Webhooks (Management)
Filing Updated Event
Sent when trigger_on_filing_updated is true and a filing you received was later re-typed or moved to another company. Same body as filing.processed, as the filing is now, plus 'changes'. Checked hourly over the last 30 days of deliveries (filings delivered since October 2026). Not billed.

Payload
Response
(Success) Acknowledge receipt.
Changes
Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
