Sending a post request with body and a header in it with UnityWebRequest

I am trying to send a post request to an Api called Paycell Api. I dont need to authenticate for testing the request. When I send the request with PostMan, it returns 200 OK. Here is the exact request.

{ "msisdn": "5380521479", "requestHeader": { "applicationName": "PAYCELLTEST", "applicationPwd": "PaycellTestPassword", "clientIPAddress": "10.252.187.81", "transactionDateTime": "20160309084056197", "transactionId": "12345678901234567893" }
} 

When ı try to implement it to C# it returns 406 Not Acceptable. Here is how it looks

using Newtonsoft.Json;
using System.Collections;
using TMPro;
using UnityEngine;
using UnityEngine.Networking;
public class GetCardsRequest : MonoBehaviour
{ private string url = ""; public void GetCards() { StartCoroutine(MakeCardRequest()); } IEnumerator MakeCardRequest() { var bodyRequest = new GetCardRequest() { requestHeader = new RequestHeader() { applicationName = "PORTALTEST", applicationPwd = "ZDyXmMLWE2z7OzJU", clientIPAddress = "10.252.187.81", transactionDateTime = "20160309084056197", transactionId = "12345678901234567893" }, msisdn = "5380521479" }; bodyRequest.requestHeader = new RequestHeader(); var body = JsonConvert.SerializeObject(bodyRequest); UnityWebRequest request = UnityWebRequest.Post(url, body); request.SetRequestHeader("Content-Type", "application/json"); request.SetRequestHeader("Accept", "text/csv"); yield return request.SendWebRequest(); if (request.result == UnityWebRequest.Result.ConnectionError || request.result == UnityWebRequest.Result.ProtocolError) { Debug.Log(request.error); } else { //var cardName = JsonConvert.DeserializeObject<GetCardResponse>(request.downloadHandler.text); } }
}

İf I delete the part

request.SetRequestHeader("Content-Type", "application/json");
request.SetRequestHeader("Accept", "text/csv");

It returns 415 Unsupported Media Type Error.

How can I send this request, please help me.

Here's the documentation of the API, it shows an example request.Paycell API

And here is how I implemented GetCardRequest

// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
public class RequestHeader
{ public string applicationName { get; set; } public string applicationPwd { get; set; } public string clientIPAddress { get; set; } public string transactionDateTime { get; set; } public string transactionId { get; set; }
}
public class GetCardRequest
{ public string msisdn { get; set; } public RequestHeader requestHeader { get; set; }
}

Now with your code the first main issue is mot probably that your JSON is always empty fields.

you are doing

bodyRequest.requestHeader = new RequestHeader();

which erases all the previously filled in values

and then as mentioned before another thing to try might be rather using

IEnumerator MakeCardRequest()
{ var bodyRequest = new GetCardRequest() { requestHeader = new RequestHeader() { applicationName = "PORTALTEST", applicationPwd = "ZDyXmMLWE2z7OzJU", clientIPAddress = "10.252.187.81", transactionDateTime = "20160309084056197", transactionId = "12345678901234567893" }, msisdn = "5380521479" }; var body = JsonConvert.SerializeObject(bodyRequest); var bytes = Encoding.UTF8.GetBytes(body); using(var request = new UnityWebRequest(url, "POST")) { request.uploadHandler = (UploadHandler) new UploadHandlerRaw(data); request.downloadHandler = (DownloadHandler) new DownloadHandlerBuffer(); request.SetRequestHeader("Content-Type", "application/json"); yield return request.SendWebRequest(); if (request.result != UnityWebRequest.Result.Success) { Debug.Log(request.error); } else { var cardName = JsonConvert.DeserializeObject<GetCardResponse>(request.downloadHandler.text); Debug.Log(cardName); } }
}
