        StartCoroutine(GetReq(getURL));

    }

 

    IEnumerator GetReq(string url)

    {

        UnityWebRequest req = UnityWebRequest.Get(url);

        yield return req.SendWebRequest();//wait until request competed

 

        if (req.isNetworkError)//if the networkerror is true then, there is an error.

        {

            Debug.Log("Error While Sending: " + req.error);
