HttpClient.PostAsync causes 400 error when passing JSON to API

Question

I am trying to pass some data in JSON format to the Bugzilla API but am getting a 400 response. I am using Netwonsoft.Json to generate the JSON and it from what I can tell it is generated fine so I am not really sure what is causing the 400 error.

Code:

var Client = new HttpClient();

Dictionary <string, string> BugData = new Dictionary<string, string>
{
    { "Bugzilla_api_key", "Removed for scurity" },
    { "product", "Test" },
    { "component", "Test Component" },
    { "version", "unspecified" },
    { "summary", "Basic API Test" },
    { "description", "A basic API test" }
};

string Json = JsonConvert.SerializeObject(BugData, Formatting.Indented);

var Response = await Client.PostAsync("http://bugzillaaddress/rest/bug", new StringContent(Json, Encoding.UTF8, "application/json"));

The JSON it appears to be generating is:

{
    "Bugzilla_api_key": "Removed for security",
    "product": "Test",
    "component": "Test Component",
    "version": "unspecified",
    "summary": "Basic API Test",
    "description": "A basic API test"
} 

Any ideas what I am doing wrong here?

Full Error response:

{StatusCode: 400, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
  Connection: close
  Date: Fri, 29 Jan 2016 13:36:01 GMT
  ETag: IzeHlNLRTewC8+btLeGxXA

  X-content-type-options: nosniff
  X-frame-options: SAMEORIGIN
  X-xss-protection: 1; mode=block
  Content-Length: 11
  Content-Type: text/html
}}

This is what Fiddler sees:

POST http://bugzilla-tools/rest/bug HTTP/1.1 Content-Type: application/json; charset=utf-8 Connection: Keep-Alive Content-Length: 193 Host: bugzilla-tools

{"Bugzilla_api_key":"Removed for security","product":"Test","component":"Test Component","version":"unspecified","summary":"Basic API Test","description":"A basic API test"}

Edit: Response from Bugzilla Team

I am apparently not passing an Accept header in with my request which they require. If I add an accept header I should be good. Anyone know how to do that? (I am looking right now and playing with things but if someone has code I can copy and past to end 4 days of fighting with this API that would be great!)

I managed to get onto my PC. Here is some sample code.

var Client = new HttpClient();

Dictionary <string, string> BugData = new Dictionary<string, string>
{
    { "Bugzilla_api_key", "Removed for scurity" },
    { "product", "Test" },
    { "component", "Test Component" },
    { "version", "unspecified" },
    { "summary", "Basic API Test" },
    { "description", "A basic API test" }
};

string Json = JsonConvert.SerializeObject(BugData, Formatting.Indented);

var request = new HttpRequestMessage(HttpMethod.Post, "http://bugzillaaddress/rest/bug");

request.Content = new StringContent(Json, Encoding.UTF8, "application/json")
request.Headers.Add("Accept", "application/json");

var Response = await Client.SendAsync(request);

Edit

I actually noticed that you can do this using PostAsync as well.

Change it to this.

var Client = new HttpClient();

Dictionary <string, string> BugData = new Dictionary<string, string>
{
    { "Bugzilla_api_key", "Removed for scurity" },
    { "product", "Test" },
    { "component", "Test Component" },
    { "version", "unspecified" },
    { "summary", "Basic API Test" },
    { "description", "A basic API test" }
};

string Json = JsonConvert.SerializeObject(BugData, Formatting.Indented);

var content = new StringContent(Json, Encoding.UTF8, "application/json");
content.Headers.Add("Accept", "application/json");

var Response = await Client.PostAsync("http://bugzillaaddress/rest/bug", content);
