Business Rules

The following table lists business rules relevant to the PPS Gateway for AIR Card®, along with their corresponding APIs:

API	Rule
Void	To void a transaction, the batch that includes the transaction must be open.
Sale	Some AIR Cards® only allow for the billing of fuel and not for other types of services.
Sale	If you specify a time in the `deliveryDate` property of a `details` subobject of a Sale, you must use UTC time.
Sale	If you input an `eProcessingType` of `CONTRACT`, the gateway will check if you are under contract for those products with the airport at the time of the transaction.
Sale	If you are not under contract at an airport, you cannot send transactions to the gateway if another merchant is under contract at the same airport for those contracted products (though system overrides may apply).
Sale	A `details` subobject of a Sale can only include one item of type `Fuel` but can have several non-fuel items.
Sale	If an item is a fuel type, the properties `deliveryDate` and `deliveryTicketNumber` are required in the `details` subobject of a Sale.
Sale	The gateway will mark a transaction as a possible duplicate if you submit one with the same location and same amount of fuel and the same card and tail number as another within 48 hours (though system overrides may apply).
Sale	You cannot include the taxes and fees that have been specified in a `taxAndFeesBreakdown` subobject of a Sale in the `invoiceTotal` property of the invoice subobject.
Sale	If you charge a "vendor fee" for non-fuel items, the gateway validates that the percentage of this fee in relation to the total value of non-fuel items matches the percentage that you specified in your configuration.
Sale	If you charge a "vendor fee" for non-fuel items, you must include this fee in a `details` subobject of a Sale and not in a `taxAndFeesBreakdown` subobject.
Sale	You can only include taxes and fees that the gateway has approved in a `taxAndFeesBreakdown` subobject of a Sale.
Sale	If you've applied a government discount to a transaction, you must reflect this discount in the difference between the `postedPrice` and the `unitPrice` properties of the `details` subobject of a Sale.
Sale	The gateway validates the fuel capacity of an aircraft, and it does not allow the purchase of fuel above what has been established (though system overrides may apply).
Sale	If you are a third-party merchant with an `eProcessingType` of `RETAIL`, you must send the gateway the price of fuel prior to transaction initiation, and the gateway will then validate this price in ongoing transactions.
Sale	If an item in a `details` subobject of a Sale has a product type of `Fuel Related`, there must be another item in the subobject that has a product type of `Fuel`.
