save and load json score to web/server

hello all, a somewhat newbie to unity, i'm looking to create a simple educational maze game for my workplace and all i wish to do is save the score to a location on the web or server. Presently it saves perfectly locally as a txt/json file. Any hints on adapting existing below script for save/load to web/url ? Ive been reading up on www functions and IEnumerators but i cant get it to work. thanks in advance.

     public Playerdata playerscore;
     private string scorepath;
 
 
     void Start () {
         scorepath = Path.Combine (Application.dataPath, "score.txt");
         //Save ();
     }
     
     // Update is called once per frame
     void Update () {
 
 
         if (Input.GetKey(KeyCode.S))
             Save ();
 
 
         if (Input.GetKey(KeyCode.L))
             Load ();
 
 
         
     }
     void Save () {
         string jsonscorekeep = JsonUtility.ToJson (playerscore);
         File.WriteAllText (scorepath,jsonscorekeep);
     }
 
 
     void Load () {
         string jsonscorekeep = File.ReadAllText (scorepath);
         JsonUtility.FromJsonOverwrite (jsonscorekeep, playerscore);
     }
 
 }
