HTTP Request cookies


When I’m trying to send HTTP GET request to the website, it responds with 403 and “not logged in” page. If I paste the same request to the browser’s address bar, it successfully sends me JSON response. Not in request wizard, though.
I tried is to add session id (sid) from browser’s cookies to request as a header. It’s the only cookie required to keep the active session. But that didn’t help with request. Perhaps, I’m doing something wrong?


Request wizard setting example


I made the workaround by simply typing request link into browser’s address bar and that fixed the problem for GET requests. Of course, that’s not going to work with POST. I don’t even know if it’s possible to send cookies with http request.
Can anyone provide some more info about it?
