What it does
Get notified the instant something happens, instead of polling the API. Subscribe an HTTPS endpoint at Settings → Webhooks and ChurchLinker will POST a signed JSON payload to it whenever a relevant event fires.
Six events to subscribe to: person.created, person.updated, event.created, event.attendance.recorded, donation.created, group.created. Pick any combination per subscription. Every delivery carries an HMAC-SHA256 signature with a timestamp prefix so you can verify authenticity and defeat replay attacks.
Retries are built in: three attempts with 5-second and 30-second backoff, with a per-attempt audit row visible in the dashboard. A Test Fire button next to every subscription POSTs a synthetic event to your endpoint so you can verify your signature-verification code before any real event depends on it.
Bundled with API access. Same plan gating, same £19/mo add-on route for Sprout, Grow and Thrive churches.
