# How to make any app, script or feed ring your phone Builders · https://lfg.gm/webhook-alarm · Updated 2026-10-16 To make any app, script or feed ring your phone, give it the private link of an anything alarm in LFG Alarm: anything that can send an HTTP POST request to that link rings you like an alarm, and rings the friends you shared it with too. LFG Alarm is a social alarm clock for iPhone and Android, and lfg.gm in a desktop browser. An anything alarm (a webhook alarm) is how a site monitor, a cron job, a trading bot, Zapier, Make, IFTTT or a phone shortcut gets a human out of bed. ## The problem: your code can notice, but it cannot wake you Builders already have scripts that know when something is wrong. A health check sees the API return 500s. A bot sees its order filled. A nightly job sees the backup failed. What they usually do with that knowledge is send an email, a Slack message or a push notification, and all of those wait politely until morning. Full on-call tools solve this for companies with rotations and escalation policies. A solo founder, a two-person team or someone running a side project usually needs something smaller: one link that makes one or two phones ring when the script says so. ## Three builders, three alarms **The site that goes down at 3am.** Maya runs a small shop on her own. She already uses a site monitor that can call a webhook when the site stops answering. She makes an anything alarm called "Shop down" with a 30 minute cooldown, shares it with her co-founder, and pastes the link into the monitor's alert settings. The first outage at 03:10 rings both phones. She fixes the expired certificate; he goes back to sleep once she posts in their chat. **The bot that needs a human.** Ben runs his own trading script. It places orders on its own, but when a large order fills he wants to look at the position himself before the next session. He adds one line to the script's fill handler that POSTs to his alarm's link. LFG Alarm does not trade and sees nothing the script sends; it just rings, and Ben opens his own dashboard to check. **The deploy that should not fail quietly.** A three-person team adds a final step to their CI pipeline: if the production deploy fails, call the alarm link. The alarm is shared with all three. A 10 minute cooldown means a pipeline that retries five times rings once. ## The integration is one request ```bash curl -X POST https://example.com/lfg-webhook-link ``` Replace the placeholder with your own link from the app. In a script, the same idea is a single POST when your condition is true, for example the last line of a health check that has just failed. That is the whole integration. ## How the link works - **Send an HTTP POST request and it rings.** Opening the link in a browser does nothing. - **Nothing you send is shown.** Whatever is in the request appears nowhere. It just rings, so name the alarm for what it means ("Shop down", "Big fill"). - **A cooldown stops loops.** Pick 1, 5, 10, 30 or 60 minutes (10 is the default). Calls during the cooldown after a ring are ignored, so a bot stuck in a loop cannot ring you all night. - **Guard it like a password.** If the link leaks, tap **New URL** and the old one stops working. - **Never public.** An anything alarm is private, or shared with friends you choose. Only you know what sets it off. - **Clear answers.** A deleted alarm's link answers "not found"; a switched-off alarm answers that it is switched off. ## How it rings On Android an anything alarm rings full screen, even on Do Not Disturb. On iPhone it arrives as a time-sensitive alert with the alarm's own sound; it can come through Focus but respects the silent switch, so keep the ringer on if you depend on it overnight. With an lfg.gm tab open on an awake laptop, it rings there too, for up to ten minutes. See [alarms on your laptop](https://lfg.gm/alarms-on-your-laptop). ## Make it in the app 1. On **Alarms**, tap **🔮 Anything**. 2. Under **Cooldown**, pick **1m**, **5m**, **10m**, **30m** or **1h**. 3. Choose who it is for, private or friends, and tap **Arm it**. 4. On the link card, tap **Copy**, then **Test fire** to ring only your own phone and check it works. 5. Paste the link into your monitor, script, Zap or shortcut. Your AI agent can make one too: ask for an anything alarm, private or for friends, and it hands you the link to paste into your monitor, script or Zap. ## Set one up with no code Under the link, **What's a webhook?** explains it for people who have never used one, with three everyday ideas: ring when an app you use says so (Zapier, Make or IFTTT), a one-tap button on your phone for the crew ("we're outside", "the game's on"), and ring when your site goes down or a big sale lands. It also has a prompt to copy into ChatGPT, Claude, Grok or any AI. The prompt explains how the link works with a placeholder in place of your real link, then asks the AI to suggest ideas and walk you through a free, no-code tool step by step. You paste your real link into the tool yourself. ## Common mistakes - **Testing by opening the link in a browser.** That sends a GET request and does nothing. Use **Test fire**, or a POST. - **A cooldown that is too short for a flapping service.** If your site goes up and down every minute, a 1 minute cooldown rings every minute. Use 30 minutes. - **Pasting the link into a public repository.** Keep it in a secret or environment setting, and tap **New URL** if it ever leaks. ## Questions ### What happens if I delete the alarm? The link stops working: a call to a deleted alarm's link gets a "not found" answer. A switched-off alarm answers that it is switched off. ### Can a stranger ring my phone with it? Only someone who has the link. Keep it private, and change it with **New URL** if it leaks. ### Is this an on-call tool? No. It has no schedules or escalation. It rings the phones on the alarm. See [alert apps compared](https://lfg.gm/alert-apps-compared). ### Can my AI agent make one? Not yet. Make it in the app, then give the link to whatever should ring it. ## Sources and further reading - [Anything alarms](https://lfg.gm/wiki/anything-alarms) - [Alarms on your laptop](https://lfg.gm/alarms-on-your-laptop) - [Alert apps compared](https://lfg.gm/alert-apps-compared) - See also [an alarm for when someone posts](https://lfg.gm/alarm-when-someone-posts) and the [developers page](https://lfg.gm/developers) ## Keep exploring - [Website change alerts: how to get an alarm when something happens online](https://lfg.gm/alert-when-something-happens-online.md): Point a website change monitor, an uptime monitor, Zapier, IFTTT, GitHub Actions or a cron script at an anything alarm’s link and it rings your phone. - [How to get an alarm when someone posts on X](https://lfg.gm/alarm-when-someone-posts.md): Describe the post you are waiting for; Rocco rings you when it lands. - [How creators can catch a trend before it peaks](https://lfg.gm/creator-trend-alarms.md): Alarms that ring when the accounts, channels and feeds you trust move first. - [The fastest way to get your whole family's attention](https://lfg.gm/family-alert.md): One alarm the whole family joins, so every phone rings out loud at once, with your note on the screen. ## About LFG Alarm LFG Alarm is a social alarm clock for iPhone, iPad and Android.
