Amount Validation
{% endcolumn %}

{% column %}
**Description**

The transaction amount is validated against configuration to make sure that the amount is within the maximum amount. For purchase, 0 amount is not allowed.

\
**Configuration Parameters**

`Merchant.Currency.MaxRefundTotalAmountPerSettlement` - the transaction amount added with Accumulated Unsettled Refund amount should not exceed Merchant.Currency.MaxRefundTotalAmountPerSettlement, else the transaction is declined. The Payment Application does not perform this validation if more than one currency is supported for the merchant, so 3rd party integrator should implement this verification if needed.
