Mastercard

Updated on June 12, 2022

This release includes the processing rules and end-to-end interface for Mastercard s new MasterCom interface. Validation rules ensure chargebacks meet Mastercard s disputes rules. Smart dispute for Issuers supports MCOM API’s (SDK version 6) for new MCOM processing. Maestro chargebacks are still processed on legacy Chargeback processing as Maestro association has not switched onto MCOM interface yet. This release also includes the latest MasterCom related change i.e., the MCOM Collaboration Layer.
