Well, think of it like this: When you post your data into the system, the data has to have a name/value pair.
For example, the name could be $xmldata, and the value would be your data.
As a simple test, perhaps you can send in some data.
Create a flow with input of YourName. Inside the flow service, map the value of YourName into pub.flow:debugLog message input signature value. This will write the value of YourName into the server log so you can see what is coming through. Good for small values, wouldn’t recommend for large values.
With a simple html form, send in a text string with your name in it.
The name of the input variable on the html page is “YourName” and the value will be whatever you code. Whatever the value is, it should show up in the server log.
I have a feeling that the document you are posting does not have a variable assigned to it, so the server receives the communication but doesn’t know what to do with the data.
If you raise the level of your server debug log higher, you will eventually see the data coming through the post.
