The answers in this topic are all great  However i d like to propose another one  Most likely you have been given an api and want that into your c  project  Using Postman  you can setup and test the api call there and once it runs properly  you can simply click  Code  and the request that you have been working on  is written to a c  snippet  like this   var client   new RestClient  https   api XXXXX nl oauth token    client Timeout   -1  var request   new RestRequest Method POST   request AddHeader  Authorization    Basic   N2I1YTM4                                    jI0YzJhNDg     request AddHeader  Content-Type    application x-www-form-urlencoded    request AddHeader  Content-Type    application x-www-form-urlencoded    request AddParameter  grant type    password    request AddParameter  username    development XXXXXXXX-admin XXXXXXX XXXX    request AddParameter  password    XXXXXXXXXXXXX    IRestResponse response   client Execute request   Console WriteLine response Content     The code above depends on the nuget package RestSharp  which you can easily install
