Callback functions

Callbacks are functions that you can provide to a method in the SDK which will give you feedback when an event occurs.

They can be useful when you want to record data & attributes at a particular stage of a transaction.

Callback	Description
`onSuccess`	Invoked when the transaction, claim (when applicable) & payment is successful.Warning: This callback will not be invoked if the user closes the modal before a successful transaction. You can use the invoiceCompleted Webhook to track the transaction outcome.
`onFailure`	Invoked when the payment has failed.
`onCancel`	Invoked when the payment has been rejected.
`onClosed`	Invoked when the pop-up window has been closed by the user before approving or rejecting the payment.
