Hi, with next small problems.. I create ReceiverCallback, give PaymentCallback Dash is receive me address and add. info, request is 200 In callback give http://localhost:3002/api/payments/dash?action=PaymentCallback but when transaction is done, I didn't get callback request. 1. If I write server IP or domain name in callback, it's secr.? I remember, transfer is not secr. 2. How I can give callback another custom data? 3. Callback must run when get amount or confirm too? Thanks.
