Answer 1

If you want to add raw json data it is better to just pass it without WWWForm

public WWW POST()
{
    WWW www;
    Hashtable postHeader = new Hashtable();
    postHeader.Add("Content-Type", "application/json");

    // convert json string to byte
    var formData = System.Text.Encoding.UTF8.GetBytes(jsonStr);

    www = new WWW(POSTAddUserURL, formData, postHeader);
    StartCoroutine(WaitForRequest(www));
    return www;
}
