**gateway**

The authorization or mandate linked to the transaction is invalid, expired, or has been revoked. This typically occurs with mandate-based payment methods when the authorization is no longer valid.

## Recommended Customer Message

The transaction was declined due to an invalid mandate. Try again or contact support for help.

## Root Cause[](#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-   **Invalid or expired mandate:** The authorization mandate linked to the payment has expired or is no longer valid.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[](#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.
-   Ask the customer to initiate a fresh authorization or set up a new mandate if required.
-   Ask the customer to contact 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.
