Specifies two mkeys

If the merchant specifies two mkeys in the Service API request we can resolve the issue by:

  • mkey=XXX – for main processing
  • mkey_ach=YYY – for ACH processing

Syntax:
Merchant provides two mkeys in the Service API request: mkey=XXX&mkey_ach=YYY.

 The following logic is in place:

  1. If the first Payment Info (PayNo=1) for the DV customer has the payment type not ACH – we use the main mkey (XXX)
  2. If the first Payment Info (PayNo=1) for the DV customer has the payment type ACH – we use the ACH mkey (YYY)
