# How to make a Make scenario ring your phone

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

To make a Make scenario ring your phone, add the **HTTP** app's **Make a request** module at the end of the scenario, set **Method** to **POST** and paste the private link of an anything alarm in LFG Alarm as the **URL**. When the scenario reaches that module, 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. Make sets it off; the app is what rings.
- **A Make account and a scenario** with a trigger module you care about, such as a calendar, a payment app or a form.

## Make the alarm

1. In LFG Alarm, on **Alarms**, tap **🔮 Anything**.
2. Name it for what it means, for example "Big order" or "Board call". Nothing Make 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 scenario that processes ten bundles at once 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 HTTP module

1. In the scenario editor, add a module after your trigger and choose the **HTTP** app, then **Make a request**.
2. **URL:** paste the alarm's link. It looks like `https://api.lfg.gm/horn/` followed by 32 letters and digits.
3. **Method:** **POST**.
4. Leave **Authentication type**, **Headers** and **Query parameters** empty, and send no body. LFG Alarm ignores the body, so there is no reason to pass your customer or calendar data along.
5. Click **Run once** and fire the trigger. Your phone should ring, and the module's output should include `"fired":true`.

## Add a filter so only what matters rings

An alarm that rings for everything stops being an alarm. Make lets you put a filter on the line between two modules: click the line between the trigger and the HTTP module, give the filter a name, and set a condition from an operand, an operator and a value. Only bundles that pass the condition reach the HTTP module and ring you.

## Three scenarios that earn a ring

**The board call at 6am.** Jun is a founder in Singapore with investors in New York, so the important calls land at odd hours. His scenario watches his calendar for events starting soon, and the filter only passes events whose title contains "Board". The "Board call" alarm is shared with his COO. Both phones ring before the call, and nobody has to set a manual alarm the night before.

**The order worth waking up for.** Sam sells handmade furniture online. Most orders can wait until morning, but a custom order over $2,000 needs a reply the same day before the customer shops elsewhere. The scenario watches new payments, the filter checks the amount is greater than 2000, and only those orders ring Sam and his partner.

**The form from the client who pays the bills.** Maya runs a small video studio for YouTubers. Her intake form feeds a scenario that files every enquiry in a sheet. A second route, with a filter on the email field matching her two biggest channels, goes to the HTTP module, so those enquiries ring her phone while the rest wait in the sheet.

## 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

- **The module returns 429.** The alarm is inside its quiet time, so it already rang recently. If **Return error if HTTP request fails** is on in the module's advanced settings, Make shows this as an error even though nothing is wrong.
- **The module returns 409.** The alarm is switched off. Switch it on in the app.
- **The module returns 404.** The link is wrong, the alarm was deleted, or someone tapped **New URL**. Copy the link again.
- **The module succeeds but nothing rings.** Check **Method** is **POST**; a GET does nothing.
- **The scenario rang late.** A scheduled scenario only runs when its schedule says so, and the alarm rings when the HTTP module runs. Check the scenario's schedule if timing matters.

## Questions

### Do I need an LFG Alarm key or an API token for Make?
No. The link is all it needs. That also means anyone who has it can ring the alarm, so treat it like a password and tap **New URL** on the alarm's page if it leaks.

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

### Can the ring screen show the order amount?
No. LFG Alarm ignores whatever Make 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 Make.
