Restangular not setting headers on post

Question

I am trying to set the header for a single post request using restangular but the request is being sent as plain text instead of json. I have read the documentation here as wel

Answer 1

Don't pass two empty objects, try passing:

.post(pip, undefined, undefined, {'Content-Type':'application/json'})

Or even .customPOST() instead of .post().
