internal security teams to analyze logs, trace unauthorized access, and assess potential data breaches.
• Collaborate with your payment gateway provider to identify and resolve any vulnerabilities and ensure compliance with security protocols.
• Advise the customer to change their account passwords and enable additional security measures, such as multi-factor authentication.
