# How to make Zapier ring your phone

Builders · https://lfg.gm/zapier-phone-alarm · Updated 2026-10-19

To make Zapier ring your phone, end your Zap with a **Webhooks by Zapier** action that sends a **POST** to the private link of an anything alarm in LFG Alarm. No key, no headers, no code: when the Zap runs, your phone rings like an alarm, and so do the friends you shared the alarm with. LFG Alarm is a social alarm clock for iPhone and Android, plus lfg.gm in a desktop browser, built for the alert you cannot sleep through when something really matters.

## Before you start

- **Get the LFG Alarm app on your phone** from Google Play or the App Store, and sign in. Zapier sets it off; the app is what rings.
- **A Zapier account on a plan that includes Webhooks by Zapier.** Zapier's help says Webhooks by Zapier and Filter steps are not on its Free plan; see Zapier's own plans for the current list.
- **A Zap with a trigger you care about**, such as a calendar event, a new payment or a form entry.

## Make the alarm

1. In LFG Alarm, on **Alarms**, tap **🔮 Anything**.
2. Name it for what it means, for example "VIP form" or "First sale". Nothing Zapier sends is shown on the ring screen, so the name is the message.
3. Pick a **Cooldown**, the alarm's quiet time after a ring: 1 minute to 1 hour. Calls inside it do not ring again, so a burst of Zap runs rings once.
4. Keep it private, or share it with the people who should hear it (an anything alarm is private or friends, never public), and tap **Arm it**.
5. On the link card, tap **Copy**. Tap **Test fire** once to hear it on your own phone.

## Add the step in Zapier

1. In the Zap editor, click **+** to add an action step and choose **Webhooks by Zapier**.
2. Under **Event**, choose **POST**, then click **Continue**.
3. In **URL**, paste the alarm's link. It looks like `https://api.lfg.gm/horn/` followed by 32 letters and digits.
4. **Payload Type** can stay as it is; LFG Alarm ignores the body.
5. In **Data**, add one row, for example `ring` on the left and `yes` on the right. Zapier's help says that if **Data** is left blank, every field from the previous step is sent; one dummy row keeps your customer or calendar details out of the request. Leave **Headers** and **Basic Auth** empty.
6. Test the step. Your phone should ring, and the response Zapier shows should include `"fired":true`.

## Add a filter so only what matters rings

An alarm that rings for everything stops being an alarm. Put a **Filter** step between the trigger and the webhook: click **+**, choose **Filter**, then pick a field, a rule and a value. The Zap only goes on to ring you when the condition is true. Use **+ And** to add more conditions, or an Or group for alternatives.

## Three Zaps that earn a ring

**The meeting you cannot be late for.** Priya runs a two-person design studio and loses track of time when she is deep in a file. Her Zap uses her calendar's event start trigger, set a few minutes before each event, and a filter that only passes events whose title contains "Client". The anything alarm "Client call" is shared with her co-founder, so both phones ring before the call starts and neither of them joins late.

**The first sale.** Theo has spent six months on a small app and launches on a Tuesday. His Zap watches Stripe for a new payment and POSTs to an alarm called "First sale". When the first one lands at 02:40, his phone rings and so does his brother's, who helped build it. After launch week he adds a filter for payments over $500, so only the big ones ring. Through a busy hour, a 1 hour cooldown means the alarm rings once, not twenty times.

**The client who gets an answer tonight.** Lena runs a small agency. Her enquiry form feeds a Zap with a filter on the email field: it only goes on if the address ends in one of three VIP clients' domains. Every other enquiry goes to the shared inbox as usual. A VIP enquiry rings Lena and her account manager, who both joined the "VIP form" alarm.

## How it rings

On Android an anything alarm rings full screen, like an alarm. On iPhone it arrives as a time-sensitive alert with the alarm's sound, 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. See [alarms on your laptop](https://lfg.gm/alarms-on-your-laptop).

## If it does not work

- **Zapier shows 429.** The alarm is inside its quiet time, so it already rang recently. That is the cooldown doing its job.
- **Zapier shows 409.** The alarm is switched off. Switch it on in the app.
- **Zapier shows 404.** The link is wrong, the alarm was deleted, or someone tapped **New URL**. Copy the link again.
- **Nothing rings and there is no answer from LFG Alarm.** Check that **Event** is **POST**; a GET does nothing.
- **The Zap ran but your iPhone stayed quiet.** Check the ringer switch and that LFG Alarm notifications are allowed.

## Questions

### Do I need an LFG Alarm key or an API token for Zapier?
No. The link is all it needs. That also means anyone who has it can ring the alarm, so treat it like a password, keep it out of shared Zaps you do not control, and tap **New URL** on the alarm's page if it leaks.

### Can one Zap ring several people?
Yes. Share the anything alarm with them and everyone who joined is rung by the same POST.

### Can the ring screen show the Stripe amount or the event title?
No. LFG Alarm ignores whatever Zapier sends. Name the alarm for what it means, and make separate alarms for things that need different reactions.

### Can my AI agent make the alarm for me?
Yes. Through the [LFG Alarm connector](https://lfg.gm/agents), ask for an anything alarm, private or for friends, and it hands back the link to paste into Zapier.
