Configure the Braintree v2.0 gateway to enable Level 2 and Level 3 card data submission for potentially lower interchange rates.

1. Select Enable Level 2 Processing and Enable Level 3 Processing . With these settings enabled, additional information such as the amount of sales tax and order and line items will be passed to the gateway when processing a credit card transaction. This information might result in lower interchange rates on eligible commercial, corporate, and purchasing cards. For more information about Zuora's support for Level 3 and Level 2 data, see Level 2 and Level 3 Card Data .
2. In the CommodityCode Custom Field API Name and ProductCode Custom Field API Name fields, enter the API names of the CommodityCode and ProductCode custom fields on the Product Rate Plan Charge object, respectively. Enter the API name without the __c suffix. These two fields are required to qualify your merchant account for Level 3 interchange rates. If these fields are not specified, the Level 3 data will not be sent to the Braintree gateway.
