The final authorization indicator supports a mandate from MasterCard. The purpose of the mandate is to prevent a consumer’s funds from being unavailable when there is a risk that the order will not be fulfilled. This mandate applies to you if your acquirer is in the MasterCard Europe region, which includes Russia. For details, see Credit Card Services Using the Simple Order API or Credit Card Services Using the SCMP API.
