— Delete one subscription and stop its future notifications.

List Notifications — Read your private event notifications since a cursor. Save the returned cursor; follow hasMore. Includes publication, important changes, cancellation, withdrawal and restoration. History lasts 90 days.

Get Notification State — Atomically read all events followed by your active subscriptions and a fresh inbox cursor. Replace your local state with this snapshot when initializing or recovering from cursor-expired, then poll list_notifications.

Verify Webhook — Send a signed challenge to your endpoint. It must return JSON with the exact challenge. Successful verification enables notification delivery.

List Webhooks — List your endpoints and delivery health without returning signing secrets.
