Azure RESTful API rejecting my post requests with bad request

  android, azure, c#, post, rest

I am pretty new to APIs and am struggling with POST requests. Specifically, I need help putting my headers in the right places. I’ve been unable to use fiddler to look at my request because I am running it through an android emulator and it gets complicated, but I have been able to extract the request from debugging the code. I am getting a bad request error right now, but I am also constantly being told I am using the wrong header in the wrong place when I try to experiment.

                string apiPath = ApiPath.Trim();
                Dictionary<string, string> headers = new Dictionary<string, string>();
                //headers.Add("content-type", "application/json; odata=verbos");
                //headers.Add("content-type", "application/json");
                headers.Add("Accept-Encoding", "gzip, deflate, br");
                headers.Add("Accept", "*/*");
                StringContent stringContent = new StringContent(JsonConvert.SerializeObject(parameters), Encoding.UTF8, "application/json");
                stringContent.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");
                //HttpContent content = new HttpContent;
                //Dictionary<string, string> headers = new Dictionary<string, string>();
                HttpResponseMessage token = await client.InvokeApiAsync(apiPath, stringContent, HttpMethod.Post,headers,null );
            catch (MobileServiceInvalidOperationException ex)
                string RequestDump = ex.Request.ToString();
                string RequestDump2 = ex.Request.RequestUri.ToString();
                string RequestDump3 = ex.Request.Headers.ToString();
                string RequestDump4 = ex.Request.Content.Headers.ToString();
                return null;

Here is what I got from fiddler when executing the same post on my API while running on my local.

I am tearing my hair out. Not sure what goes where. Also, is the "entity" object a different name for the "content" object?
