A notification may consist of the following objects:

- `payment` - contains information about the created payment link,
- `transaction` - contains information about transactions if they were created for a given payment link,
- `notifyTransactionData` - specifies which exact transaction the notification refers to. This object is helpful when there is more than one payment method for a single payment.
