TIBCO BusinessConnect™ Container Edition 1.2.0

# AS2 Identifiers

TIBCO BusinessConnect Container Edition 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 Container Edition 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 Partner Management > Partners > Partner Name > Protocol> Edit Configurations > General tab.

Note: If the AS2 Identifier lists are left as blank, an error will show up reminding that the AS2 trading partner identifier is missing.

## Sending and Receiving

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 Container Edition, 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.

## Adding AS2 Identifiers

1. On the Partner Management tile, click Partners.
2. On the Partners page, click any partner you wish to configure this transport.
3. In the Edit Partner page, on the Protocol tab, click Edit Configurations for any protocol you wish to configure.
4. On the protocol configurations page, click the Add icon.
5. Select an AS2 domain from the Domain Type list and enter the AS2 Domain ID.
6. Click Add.

   The AS2 specification includes formatting rules for the AS2 Identifier field. AS2-To and AS2-From header information is available in section 4.2 at the following URL: http://www.ietf.org/rfc/rfc4130.txt.
