About
Reclaim Webhooks let downstream systems react when a meeting is booked, rescheduled, or cancelled through a Scheduling Link. Instead of polling Reclaim or manually updating a CRM after every booking, the receiving system gets a signed POST request with the meeting payload.
Webhooks support custom data passthrough (up to five data- query parameters), so booking attribution from a campaign or source can flow into the receiving workflow.
Top Benefits
- Booking events, in real time: Reclaim fires a POST request the moment a Scheduling Link meeting is created, rescheduled, or cancelled.
- Signed, verifiable payloads: Every request includes an x-reclaim-signature-256 header signed with your webhook secret, so receivers can verify authenticity.
- Custom data passthrough: Pass up to five data- parameters on a booking URL and receive them in the webhook payload for routing or attribution.
- Built for production systems: HTTPS endpoints only. Receivers should respond within 10 seconds and handle duplicate or out-of-order events safely.
What you can do
- Send POST requests when Scheduling Link meetings are created

How to connect
- Sign in to Reclaim and go to Team Settings → Webhook Settings.
- Click + New, enter a descriptive name, and add the receiving endpoint URL.
- Save or generate the webhook secret and store it securely.
- Open the Scheduling Link that should use the webhook, edit settings, and add the webhook configuration.
- Save the Scheduling Link. Reclaim will POST to the endpoint when meetings are booked, rescheduled, or cancelled.
Webhook support is available on Business and Enterprise plans. Endpoints must use https. Reclaim does not deliver to localhost or IP addresses. Receivers should respond within 10 seconds and treat events as idempotent.
