Webhooks
Rotate a subscription's signing secret
Mints a new signing secret for one of your webhook subscriptions and returns it exactly once (companion to the disclose-once policy on subscribe). Identify the subscription by id or by target_url (+ optional event, default lead.created); always scoped to the API key’s organization. Rotation takes effect immediately — update your receiver first, or tolerate a brief verification-failure window.
