呼び出し側

const string uri = "ttp://hogehoge.com/api?param1=";
string param1 = "value1";
param1 = WWW.EscapeURL (param1);
string url = uri + param1;
GameObject gameObj = new GameObject();
WebHttpRequest request = gameObj.AddComponent<WebHttpRequest>();
request.Exec (url);

呼び出し側で受信チェック

void Update ()
{
    if (request) {
        if (!request.GetBody ().Equals ("")) {
             // 処理
             request.Reset ();
        } else if (request.errorFlag) {
             request.errorFlag = false;
        }
    }
}
