Which subscribed users receive a callback depends on the subscription's delivery mode (`permissionMode`). In both modes, only users in the lead's account (team) who have subscribed to the event type are considered. **Assignment-based delivery — `permissionMode: 0` (default)** A subscriber receives the callback only for leads assigned to them or that they administer: - If the lead is a **hidden lead**, only the **assigned agent** receives the notification. - Otherwise, the subscriber receives it if they are the **assigned agent** of the lead, or a **Company Owner** or **Company Admin**. - All other subscribers do **not** receive the notification. **Ownership-based delivery — `permissionMode: 1`** A subscriber receives the callback for any lead they manage, regardless of who it is assigned to: - Every assignment-based case above still applies (assigned agent, Company Owner / Company Admin). - In addition, the subscriber receives the callback for any lead within their **ownership scope** — a lead owned by their **team** or **office**, or **personally owned** by them — even if it is assigned to someone else. - Hidden leads are still delivered only to users who manage them. Ownership-based mode is intended for team/account-level integrations that must cover every lead in their scope, not only assigned leads. Set `permissionMode` when creating the subscription (POST /v1.0/webhook); it defaults to `0`, so existing subscriptions are unaffected. ### Delivery Timing Webhooks are typically delivered within **1 minute** of the event being triggered. During periods of high traffic, delivery may be delayed, but will always be sent within **5 minutes**.
