For merchants in Mexico processing via FEVO, Portico supports the Thank You Points loyalty program.  Cardholders can redeem points 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. 

In the response from Portico, the AuthAmt represents the amount charged to the cardholder for this transaction.  If the total of the DischargedAmt covered the full transaction amount, the AuthAmt will be zero.  The response echoes back the redeemed DischargedAmt. 

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