  OBIE Event Notification API Specification (Open Banking Read/Write Standard),
  documented as the "Events" product on developer.lloydsbanking.com/prod01/lbg/products.
spec_type: Webhooks
surface: OBIE Event Notifications
description: >-
  Lloyds Banking Group implements the OBIE Event Notification API, delivering
  resource-update and consent-lifecycle events to registered TPPs. It offers both a
  real-time push (callback URL) delivery mode and an aggregated polling mode, using
  the Security Event Token (RFC 8417) format signed as a JWT.
delivery_modes:
  - mode: real-time-push
    detail: >-
      TPP registers a callback URL (event-subscription); the ASPSP POSTs a signed
      SET (application/jwt) to that URL when an event occurs.
    resource: /event-subscriptions
  - mode: aggregated-polling
    detail: >-
      TPP polls the aggregated event endpoint to retrieve, acknowledge, and set the
      error state of outstanding event notifications.
    resource: /events
event_types:
  - urn: urn:uk:org:openbanking:events:resource-update
    description: A resource the TPP has access to has been updated.
  - urn: urn:uk:org:openbanking:events:consent-authorization-revoked
    description: A PSU or ASPSP has revoked a previously authorised consent.
  - urn: urn:uk:org:openbanking:events:account-access-consent-linked-account-update
    description: The set of accounts linked to an account-access consent has changed.
security:
  signing: Security Event Token (SET) delivered as a signed JWT (JWS).
  transport: mTLS + FAPI, same TPP onboarding as the Read/Write family.
notes: >-
  No standalone AsyncAPI document is published by Lloyds; this captures the webhook /
  event catalogue from the OBIE Event Notification standard the portal implements.
  Not fabricated - event types and delivery modes are the OBIE standard surface.
