I have a JSON is structured as:

{
    "values": {
        "AppName": "Test001",
        "AppUser": "Testttt"
    },
    "consentAccepted": true,
    "consentToken": "adgrtztzEZKo3LD56Hjo8LiqeoQ2Z5 ik0loplr"
}

The above JSON works in https://web.postman.co/ and I get status as success.

I would like to try Unity's WebRequest with POST to fill in "AppName" and "AppUser" along with token. How do I achieve this?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;

public class SendData: MonoBehaviour {

void Update () {
        if (InputCompat.GetKeyDown (KeyCode.P)) {
            StartCoroutine ("FillAndSend");
        }
    }
public IEnumerator FillAndSend() {
        WWWForm form = new WWWForm ();

        form.AddField ("AppName", "Testttt");
        form.AddField ("AppUser", "Reinnn");

        UnityWebRequest www = UnityWebRequest.Post ("https://mywebsite.com/profile/MyApp", form);
        www.SetRequestHeader ("token", "tz677zuiuis2qEZKo3Lt kHluOGss");
        yield return www.SendWebRequest ();
        if (www.isNetworkError || www.isHttpError) {
            Debug.Log (www.error);
        } else {
            Debug.Log (www.downloadHandler.text);
        }
    }
}

I receive an error named as HTTP internal server error. What is wrong with it? Along with this I have to add a certain parameter that is given as:

formToken: MyApp

Looks like instead of a form you rather want to send a JSON string.

Something like

var json = "{\"values\": {\"AppName\":\"Test001\",\"AppUser\":\"Rein\"}, \"consentAccepted\":true, \"consentToken\":\"tz677zuiuis2qEZKo3Lt kHluOGss\"}";
var jsonBytes = Encoding.UTF8.GetBytes(json);

using (var www = new UnityWebRequest("https://mywebsite.com/profile/MyApp", "POST"))
{
    www.uploadHandler = new UploadHandlerRaw(jsonBytes);
    www.downloadHandler = new DownloadHandlerBuffer();
    www.SetRequestHeader("Content-Type", "application/json");
    www.SetRequestHeader("Accept", " text/plain");
    
    yield return www.SendWebRequest();

    if (www.isNetworkError || www.isHttpError)
    {
        Debug.Log(www.error);
    }
    else
    {
        Debug.Log(www.downloadHandler.text);
    }
}

It seems more to me an Authorization token problem. In order to try that, I created a request with these parameters as shown in the code, but I am getting a webpage in response it appears.

using System.Collections;

using UnityEngine;
using UnityEngine.Networking;

public class CustomRequest : MonoBehaviour {
        
        #region Private Field
        private string _url = "http://mywebsite.com/profile/MyApp";
        private string _jsonString = "{\"values\": {\"AppName\": \"Test001\",\"AppUser\": \"Rein\"} }";
        private string _token = "tz677zuiuis2qEZKo3Lt kHluOGss";
        #endregion Private Field
        
        #region MonoBehaviour Callback
        private void Start () {
            StartCoroutine ( SubmitRequest () );
        }
        #endregion MonoBehaviour Callback
        
        #region Coroutine Method
        private IEnumerator SubmitRequest () {
            using ( UnityWebRequest request = UnityWebRequest.Post ( _url, _jsonString ) ) {
                request.SetRequestHeader ( "Content-Type", "application/json" );
                request.SetRequestHeader ( "Authorization", "Bearer "   _token );

                yield return request.SendWebRequest ();

                if ( request.result == UnityWebRequest.Result.Success ) {
                    Debug.Log ( $"<color=lime>Response Date: {request.downloadHandler.text}</color>" );
                }
            }
