Make an anything alarm
- On Alarms, tap 🔮 Anything.
- Under Cooldown, pick 1m, 5m, 10m, 30m or 1h: the time after a ring during which more calls are ignored. 10 minutes is the default.
- Choose who it is for (private or friends) and tap Arm it.
- The horn card shows the link, with Copy, Test fire (rings only your phone), New URL (the old one stops working) and What's a webhook?.
Ring it
Send an HTTP POST request to the link:
curl -X POST https://example.com/lfg-webhook-link
Replace the placeholder with your own link. Opening the link in a browser does nothing, and nothing you send is shown: it just rings.
Examples
- Your site is down. Point a site monitor's "down" alert at the link, private, 30m cooldown, so one outage rings once, not every minute.
- A long job is done. Add the curl line to the end of a build or a training script and go to sleep.
make release && curl -X POST <your link>. - A shared house alarm. An IFTTT applet that fires when the doorbell camera sees a parcel, shared with your flatmates as a friends alarm.
Good to know
- Guard the link like a password. If it leaks, tap New URL, and update whatever calls it.
- Anything alarms are never public, and riders cannot keep a copy if you delete one.
- Deleted, the link answers "not found"; switched off, it says it is switched off, so a script you are debugging tells you the truth.
- Once a second person rides it, the link is sealed too: New URL no longer works on it.
- On Android it rings full screen, even on Do Not Disturb. On iPhone it arrives as a time-sensitive alert with the alarm's own sound, which can come through Focus but respects the silent switch, so keep the ringer on.
