# Time To Live (TTL) improvements for webhook events

BILL now maintains a 90-day event history for each subscription. You can get the list of event notifications sent to you for a subscription with `GET /v3/events/subscription/{subscription_id}`. You can now get the list of events for the last 90 days.
