Surcharging
A surcharge is an additional amount charged by the merchant to cover the cost of accepting card payments. The Mastercard Gateway's surcharging functionality allows you to apply a surcharge on a transaction based on the following parameters:
- gateway entry point, for example, Hosted Checkout, API
- payment method, for example, Mastercard, Visa, American Express
- funding method, for example, Credit, Debit
- currency
To allow the gateway to compute a surcharge for a transaction, you must configure surcharge rules in Merchant Administration. Alternatively, you can provide a pre-calculated surcharge on the order if you are integrating using API/Batch.
Prerequisites
- You must be enabled for surcharging on your merchant profile with the Mastercard Gateway.
- You must have surcharging rules configured in Merchant Administration to allow the gateway to calculate the surcharge.

FAQs
Will the gateway calculate the surcharge if I provide both order.netAmount and order.amount fields in my request?
Providing both order.netAmount and order.amount fields without order.surchargeAmount will return an error because the gateway does not have sufficient information to calculate the surcharge. The gateway requires you to provide either the order.netAmount field OR the order.amount field.
If you provide all three fields then the gateway will not calculate the surcharge instead use the surcharge amount as provided by you.
Can I opt out of surcharging card payments when submitting a transaction?
Yes, to opt out of surcharging,
- provide the order.amount field in your transaction request to indicate the total amount for the order.
for Direct API from WSAPI version 50 to 66,
- when the surcharge is calculated by the merchant, do not provide value in the fields order.netAmount and order.surchargeAmount.
- when the surcharge is calculated by the gateway, do not provide value in the field order.netAmount.
for Direct API from WSAPI version 67 and above,
- when the surcharge is calculated by the merchant, do not provide value in the fields order.netAmount, order.merchantCharge.amount, and order.merchantCharge.type as surcharge.

- surcharge is always calculated by the gateway, do not provide value in the field order.netAmount and order.merchantCharge.type as surcharge.
If the payer requests a refund, will the surcharge amount be refunded?
Yes. Because the surcharge is included in the order.amount field, and it is this amount that's refunded to the payer, the surcharge amount will be refunded too. In case of partial refunds, the surcharge amount will be refunded on a pro rata basis.
If I have Dynamic Currency Conversion (DCC) enabled, will the gateway calculate the surcharge in both the payer's billing currency and my preferred currency?
Yes, the gateway will include the applicable surcharge in the order amount, which will be returned as paymentTypes.card.currencyConversion.payerAmount in the payer's billing currency and as order.amount field in your preferred currency (in the Payment Options Inquiry operation response).
Can I retrieve card type identification data to help calculate a surcharge for an order?
You can provide the sourceOfFunds.provided.card.prefix field in the Payment Options Inquiry request to retrieve the following scheme/funding details about the card used for payment, which may assist you in surcharging decisions:
paymentTypes.card.scheme: The organization that owns a card brand and defines operating regulations for its use.paymentTypes.card.brand: The brand name used to describe the card that is recognized and accepted globally. For many major card types this will match the scheme name. In some markets, a card may also be co-branded with a local brand that is recognized and accepted within its country/region of origin (see Local Brand).paymentTypes.card.localBrand: The brand name used to describe a card that is recognized and accepted within its country/region of origin. The card may also be co-branded with a brand name that is recognized and accepted globally.paymentTypes.card.fundingMethod: The method used by the payer to provide funds for the payment.
You can use these details to calculate a surcharge based on the card presented by the payer.
