# Level 2 and 3 Data
source: https://developer.mastercard.com/mastercard-gateway/documentation/gateway-features/trans-enrich-data/order-and-line-item-data/level-2-and-3/index.md

A credit card transaction can be submitted with three levels of transaction data: Level 1, Level 2, and Level 3. Each level is defined by the amount of information provided to process the transaction.

* Level 1 includes standard transaction data, such as, date, card number, and total order amount.
* Level 2 includes Level 1 data plus enhanced transaction data, such as customer reference number, invoice number, and sales tax amount.
* Level 3 includes Level 2 data plus line item details.

The following methods are supported:

| Integration methods | Payment methods |                            Transactions                            |
|---------------------|-----------------|--------------------------------------------------------------------|
| All                 | Credit cards    | * AUTHORIZE * PAY * VERIFY * CAPTURE * REFUND * AUTHENTICATE PAYER |

To view examples of API requests with Level 2 and 3 data, download the [Postman collection](https://www.postman.com/mastercard/mastercard-developers/collection/4fakvrd/mastercard-gateway-api).
Tip: Mastercard Gateway recommends that API requests contain fewer than 65,000 characters. Warning:   

* If you accept business, corporate, or purchase cards, providing Level 2 or 3 data on your transaction can qualify the transaction for better interchange rates.  
  Your customer's business can also benefit from itemized card statements as well as information to support and streamline business processes, such as purchasing authorization, reconciliation, and reporting.
* Your payment service provider does not validate that the data provided on the transaction is sufficient to qualify for specific interchange rates as required by the card schemes.
* The support for Level 2 and 3 data is only available from API v42 onwards.

## Providing Level 2 and 3 data {#providing-level-2-and-3-data}

In \[initial transactions\], when you create an order, all Level 2 and 3 data that you provide applies to all transactions on the order. On \[subsequent transactions\], [Capture](https://developer.mastercard.com/mastercard-gateway/documentation/api-reference/v100/rest/api-ops/index.md#transaction) or [Refund](https://developer.mastercard.com/mastercard-gateway/documentation/api-reference/v100/rest/api-ops/index.md#transaction), you only need to provide Level 2 and 3 data when you want to.

* Override the data that you provided for the order.  
  You can override the Level 2 and 3 data for the order. You can do this to correct information that was provided when you created the order. The updated information then applies to all subsequent transactions on the order. For example, `order.customerReference`.

Warning: You can only override those order fields that are allowed in a specific subsequent transaction. For example, order.amount can only be provided in an AUTHORIZE request, so you cannot override it in a subsequent CAPTURE request.

See the Order-level field or Transaction-level Field column in the Level 2 and 3 data tables.

* Provide data that only applies to the transaction.  
  You can provide Level 2 and 3 data that only applies to the specific transaction. For example, `transaction.taxAmount`.  

See the Order-level field or Transaction-level Field column in the following Level 2 and 3 data tables.

* Perform CAPTURE or REFUND transactions where the transaction amount differs from the order amount. In these cases, you must provide Level 2 and 3 data on the transaction, such as amounts or line item details, as these cannot be defaulted from the order.

## Providing Level 2 and 3 data with EMV 3-D Secure {#providing-level-2-and-3-data-with-emv-3-d-secure}

If you use the gateway to perform [EMV 3-D Secure authentication](https://developer.mastercard.com/mastercard-gateway/documentation/security-and-fraud/authentication/3d-secure-auth/index.md) for your payment transactions, you can create an order by submitting an [Initiate Authentication](https://developer.mastercard.com/mastercard-gateway/documentation/api-reference/v100/rest/api-ops/index.md#authentication) request followed by an [Authenticate Payer](https://developer.mastercard.com/mastercard-gateway/documentation/api-reference/v100/rest/api-ops/index.md#authentication) request with Level 2 and 3 data. If you provide Level 2 and 3 data in the AUTHENTICATE PAYER request, provide the `authentication.transactionId` field in the subsequent AUTHORIZE, PAY, or VERIFY payment request. Level 2 and 3 data are populated from the referenced authentication. You can submit the same or different Level 2 and 3 data on your payment request to override Level 2 and 3 data provided on authentication.
Warning:   

* If the order.amount provided in the AUTHORIZE, PAY, or VERIFY request differs from the order.amount of the authentication, Level 2 and 3 data is not copied from the authentication.  
  In this case, you must provide Level 2 and 3 data in the payment transaction.
* The AUTHENTICATE PAYER request supports:
  * Level 2 fields from API v64 onwards
  * Level 3 fields from API v77 onwards

## Sending the data to your acquirer {#sending-the-data-to-your-acquirer}

When the gateway sends Level 2 and 3 data to your acquirer, the values provided on the transaction take precedence over the values provided at the order level. If you do not provide values on the transaction, the gateway uses the values provided at the order level to send to the acquirer, as applicable.

The submitted data is returned in the transaction response.

### Level 2 data {#level-2-data}

To provide the following Level 2 data in your transaction request, use the corresponding order-level or transaction-level API fields as shown in the following table.

The order-level fields are copied into the transaction-level details unless the merchant submits a different amount or quantity in partial CAPTURE requests.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 ||
