First Data will now provide a Partner ID that can be passed to authorization transactions. If a Partner has been given a TPP-ID from First Data and it is included in the request, it will be recorded in the database. The Partner ID is supported through the API and HCO. Payeezy Gateway now allows a shopping cart or TPP to pass to the TPP-ID with transaction data an it passes this through Compass in the current TPP-ID Field. If the Partner ID is left blank, the current default TPP ID will be sent in the transaction message.
