public class goLevel : MonoBehaviour {
	//With the @ before the string, we can split a long string in many lines without getting errors
	private string json = @"{

		//Our custom Headers
		Dictionary<string,string> parameters = new Dictionary<string, string>();
		//Encode the access and secret keys
		accessToken = System.Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes( myAccessKey + ":" + mySecretKey));
		//Add the custom headers
		parameters.Add( "Authorization", "Basic " + accessToken);
		parameters.Add( "Content-Type", "application/json" );
		parameters.Add( "AnotherHeader", "AnotherData" );

		//Replace single ' for double " 
		//This is usefull if we have a big json object, is more easy to replace in another editor the double quote by singles one
		json = json.Replace("'", "\"");
		//Encode the JSON string into a bytes
		byte[] postData = System.Text.Encoding.UTF8.GetBytes (json);
		//Now we call a new WWW request
		WWW www = new WWW(URL, postData, parameters);
		//And we start a new co routine in Unity and wait for the response.
		StartCoroutine(WaitForRequest(www));

	//Wait for the www Request
