Dan Green wrote a nice article that explains the mechanics of posting data to webMethods.
Your approach will vary depending on whether you are using TN or just Integration Server.
If you are using Trading Networks, you should use fully qualified XML because TN needs to recognize the document, the sender/receiver and then invoke processing rules.
If you are using Integration Server, you generate a web service (plenty of data around for that along with Mark Carlson’s article on web services), or you can invoke directly to a flow. Make sure the inputs are specified correctly.
As Will Kriski pointed out, there is a plethora of material available. If you are using 6.01, go to the right-hand most menu item and there is a menu choice that displays all of the developer resources that are already loaded on your machine.
Good Luck.
