Additional Ticket Fields for Autotask Intergration

If your are not aware you should be able to edit the soap xml values to fill in whatever fields you need.

I don't use Autotask myself but it looks very similar to other Integrations. When you setup an integration, you will fill some values on the top half and then click on a Generate button. This will then auto-populate the HTTP Delivery section based on your values. You can edit the various parts of the HTTP Delivery section and modify the default Soap XML request to add in any other field you want to add. You can use various LM Tokens or hard-coded values.
