Invoices support asynchronous notification callback when the status changes from initiated to paid.
To enable notification for an invoice, you’d provide a callback_url argument representing your website endpoint’s URL when creating a new invoice
For your server to receive a notification POST request from API including the invoice object as a JSON payload, your endpoint must be capable of receiving HTTP POST requests.
The returned Invoice object will be as aforementioned with the invoice details along with its payment history.
