Paste this into your scheduling tool's "on cancellation" webhook setting.
SlotRevive requires every cancellation webhook to carry a valid
X-Webhook-Signature header — an HMAC-SHA256 of the raw
request body, computed with this secret
(hex["sha256=" + HMAC_SHA256(secret, rawBody)]).
Requests without a valid signature are rejected with 401.

⚠️ Keep this secret private — anyone who has it (together with your webhook URL) can forge cancellation events for your business. Configure it in your scheduling tool's webhook signing settings; never share it, paste it into other websites, or put it in URLs.
Connect Calendly and SlotRevive automatically detects cancelled appointments — no webhook URL to paste. Rescheduled events are never treated as cancellations.
Acuity users: paste the Webhook URL below into Acuity's webhook settings instead.
Configure how SlotRevive handles incoming claim requests.
One customer per line: Name, Phone, Services, Priority. Phone can be any common format — it will be normalized to E.164. Duplicate phones are skipped (never double-added). Invalid rows are reported, not discarded.
