TPA for Inbound and Outbound communication

TPA with agreement ID ISO8583TPA, contains wm.estd.iso8583.tn.tpa.rec:ISO8583TPA IS document type with the following information.

Parameter	Description
schemeID	Parses incoming ISO_ 8583 messages.
senderQualifier	The field number in the ISO_ 8583 message that contains the external ID of the sender profile.
receiverQualifier	The field number in the ISO_ 8583 message that contains the external ID of the receiver profile.

Inbound communication always uses the default TPA to retrieve the schemeID, senderQualifier, and receiverQualifier details.

Outbound communication uses either message bytes or bizDoc to send messages to the trading partner.

When using message bytes,

if the schemeID is provided in the HTTP or TCP/IP clients, the module does not use TPA.

if the schemeID is not provided in the HTTP or TCP/IP clients, the module retrieves the schemeID from the TPA's "ISO8583TPA" agreement ID and, the senderID and receiverID details from the wm.estd.iso8583.tn.service:send service.

When using bizDoc,

if the schemeID is provided in the HTTP or TCP/IP clients, the module does not use TPA.

if the schemeID is not provided in the HTTP or TCP/IP clients, the module retrieves the schemeID from the TPA's "ISO8583TPA" agreement ID and, the senderID and receiverID details from the bizDoc.

Note:
If a senderID and receiverID with agreement ID "ISO8583TPA" does not exist, the module uses the default TPA to get the schemeID.
