  "description": "Object for the array of Merchant Category Codes (MCC) that the Merchant processes transactions under, and is used for risk-scoring transactions by the issuer. All MCC codes that will be processed by a DPA should be provided here (typically, this will be a single item).\n\nAn MCC is a four-character code assigned by Mastercard to the Merchant that indicates the type of business, service, or product provided by the Merchant.\n\nNote: MCC's may be assigned differently across payment networks. To avoid errors, be sure to use your assigned Mastercard MCC. This code is required for 3-D Secure (3DS) and risk profiling. If the Merchant has more than one MCC, the code most relevant to their business should be used.\n"
