Spotify Web API Console

Question

I am curious about how to get Json from a windows forms project and using a webBrowser control to simulate access to a spotify app. I know I need to pass a string of some kind such as clientid=.... etc

GET https://accounts.spotify.com/authorize/?client_id=5fe01282e44241328a84e7c5cc169165&response_type=code&redirect_uri=https%3A%2F%2Fexample.com%2Fcallback&scope=user-read-private%20user-read-email&state=34fFs29kd09

How would I accomplish this using the code above? Do I put it in string and send it off to a url using the webbrowser and some how get a response form the webpage???

Could someone show me some example to try and accomplish this? I am very confused.

I don't know how to use the "GET" command or any of those cURL commands. Another thing do I send the url to the webbrowser and have the response saved and try to seperate the Json that gets sent back?

Any help would be wonderful such as an explanation. Ultimately I am just trying to get information on how to access my APP I created in spotify and which url to use so that a user can login to my app and they get a token to use the webapi or so that I can use the web api.
