Notifications
Notifications (a.k.a "Callbacks", "IPN") are used in 0xpay to alert users about events happenning to their merchants. Whenever something happens to your merchant, 0xpay will try to send a webhook to the Notifications URL that you've previously specified in merchant settings.
Webhooks require authorization on your side, in order to verify the validity of message received.
We guarantee that webhooks will come in described order, according to their tx status change.
For example: we won't send you a "Done" status webhook until you respond with success HTTP status to a "Pending" webhook that was sent earlier.
