# How to add a Set an LFG alarm button to your event

Parties and events · https://lfg.gm/set-an-lfg-alarm-button · Updated 2026-11-10

Most event pages have an **Add to calendar** button. Guests tap it, the event lands in a calendar that's already full, and on the night a small reminder slides past with everything else. A **Set an LFG alarm** button sits right next to it and does something louder: the guest picks how early they want to be rung, and their phone rings like an alarm clock before your event. LFG Alarm is a social alarm clock for iPhone, Android and lfg.gm in a browser. You don't need an account or the app to add the button. It's a link.

## Why a guest would tap it

A calendar entry is a note to self. An alarm is a promise to be somewhere. People who set one mean to come, and it rings at a moment they chose: two hours before, so they leave in time, or right at the start for an online event.

It's also the guest's own alarm. They choose when it rings and how loud, and nothing is set until they tap **Create alarm**.

## Make your link

Start with your event's page: Luma, Partiful, Eventbrite, Ticketmaster, Posh and more, or any page of your own that shows the event. Put it after `lfg.gm/add?url=`, like this:

`https://lfg.gm/add?url=https://example.com/events/rooftop-party`

That's the whole link. When a guest opens it, Rocco, the cat who does the watching in LFG Alarm, reads the event's name, time, place and picture from your page.

If your event's own link has an `&` in it, swap each `&` for `%26`, or ask your AI app to make the link for you.

No event page? You can write the details into the link instead: a name, the exact start time with its time zone, and a place. The [developers page](https://lfg.gm/developers#add-button) shows how.

## Where to put it

- **Your event description.** Most event sites let you add links to the description. Put it near the top: "Want a real alarm before doors? Set an LFG alarm."
- **Your confirmation and reminder emails,** right under the date, where people look for the time.
- **Your own site or link page,** beside the ticket link.
- **The group chat or your socials,** when you announce the event.

On a site or in an email, use the badge, so it looks like the other buttons. It comes in black, white, violet and volt. The HTML to copy, for a page and for email, is on [the developers page](https://lfg.gm/developers#add-button).

## What your guest sees

- **With the app:** LFG Alarm opens on your event, already filled in. They pick when it rings (at the start, or 30 minutes, 1 hour or 2 hours before) and tap **Create alarm**.
- **Without the app on a phone:** lfg.gm shows your event and where to get the app. The link waits through the install, so your event is there the first time they open it.
- **On a computer:** lfg.gm shows your event with a code to scan, so they can set it on their phone.

## The button, or one shared alarm

There are two ways to use LFG Alarm for an event, and they suit different hosts:

| | The Set an LFG alarm button | One shared alarm |
|---|---|---|
| You need | Just the link | The app and an account |
| Who picks the time | Each guest | You, for everyone |
| You can see | How many set an alarm, on your event's lfg.gm/add page | How many joined |
| Your note on it | No | Yes, your Keeper's note |
| Best for | Big events, ticket sites, newsletters | A crew, a party, a group you know |

For one alarm you share with everyone, see [how to get people to actually show up to events](https://lfg.gm/how-to-get-people-to-show-up-to-events).

## Ask your AI to make the link

If you use an AI app such as Claude or ChatGPT, it can build the link and the button for you. It doesn't need the LFG Alarm connector for this.

**Try this.** Paste it into ChatGPT, Claude, Grok or another AI agent that has the LFG Alarm connector (https://mcp.lfg.gm), not into the LFG Alarm app. The person needs the LFG Alarm app on their phone.

> Make me a Set an LFG alarm link for my event page, [your event link], using lfg.gm/add. Then give me the HTML for the black badge to put next to my Add to calendar button.

Why it works: It gives the event page and asks for the two things you'll paste: the link and the button. The rules for the link are in lfg.gm/llms.txt, which most AI apps can read.

## Questions

### Does it cost anything?
No. There's no key and no account for you. Each guest's alarm is on their own LFG Alarm account.

### Can a link set an alarm by itself?
No. Anyone can make a link, so the guest always taps **Create alarm** themselves.

### What if my event moves?
Change the time on your event page. LFG Alarm reads your page again every day, and 24 hours and 3 hours before it starts, and every guest's alarm moves with it, keeping the lead they picked. Guests are told. If you cancel it on your page, their alarms turn off and they're told that too.

### Does it work for online events?
Yes. Use the event's page, and guests can pick **At start** so the alarm rings as it begins.
