A secure Authentication and Acknowledgement (AUTACK) message enables in the transmission of the referenced EANCOM message for integrity and authenticity. The AUTACK message is used to transport the digital signature along with the EANCOM message and the related information that is needed by the recipient to verify this digital signature.

The security services provided by the cryptographic mechanisms are applied to the structures of the referenced EANCOM message (Interchange, Group, or Transaction). The result of this forms a part of the AUTACK message body in addition to the reference number, and date and time for the EANCOM message.

An AUTACK message is sent by the sender of the EANCOM message to the receiver for providing authenticity, integrity, and non-repudiation of the original EANCOM message by way of security services provided by the electronic signatures. The applied security procedures are agreed between the trading partners and is set in the EDITPA Trading Partner Agreements page in My webMethods.

Module for EDI provides the wm.b2b.edi.eancom:generateAUTACK built-in service to generate an AUTACK message manually. Use the wm.b2b.edi.eancom:processAUTACK service to process an AUTACK message manually. To generate an AUTACK message, invoke the generateAUTACK service from the service that you create to build an EDI document. To process an AUTACK message manually, invoke the processAUTACK service from the service that you create to process an EDI document.

For more information about the wm.b2b.edi.eancom:generateAUTACK and wm.b2b.edi.eancom:processAUTACK services, see webMethods Module for EDI Built-In Services Reference.

To generate the outbound AUTACK messages automatically, use the EANCOMAUTACK/autoGenerateAUTACK EDITPA variable in the My webMethods Trading Partner Agreements page. Similarly, to process all the inbound AUTACK messages automatically, use the EANCOMAUTACK/processInboundAUTACK EDITPA variable. For more information, see webMethods Module for EDI Installation and User’s Guide.
