Zuora supports all of Verifi's Merchant Defined Fields (MDFs) from MDF1 through MDF20, allowing up to twenty MDFs to be passed per payment method authorization, payment, or refund transaction. MDF Fields are used to provide Verifi with important information about your business that Verifi will use when processing the transaction. Verifi may use this information for advanced transaction analysis, to trigger rules and filtering, as well as dynamically routing transactions. Information passed in these MDF fields should be accurate as the information is especially critical to mitigating and remediating fraud and risk.

MDFs are only supported via the Zuora API, with exception of MDF3 which can be configured when setting up your Verifi payment gateway using the field for "Product" (under Credentials). In the Zuora API, these MDFs are represented like this: Merchant Defined Field 1 is merchant_defined_field_1. If you would like to pass in different data for one of the MDFs in which Zuora passes default information (these are MDF1, MDF 2, MDF3, MDF6, MDF9, MDF18), you can do so utilizing gateway options .

The table below contains 3 columns:

• Verifi MDF Field Name: This is the name of the field in the Verifi gateway. In the API these fields are represented like this: Merchant Defined Field 1 is merchant_defined_field_1.

• Verifi Description: Listed are common data points to give you an idea as to the type of data commonly passed in these fields. You may not use all these fields or pass the exact data, as you would only pass the information and MDFs applicable to your business.

• Zuora Data Passed in MDF Field: Zuora will pass information in these fields by default with every payment and refund transactions (including create/update payment method, payment, create refund). Any of the Zuora data passed can be overriden using Zuora's gateway options , allowing you to customize the data passed in any of the 20 Verifi MDF fields.
