Posting Unity Data to PowerBI API

Question

I am trying to use a PowerBI API which saves Unity data. I know there are a lot of solved questions online for Unity and APIs with Web Requests but I have scoured the internet and I think it might be due to the PowerBI API permissions. My client REALLY wants to use Azure/PowerBI for this and not Unity Cloud or Google so that is why I am using it. In order for Unity to write data to the API I have been trying to use the UnityWebRequest. However, I have gotten many errors. I have been testing my API with Postman and Powershell. I am able to "POST" but I can't "GET", "PUT", or anything else and get a 404 error. I am hoping this won't be an issue because I just want to post anyway. I don't seem to be able to change the API permissions through PowerBI so that is a constraint.

I created a PowerBI streaming datasource API with a URL and desired data in the following format:

[ { "Variable 1" :98.6, "Variable 2" :98.6 } ]

Here are two different ways I have tried to code this:

using System;
using System.Collections;
using System.Collections.Specialized;
using System.Diagnostics;

using System.Text;
using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.UI;

public class PlayerData
    {
        public int Experience;
        public int Confidence;
    }
 public void StartPost()
    {
        StartCoroutine(PostData());
    }

    IEnumerator PostData()
    {
        //fills player data class with users metrics
        PlayerData player = new PlayerData();
        player.Experience = 3;
        player.Confidence = 5;
        string URL = "https://blahblahblah";
        string jsonData = JsonUtility.ToJson(player);
        UnityWebRequest request = new UnityWebRequest.Post(URL, jsonData);
        yield return request.SendWebRequest();

        if (request.error != null)
        {
            UnityEngine.Debug.Log("Error: " + request.error);
        }
        else

        {
            UnityEngine.Debug.Log("Status Code: " + request.responseCode);
        }
    }

This gives me an error of: The type name 'Post' does not exist in the type 'UnityWebRequest'.

The other way I do it is to change PostData to use UploadHandlerRaw:

    IEnumerator PostData()
    {
        //fills player data class with users metrics
        PlayerData player = new PlayerData();
        player.Experience = 3;
        player.Confidence = 5;

        string jsonData = JsonUtility.ToJson(player);
        byte[] bodyRaw = Encoding.UTF8.GetBytes(jsonData);
        UnityWebRequest request = new UnityWebRequest(URL, "POST");
        request.uploadHandler = (UploadHandler)new UploadHandlerRaw(bodyRaw);
        request.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();
        yield return request.SendWebRequest();

        if (request.error != null)
        {
            UnityEngine.Debug.Log("Error: " + request.error);
        }
        else

        {
            UnityEngine.Debug.Log("Status Code: " + request.responseCode);
        }
    }

This code gives me a 400 Bad Request message with the full stack trace:

UPDATE: I have tried deleting the "new" from the UnityWebRequest.POST line and I now get a 500 Internal Server Error.

I have also tried writing out the string and passing it directly to Post but this still doesn't work. Any help would be greatly appreciated.
