The Real Time Event Notification API Profile describes the flows common functionality for the Real Time Event Notification API, which allows ASPSPs to notify an AISP/ PISP that an event has occurred.
The AISP/ PISP may optionally initiate a client credential grant to retrieve the resource using the details contained in the event notification.
