//! Notification objects. Those objects will be send on notify_url if was given.
//!
//! To enable notifications for a specific payment, specify the notifyUrl
//! parameter in the payment form. Each payment can receive a different URL to
//! which notifications will be sent.
//!
//! Every notification is sent asynchronously. After your system receives a
//! notification with the status COMPLETED, instruct it to ignore any further
//! notifications.
//!
//! After sending a notification, PayU system requires a 200 HTTP status code in
//! response. If it receives a different status code, it will resend the
//! notification. Your system should also take account of situations where a
//! notification is sent several times with the same status. For each repeated
//! notification, response with code 200 should be sent as well.
//!
//! To ensure trusted communication between PayU and your shop, you must verify
//! the signature value available in the OpenPayu-Signature header each time
//! your system receives any notification from a PayU server. Refer to the
//! Verification of notifications signature for more information.
//!
//! Notifications are sent for orders in the following statuses: PENDING,
//! WaitingForConfirmation, COMPLETED, CANCELED.
//!
//! Note: if you filter IP addresses, remember to allow IPs used by PayU to send
//! the notifications. These are:
//!
//! ### PRODUCTION
//!
//! > 185.68.12.10, 185.68.12.11, 185.68.12.12, 185.68.12.26, 185.68.12.27,
//! > 185.68.12.28
//!
//! ### SANDBOX
//!
//! > 185.68.14.10, 185.68.14.11, 185.68.14.12, 185.68.14.26, 185.68.14.27,
//! > 185.68.14.28
//!
//! ## Payment lifecycle
//!
//! You can configure a separate auto-receive / automatic collection parameter
//! for each payment method via the Management Panel.
//!
//! By default, auto-receive is enabled. The basic payment sequence is as
//! follows:
//!
//! 1) Each successfully authorized payment for an order is captured.
//! 2) The buyer is charged with the order amount.
//! 3) The shop balance is increased by the order amount.
//! 4) PayU calculates its commission to the order.
//!
//! If the auto-receive is turned off, you should capture each order using a PUT
//! method (Order capture) or cancel using DELETE method (Cancellation).
//!
//! If no such action is taken the order is auto-canceled. Automatic
//! cancellation occurs after a number of days indicated for the payment method.
//!
