My webhook action isn't firing

1. Is the rule enabled? Toggle it on under Rules.
2. Is the threshold actually crossed? Check the device's live value.
3. Cooldown — after a fire, the rule waits cooldownMinutes before firing again.
4. Monthly action quota — if you've hit max_action_fires_per_month, actions stop until next month. Check Quota & limits.
5. Allowed actions — webhook/MQTT actions require a plan that permits them.
6. Endpoint — we sign requests with X-Synacl-Signature: sha256=…; verify your endpoint returns 2xx. Repeated failures appear as action/failed events.

See rule action: webhook and verifying webhook signatures.
