TIBCO BusinessConnect provides the ability to communicate with trading partners using AS2-HTTP and AS2-HTTPS. For AS2 transport, two headers are added in addition to the HTTP headers: AS2-From and
AS2-To. When TIBCO BusinessConnect sends an AS2 MIME message, the values in the message’s
AS2-From and
AS2-To fields will be set with the AS2 Identifier values entered during configuration of the trading partners. AS2 identifiers are selected in the
AS2 Identifier list in the
BusinessConnect > Participants > Participant_Name > Protocols > Protocol_Name > General tab.
When a document is sent from a host to a partner using AS2, the header AS2-From contains the value agreed for the trading host and the header
AS2-To contains the value agreed for the trading partner. When an AS2 message is received by TIBCO BusinessConnect, the
AS2-To header is matched against the AS2 Identifier value entered for the host, and the
AS2-From header is matched against the AS2 Identifier entered for the partner. If there is no match, then an error is logged to indicate that an AS2 message was received from an unknown trading partner.
