Mastercard (Send) Funding transactions

Prev Next

Overview

Mastercard Funding Transactions are transactions used to transfer funds to another account, wallet, person, or financial destination instead of purchasing goods or services.

Typical use cases include:

  • wallet funding

  • money transfers

  • account funding

  • gaming wallet top-ups

  • cryptocurrency account funding

  • securities / investment account funding

Paynetics supports Mastercard Funding Transactions through the existing Acquiring API integration for approved merchants and MCCs under the Mastercard Funding program. No new endpoint integration is required. Partners should continue using the standard Paynetics Acquiring API endpoint and request structure already implemented for card transactions. For Mastercard Funding Transactions, several existing API fields become mandatory as part of the transaction request. The standard Paynetics response structure and response codes remain unchanged.

MCCs in scope

The objective of this integration is to:

  1. Replace standard purchase transactions with Mastercard Funding transactions for specific MCCs as per Mastercard's requirements.

  2. Comply with Mastercard mandates, including submission of mandatory fields.

Mastercard Funding Transactions are supported only for approved Merchant categories and use cases. The following MCCs are currently in scope for Mastercard Funding processing:

NOTE: The applicable MCC and use case are subject to Paynetics review and Mastercard approval requirements. Mastercard Funding scope is not determined solely by MCC,  the determination is made by:

  • merchant business model,

  • use case,

  • transaction flows,

  • Mastercard rules,

  • Paynetics Underwriting/CardOps assessment.

Therefore a merchant can fall under the mandate even if its MCC is not explicitly listed in the partner guide. Wallet merchants, merchants using the payment page, or merchant using the API can potentially fall under the mandate.

Recipient currency

The supported Settlement currencies are EUR , USD, GBP, RON. There are no specific restrictions for processing currencies.

Technical integration

Once you have integrated the solution, you will run a set of tests validated by Paynetics and you will be ready to move to production.

Executing MC funding

  1. To execute Mastercard Funding use the POST /v1/purchase endpoint of the Acquiring API. Access to the Acquiring API swagger is private. It will be provided to you upon request.

Mastercard Funding Transactions Initiation:

  1. Partners can submit transaction requests with the necessary MC funding-specific fields.

  2. The API will validate all required fields to ensure accurate classification and processing. Paynetics will reject MC funding transactions with missing fields according to the requirements below.

Mandatory Fields for Mastercard Funding Transactions

The following fields already exist in the Paynetics API and must be submitted for Mastercard Funding Transactions along with the standard purchase fields.

Paynetics API field
