For sub-merchant integrations, the sub-merchant is boarded as a unique DeviceId on Portico, under a MID set up for a Payment Facilitator or Partner. 

Sub-merchant integrations are supported on the following Authorization Platforms:

• Exchange
• GSAP-NA

During transaction processing, the sub-merchant POS sends the request. Portico requests authorization from the Payment Facilitator.

• If declined, Portico returns RspCode with the value “PF”, and RspText is preceded with “Transaction rejected by Payment Facilitator” followed by any text provided by the Payment Facilitator.
• If approved, Portico processes the transaction to the front end host. When the response is received, Portico shares the result with the Payment Facilitator and the sub-merchant POS.

The sub-merchant is expected to obtain reporting from the Payment Facilitator.
