Level 2 Credit Card Data Requirements
The following table lists the specific data needed and the corresponding parameter name in the PayJunction REST API. Parameters marked as required means that there is no default value for PayJunction to submit when not explicitly provided. For example, if no tax amount is provided, PayJunction will automatically submit the tax as $0.00 but cannot do the same for the purchase order.
| Common Name | API Parameter | Required | Notes |
|---|---|---|---|
| Business Name | billingCompanyName | * | |
| Card Number | cardNumber | * | Not needed when charging a card on file (token) using transactionId or vaultId |
| Transaction Amount | amountBase | * | Not needed when recharging a previous transactionId for the same amount(s). |
| Date | N/A | Handled automatically by PayJunction | |
