The MasterCard Digital Enablement Service (MDES) is a data interchange platform for generating and managing secure digital payment tokens. The MasterCard MDES Customer Service API allows developers to deploy B2B resources that support the implementation of problem resolution portals for consumer generated queries regarding the usage of digital cards. It features functionalities that allow issuers to resolve issues of digitization, transaction processing, and lifecycle events associated with tokenized queries from consumers.
The scope of this API is restricted to B2B deployment; its provider cautions against deploying the API in B2C applications. Moreover, the API’s design restricts its processing capabilities to single token enquiries channeled by issuer customer care representatives rather than high volume token batches.
