**gateway**

The payment failed because the payment processor does not support a feature required for this transaction. This can include unsupported transaction types, payment methods, data requirements like AVS or 3DS, or regional and currency limitations.

## Recommended Customer Message

We cannot process your transaction at this moment. Please use a different card or payment method.

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

-   **Unsupported transaction types:** Attempting to process transactions like recurring payments, refunds, or pre-authorizations that the processor does not support.
-   **Incompatible payment methods:** Using payment methods or card types that are not accepted by the processor.
-   **Missing processor capabilities:** The payment processor does not support a required feature (e.g., AVS, 3DS, Level II/III data).
-   **Regional or currency limitations:** The processor cannot process payments for specific regions or currencies.
-   **Outdated integration or configuration:** The gateway integration does not align with updated processor capabilities.

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

-   Inform the customer that their payment could not be processed because the current processor does not support a required feature.
-   Ask the customer to try a different card or payment method.
-   Ask the customer to use a method known to be supported (e.g., Visa, MasterCard, etc.).
-   Review gateway and processor configurations to ensure the supported features align with accepted card types and payment flows.
-   Consider routing certain payment methods through alternative processors that support the needed feature.
-   If the problem persists, contact Chargebee Support for further investigation and resolution.
