For merchants in Mexico processing via FEVO, Portico supports the Thank You Points loyalty program.  Cardholders can redeem points or apply a discount to cover the full or partial amount of a purchase. The point redemption information is supported for CreditSale only, using the TYPoints data block.  The amount of the request covered by points is sent in the DischargedAmt field, and the discount is sent in the DiscountAmt field. 

In the response from Portico, the AuthAmt represents the amount charged to the cardholder for this transaction. If the combined total of the DischargedAmt and DiscountAmt covered the full transaction amount, the AuthAmt will be zero. The combined deductions may not exceed zero. The response echoes back the redeemed DischargedAmt and the DiscountAmt.

If a transaction utilizing Thank You Points needs to be reversed for any reason, it must be reversed in full; partial reversals are not supported. The CreditReversal request may contain either the AuthAmt or the requested amount of the original sale.
