Level 2 and Level 3 Processing

Capture more information to reduce interchange rates.

Credit card processing fits into three levels: Level 1, Level 2, and Level 3 processing.

Each level is defined by the amount of information needed to complete a transaction.

Level 1: Normal interchange, no additional fields required
Level 2: Lower interchange, additional fields required
Level 3: Lowest interchange, additional fields required

For Level 2 and Level 3 processing, only business-to-business merchants and the government can receive lower interchange fees. Additionally, a corporate, business, or purchase card is required to obtain the lower interchange rate for Level 2 and 3 processing.

This feature is only supported on Visa and Mastercard branded cards.
Because only business-to-business and government transactions qualify, the Merchant needs to be enabled for Level 2/3 processing.
Level 2 and Level 3 processing is only available in Live environments. This feature isn't available to test in Sandbox environments.
Tax-exempt transactions are not eligible for Level 2. They are eligible for Level 3.

Ineligible Merchants

Specific business are excluded from processing Level 2 and 3 transactions.

If a Merchant has one of the following Merchant Category Codes (MCC), they aren't eligible to process Level 2/3 transactions:

MCC Code	Merchant Description
3000-3299, 4511	Airlines/Passenger Transport
3351-3500, 7512	Car Rentals/Auto Rental
4411	Cruise Lines
5962, 5966, 5967	High Risk Direct Marketing
3501-4010, 7011	Hotels/Lodging
4112	Passenger Railways
5812, 5814	Restaurants
4722	Travel Agents
7513	Truck and Utility Trailer Rentals

Update a Merchant to Enable Level 2/3 Processing

Before a Merchant1 can process Level 2 or 3 transactions, update the Merchant resource and enable level_two_level_three_data_enabled. For more information, see Update a Merchant.

The APIs to update Merchant flags are only available for Finix Core customers. If you have additional questions, please reach out to your Finix point of contact or email the Finix Support team.

Creating Sales with Level 2 and Level 3 Processing

Once level_two_level_three_data_enabled is updated to true, the Merchant can process both Level 2 and Level 3 Transfers and Authorizations.

Level 2 and Level 3 Processing combines the data that gets requested during creation and captures it into one API call. An Authorization with Level 2 or Level 3 processing only needs to be captured if the data is different or changes from the original Authorization .

When processing Level 2 and Level 3 transactions, it's required to include additional fields when creating a Transfer and Authorization.

There are no changes in the post-payments experience (reversals, refunds, settlements, etc.) when processing Level 2 or Level 3 transactions.
The request arguments noted as required are the minimum amount of information needed for L2 or L3 interchange rates. There’s no additional benefit in passing every available request argument for a particular level.
Sales tax amount entered must be greater than 0.1% of the amount of the transaction.
If the transaction is tax exempt pass tax_exempt as true .
