I am having trouble with deserialising a jsonstring. In my debug I get the error System.JSONException: Unknown field: MyJSON.number. As number is a reserved field in salesforce I replace it with numberRep. I dont get why I get this error.

webservice

  @HttpPost

     global static void createOpportunity() {

      RestRequest req = RestContext.request;  

         string a = req.requestBody.toString().remove('\');

         system.debug('DEB1: '+ a);         

          MyJSON tClass = MyJSON.parse(a);

         system.debug('DEB2: '+ tClass);

         system.debug('DEB3: '+ tClass.billing.address_1 );

         system.debug('DEB4: '+ tClass.cart_hash);

    }

Your class passes the wrong string to JSON.deserialize().

public static MyJSON parse(String json){

    String jsonReplace =  json.replace('"currency":', '"currencyRep":');

           jsonReplace =  jsonReplace.replace('"number"','"numberRep"');

    return (MyJSON) System.JSON.deserializeStrict(json, MyJSON.class);

You're transforming the string, but then not using the transformed version. Change the final line to

    return (MyJSON) System.JSON.deserializeStrict(jsonReplace, MyJSON.class);
