# Overview

The Event Notification resource is used by a ASPSP to notify a TPP of an event.

This resource description should be read in conjunction with a compatible Real Time Event Notification Profile.

# Endpoints

An ASPSP will send event notifications to a TPP using the event-notification resource.

# Endpoints

Resource HTTP Operation Endpoint Mandatory ? Scope Grant Type Message Signing Idempotency Key Request Object Response Object
event-notification POST POST /event-notifications Optional n/a n/a Signed Request No OBEventNotification1

Notes:

  • A TPP must make available an event notification endpoint to receive event notifications.
  • A TPP must acknowledge an event notification with a 202 HTTP response and include the provided x-fapi-interaction-id.

# POST /event-notifications

The API endpoint allows the ASPSP to send an event-notification resource to a TPP.

# Transport Level Security

TPP hosted endpoints must be protected using TLS 1.2, as per the FAPI R/W specification.

TPP hosted endpoints must be protected using a network certificate issued by a Trust Anchor supported by the ASPSP.

MA-TLS is not applicable to TPP hosted endpoints.

# Data Model

# Event Notification - Request

The OBEventNotification2 object will be used for a call to:

  • POST /event-notifications

Note, the OBEventNotification2 object is aligned with the Security Event Token (https://tools.ietf.org/html/rfc8417). It acts as a wrapper for events contained within the events claim.

# UML Diagram

OBEventNotification2

# Notes

  • The rid, rty and rlk claims are prefixed with the OB namespace http://openbanking.org.uk in the data model. The namespace has been removed from the diagram for clarity.

# Event Notification Retry Policy

# ASPSP

An ASPSP's Event Notification Retry Policy defines behaviour when an event notification is unacknowledged or the ASPSP receives a 5xx error.

  • An Event Notification Retry Policy must define an Exponential Backoff Policy to calculate the Retry Time Interval.
  • An Event Notification Retry Policy must define the Maximum Number of Retries an ASPSP will make before declaring the TPP Event Notification endpoint unresponsive and ceasing further attempts.
  • An Event Notification Retry Policy must define the Maximum Time Interval for Retries, after which an ASPSP will declare the TPP Event Notification endpoint unresponsive and cease further attempts.

# TPP

A TPP may make GET requests for its resources if its /event-notifications endpoint was unavailable for the Maximum Time Interval for Retries, as defined in an ASPSP's Event Notification Retry Policy.

# Usage Examples

# Send Event Notification - Resource Update

# POST Event Notification Request

POST /event-notifications HTTP/1.1
