how to insert a line break into a header using cURL

I want to use cURL to test a RESTful web service resource.

In that effort, one of the headers requires a linebreak to properly pass the data to the server.

In addition to endlessly searching for what I would think would be fairly common to no avail, I have tried using (\n):

curl -X POST --header "login_id: testUser" --header "passcode: testPasscode" --header "dataHeader: some data\nsome more data"  http://localhost:8080/api/test

which does not work. The line break is not recognized when the header is read at the server - I think cURL actually removes it.

I have also tried using (%0A): 

curl -X POST --header "login_id: testUser" --header "passcode: testPasscode" --header "dataHeader: some data%0Asome more data"  http://localhost:8080/api/test

How should I craft the post to insert a line break between some data and some more data?

I am using terminal on a Mac

Try passing a raw line break from the command line:

$ curl -X POST [...] --header "dataHeader: some data<press ENTER>
> some more data" http://localhost:8080/api/test
