Hi Someone want to send on my page a request with POST using the following parameters
1.orderId
2.amount

After I need to Return a JSON formatted as follows:

{"Success":0,"Message":"PUT A MESSAGE YOU WANT TO REACH THE CLIENT HERE","Status":0}

Success can only receive 1 or 0. it is 1 when you are sure the orderId correspond to the amount payed, otherwise return always 0
Message can be anything you want the client to receive
Status can vary from 0 to any number, given different stages of response you want to return.

Please can someone help me how to do this by an example in code .

Thanks!
