Root Cause

• Mandate expiration: The authorization mandate expired after a fixed validity period.

• Mandate deactivation: The customer or their bank deactivated the mandate.

• Bank-side cancellations: The mandate was canceled by the issuing bank due to account changes or policy updates.

• Lack of recent activity: Some mandates are automatically set to inactive after long periods of inactivity.

Troubleshooting and Solutions

• Inform the customer that their payment could not be processed due to an inactive mandate.

• Email the customer with a 'Pay Now' link or provide instructions to set up a new mandate.

• Guide the customer through completing a new mandate authorization to enable future payments.

• Avoid retrying the transaction automatically until a new mandate is successfully registered.
