You customize your trading partner agreements (TPAs) using the webMethods Trading Networks Console. A TPA is a set of parameters that you can use to govern how documents are exchanged between two trading partners. You customize a TPA by specifying the Sender and Receiver, and for an initiator's TPA, by also specifying the Agreement ID. You also customize a TPA by modifying certain parameter values, such as whether you want an outbound business document to be encrypted or signed. For more information about TPAs, see Customizing Trading Partner Agreements and the webMethods Trading Networks Administrator’s Guide.
