Referer value in the http Request Header

Hello, I have an app running on web0S SmartTV. I need to send requests to some REST service and in order to do that and to be additionally authorized, I need to send in my http request header the specific value for “referer”. That is what I use in my web app and it’s automatically generated on web, due to the URL of my web app. Is there a way that I can send some custom data in the Referer field of Request header, in order to be approved by the service I use? Maybe some certified plugin or something like that?
Thank you
