The transaction failed because the authorization code is missing or invalid. This error occurs when the transaction request does not include a valid authorization code, the system failed to supply it properly, the code has expired, or the issuer did not generate one.

Root Cause

• Missing or invalid authorization code: The transaction request did not include a valid authorization code required for processing.
• Incorrect integration or configuration: Your system failed to supply the authorization code properly during the transaction request.
• Authorization code expired or invalidated: The provided code is no longer valid due to expiry or a prior reversal.
• No code generated by issuer: The initial transaction failed to receive an authorization code from the issuer, leading to incomplete processing.

Troubleshooting and Solutions

• Verify that the merchant payment system correctly captures and submits the authorization code during the transaction process.
• Ensure transaction flows are configured to handle and store authorization codes properly for subsequent processing steps.
• If the issue persists, contact the payment gateway for further assistance.
• Retry the transaction only after confirming that the authorization code is correctly generated and included in the request.
