This section provides the various field values used to configure the different initial and follow-on transactions available.

Initial Transactions

When you process an initial transaction, Mastercard requires a reason code. When you process subsequent transactions, all card types require a reason code.
For an initial transaction, include these fields with a standard authorization request:
ccAuthService_commerceIndicator=internet
                subsequentAuthFirst=true
                subsequentAuthReason=7 //Mastercard only
When you receive the initial transaction response, save the transaction identifier. You need the transaction identifier for subsequent transactions. If you're using token management service (TMS), the transaction identifier will be stored on your behalf.

Subsequent Transactions

When you process subsequent transactions, all card types require a reason code. For a subsequent transaction, include these fields with a standard authorization request:
ccAuthService_commerceIndicator=recurring
                    subsequentAuth=true
                    subsequentAuthOriginalAmount=100.00 //Discover only
                    subsequentAuthReason=2
                    subsequentAuthStoredCredential=true
                    subsequentAuthTransactionID=12345678910
