Authorization code

authamount

If the amount authorized is different than the requested amount this is the amount that must show on the receipt. It is possible that the integration could pool multiple transactions on one receipt and in that case the authamount needs to be present for each card along with other card specific receipt data. Note that some processors do not allow pooling card data onto one receipt and require separate receipts per card.

Customers name as encoded on the card.

cardlevel

Internal interpretation of the visa 62.23 card level result returned by most processing institutions
