Sending and receiving
Exchange WESTIM with your trading partners
The specification tells you what a valid WESTIM looks like. Sending and receiving one means mapping it to the system that holds the data, agreeing the format with each partner, and handling the messages that come back when something is rejected. XEDI does the mapping, validation and transport.
Specifications
WESTIM in every directory version
A trading partner names both the message and the directory, for example IICL WESTIM, because the segments differ between versions. Open the one your partner specified.

Frequently asked questions
Which directory version of WESTIM do I need?
The one your trading partner specifies. WESTIM is published in 1 directory version and the segment detail differs between them, so a mapping built for one version is not automatically valid for another.
How do I send a WESTIM message?
Map the data from the system that holds it into the segment structure the agreed directory version defines, then transport it by the route the partner uses, commonly AS2 or SFTP. XEDI handles the mapping, validation and transport, and surfaces the acknowledgements and errors that come back.
