Configure the Vantiv (Worldpay) gateway to enable Level 2 and Level 3 card data processing in Zuora.

1. Select Enable L2 or Enable L3 . By selecting these checkboxes, you agree to send extra information related to a transaction to qualify for certain purchasing interchange rates. The gateway requires extra information, which must be submitted to achieve Level 2 or Level 3 Interchange rates for Visa and MasterCard. To enable Level 3 data processing, both checkboxes must be selected. For more information about Zuora's support for Level 2 and Level 3 data, see Level 2 and Level 3 Card Data.
2. In the L3 ItemData Limit field, enter the maximum number of invoice items that can be included in the Level 3 fields. The default value is 98.
3. In the Custom Field Commodity Code API Name field, enter the API name (without the __c suffix) of the Commodity Code custom field on the Product Rate Plan Charge object. This field is required to qualify your merchant account for Visa Level 3 Interchange rates. If Enable L3 is selected, this field is required.
