Root Cause

• Invalid or expired mandate: The authorization mandate linked to the payment has expired or is no longer valid.

• Mandate revoked: The customer or their bank has revoked the previously given payment authorization.

• Incorrect payment setup: The payment was initiated without a valid or complete mandate configuration.

• Gateway validation failure: The payment gateway rejected the mandate as invalid during transaction processing.

Troubleshooting and Solutions

• Inform the customer that the transaction failed due to an invalid payment authorization.

• Ask the customer to:

  • Review and update their payment authorization details, if possible.

  • Initiate a fresh authorization or setup a new mandate if required.

  • Contact customer support for assistance in resolving the authorization issue.

• Avoid retrying the payment automatically until a valid mandate is available.

• If the customer initiates a new mandate, attempt the payment again using updated authorization credentials.
