Hello,

I am trying to run C# to submit information into our API. However, we keep getting the following error: Message Returned:
Error:The remote server returned an error: (415) Unsupported Media Type.

Obviously we are missing something in the code. Any ideas? Of course, any confidential information is redacted 🙂

private string APIKey = "<HIDDEN>";
private string sNotesUrl = "https://api.hubapi.com/crm/v3/objects/contacts/";

private bool CreateCallNote(DateTime dActivityDate, string sDesc, string sSubject, string sPSID, string sDirection, string sDisp)
{

bool result = true;
// build json

ServiceLogger.Log(sLogFile, "Creating Temp Classes");
ServiceLogger.Log(sLogFile, "Creating Note Object:");
LeadNote NoteMain = new LeadNote();
ServiceLogger.Log(sLogFile, "Setting ID:" + skStudent);
NoteMain.Vendorid = Int32.Parse(skStudent);

ServiceLogger.Log(sLogFile, "Setting Description:");
NoteMain.description = sDesc;
ServiceLogger.Log(sLogFile, "Survcode:");
NoteMain.survcode = sSurvcode;
ServiceLogger.Log(sLogFile, "Disp Time:");
NoteMain.lastdispositioned = dActivityDate.ToShortDateString();

sURLOut = sNotesUrl;

ServiceLogger.Log(sLogFile, "Sending Up Json I hope:" + NoteMain.ToString());

string json = JsonConvert.SerializeObject(NoteMain, Formatting.None);
json="{\"properties\":" +json + "}";

ServiceLogger.Log(sLogFile, "Bare String:" + json);
// Transmist and get results
WebRequest objRequest;

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
objRequest = WebRequest.Create(sURLOut + sClientid + @"?hapikey=" + APIKey);

objRequest.Method = "PATCH";
objRequest.ContentLength = json.Length;
objRequest.ContentType = "application/json'";
StreamWriter myWriter = new StreamWriter(objRequest.GetRequestStream(), Encoding.ASCII);
myWriter.Write(json);

myWriter.Close();
WebResponse objResponse = objRequest.GetResponse();
StreamReader sr;
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
sr = new StreamReader(objResponse.GetResponseStream(), Encoding.ASCII);
string strresult = "";
strresult = sr.ReadToEnd();
ServiceLogger.Log(sLogFile, "Posted Response:" + strresult);
strresult = strresult.ToUpper();
strresult = strresult.Trim();

return (result);
}

public class LeadNote
{
public int Vendorid { get; set; }
public string survcode { get; set; }
public string description { get; set; }
public string lastdispositioned { get; set; }
}

json passed
{"properties":{"Vendorid":999999,"survcode":"TEST","description":"Testing Call Result","lastdispositioned":"4/19/2021"}}

your content-type is application/json but you are sending string data

string json = JsonConvert.SerializeObject(NoteMain, Formatting.None);

StreamWriter myWriter = new StreamWriter(objRequest.GetRequestStream(), Encoding.ASCII);
myWriter.Write(json);

in your code json variable is a string type, but API endpoint accept application/json format

Thank you! Turns out we also had to change to byte? Strange but thanks for your help!
