**gateway**

The payment failed because the transaction amount is below the minimum threshold set by the payment gateway, processor, or card issuer. Some payment methods do not support very low-value or micro-transactions.

## Recommended Customer Message

The payment amount is too small. Try again with a larger amount, or use a different payment method.

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

-   **Minimum amount enforcement:** The payment gateway or issuer sets a minimum charge amount that was not met.
-   **Micro-transaction restrictions:** Some cards or payment processors do not support very low-value transactions.
-   **Configuration limits:** Merchant account settings at the gateway may enforce a minimum transaction value.

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

-   Ask the customer to use an alternative payment method that allows small transactions, if available.
-   Review your minimum amount configurations at the gateway if customers commonly face this issue.
