This section contains suggestions and solutions to problems that may occur with your integration.
The surcharging functionality on Mastercard Gateway allows a merchant to apply a surcharge on a transaction based on the following parameters:
- Gateway entry point such as Hosted Checkout or API.
- Payment method such as Mastercard, Visa, or American Express.
- Funding method such as Credit or Debit.
- Currency
Yes, you can configure the IP Country filtering rules in Merchant Administration. Your payment service provider can configure rules for you in Merchant Manager, in addition to rules that apply to all their merchants. This will allow you to reject or review transactions that originate from the IP addresses associated with high-risk countries.
Refunds can be performed only when a funds transfer is completed either through a Pay or a Capture.
Void (Cancel) can be performed only on transactions that have not been sent to the bank by the acquirer for processing at the end of the day.
Yes, you can set a recurring payment with a variable amount, for example, payment of post-paid bills. You need to update the amountVariability parameter value according to the requirements. For more information, see Credential On File Transactions.
The main difference between the two SDK versions are as follows:
| SDK version 1 | SDK version 2 |
|---|---|
| No native in-app experience | Native in-app experience, without redirects |
| Challenge flow with redirects | Multiple challenge flows such as OTP, single and multi-select, answer-based are supported. |
| Issuer challenge flow through web browser on a mobile device | Smarter frictionless flow that leads to lesser challenges for payer |
This depends on the financial institution who issued the card to the payer. Each card issuer defines the authorization expiry period in which they hold the funds on the payer's account, while they wait for the arrival of the capture transaction. Generally, it is 5-8 processing days, before the authorization purges from the payer account and access to the funds are released back to the payer.
You can use the following fields to catch validation errors:
The field error.explanation [REST][NVP] will contain some human readable error text giving further information about the error, such as minimum or expected length, etc. Do not parse this information as the format for this text cannot be guaranteed.

Yes, it's safe to resubmit a request with the exact same details because the gateway supports idempotent operations. Idempotent operations produce the same result when invoked repeatedly. If the gateway has already received your request, it will return the original response; otherwise, it will process the request and return the response.
Typically, you can match up requests to responses using order.id and transaction.id fields as these are provided in the requests and returned in the responses. However, if your application does not support a synchronous integration model or your source and target for a request differ, you can use the field correlationId to identify the request and its matching response. correlationId is a transient identifier, the value for which does not persist in the gateway and is returned as provided in the response to the request. You can use the correlationId with all Web-Services API requests.
No merchant acquirer link error for an acquirer I am configured for?Please contact your payment service provider to make sure your merchant acquirer link on the gateway is configured for the required card type and currency combinations.
Merchant Administration is a web-based interface that allows merchants to easily view and manage their orders. The merchants can search and view their order/transaction details, download CSV reports, check 3-D Secure results, set up risk controls, create orders manually, manage refunds, and much more. Refer to Merchant Administration User Guide for more details.
Merchants need to be boarded on the gateway and have their merchant profile configured successfully to access Merchant Administration.
The issuer or card network may provide additional information in the form of a Merchant Advice Code, which will help you understand the reason for declining the transaction. When a transaction is declined for insufficient funds, the advice code may recommend a retry time frame to merchants in which an authorization approval is likely to be successful. For more information about Merchant Advice Codes for declined transactions, refer to Transaction Errors.
