i getting error

the remote server returned error: (400) bad request.

please help

here's usual strategy posting external apis, hope helps

using (var http = new httpclient()) {     // define authorization headers here, if     // http.defaultrequestheaders.add("authorization", authorizationheadervalue);      var data = new modeltype {         name = namevalue,         email = emailvalue     };      var content = new stringcontent(jsonconvert.serializeobject(data));     content.headers.contenttype = new mediatypeheadervalue("application/json");      var request = http.postasync("[api url here]", content);      var response = request.result.content.readasstringasync().result;      return jsonconvert.deserializeobject<responsemodeltype>(response); } 

the request can awaited, instead of calling .result directly.

to use approach need create c# model based on response json structure. oftentimes use http://json2csharp.com/, provide typical json response endpoint i'm interested in, , c# model gets generated me automatically.
