Webhooks
Webhook delivery format and HMAC signing — planned shape (v2 feature).
Webhook delivery is a v2 feature. This page documents the planned shape so integrators can prepare. Live delivery, retries, and the admin dashboard ship after the first paying webhook customer requests them.
Florida Tax Certificate API is an independent data platform and is not affiliated with the Florida Department of Revenue, any county tax collector or clerk of court, LienHub, RealAuction / RealTaxLien, or TaxCertSale.
Planned Shape
Webhooks deliver JSON POST requests to your registered endpoint with an X-FTC-Signature header containing an HMAC-SHA256 signature of the raw body using your endpoint's shared secret.
Subscribed event types (planned): certificate.added, certificate.redeemed, certificate_sale.scheduled, lands_available.added, saved_search.match.
Subscribe via the /admin/webhooks interface (admin-only in v1).
