HTTP Task: Submitting File

Is there a guide on steps for Submitting a file via the HTTP Task?
When I used the extression ${file_field} only the name was sent to the HTTP Target.

I used the following work-around to bypass the problem

HTTP Task > Request Body


And from the Target Service (using basic auth header)


Any better ways?

${file}, is this the file uploaded from User task using upload field in a form?
I am also trying to achieve same thing, but I could not do using Http Task.

However, I have done the same using RestClient in a Script task.

I’m not following your question - what are you trying to do? Do you have a test/ model diagram you can share?
