Callback is an http post request with json encoded body. Callbacks are sent when a transaction hits the network and with each subsequent block. To stop sending callbacks, send a json response with content of {"stop": true}. If no callback stop response has been received, callbacks will stop being sent after three hours from the moment the transaction hits the network. IP addresses, from which callbacks are sent, are available from the dns request of api server domain "api.greencryptopay.com". Make sure your firewall settings allow you to recieve callbacks.

callback_secret will be sent in a callback data to confirm that the callback was sent by our service
