**gateway**

The payment failed because the transaction would cause you to exceed the rolling-window processing limit for a specific payment source. Gateways impose these limits based on merchant risk profiles, card type restrictions, or configured transaction rules.

## Recommended Customer Message

Your payment exceeds the limit set by your payment method. Try a lower amount, or use a different payment method.

## Root Cause[](#root-cause)

-   **Rolling-window limit exceeded:** The transaction would cause you to exceed the rolling-window processing limit for a specific payment source.
-   **Configured transaction rules:** The gateway allows merchants to set transaction rules, including maximum transaction amounts that have been exceeded.
-   **Merchant risk limits:** Gateways may impose transaction limits based on factors such as merchant risk profiles or card type restrictions.

## Troubleshooting and Solutions[](#troubleshooting-and-solutions)

-   Review your current processing limits in the gateway dashboard.
-   If you anticipate higher transaction volumes, contact gateway support to request an increase in your processing limits.
-   Inform customers proactively if a transaction cannot be processed due to limit constraints and guide them on alternative payment methods or splitting payments.
