Root Cause

• Missing mandatory mandate details: Required fields such as mandate ID, customer consent, or bank account information were not provided.
• Incorrect mandate data format: Submitted mandate details do not meet the formatting or validation criteria set by the payment provider.
• Outdated or invalid mandate reference: The mandate being used is either no longer valid or incorrectly referenced.
• Incomplete mandate authorization process: The customer did not complete the necessary steps to authorize the mandate.

Troubleshooting and Solutions

• Ask the customer to carefully review and update all required mandate information.
• Verify that the mandate reference is correct and currently active in the payment provider’s system.
• Ensure that all required fields are accurately populated and formatted as per the payment provider’s guidelines.
• If the mandate has expired or is invalid, request the customer to set up a new mandate.
• Contact the payment gateway support team for further clarification if the issue persists after verifying the mandate details.
