Send this to your assistant

Create a ClickRuntime automation: when someone registers on my Luma calendar, post their name, the event title and their registration answers to #events in Slack.

Paste it into your assistant. It tells you what it will send or change before it runs live.

Why use it

Why teams use this automation

When you host a dinner for twenty or a workshop with forty seats, each registration matters. A founder might want to greet each guest personally, a sponsor might ask who is coming, and a venue might need an updated headcount. Luma sends confirmation emails to the guest, but the host usually sees only a number going up and must open the event page to learn who registered and what they answered.

When a guest registers, Luma sends a webhook to ClickRuntime, which formats the guest's name and the answers to your registration questions and posts them to Slack. You and your team see each new guest as they sign up, in the channel your event planning already happens in.

It suits small, curated events where every guest counts. It also keeps the whole planning team on the same page.

What you get out of it

Hosts can welcome guests personally
A short message to a guest the moment they register makes an event feel hosted rather than ticketed. That kind of attention increases attendance and goodwill. That small touch is remembered long after the event.
Answers reach the right people
If a guest mentions a dietary need or an accessibility requirement, the team in Slack sees it right away. That prevents last-minute scrambling at the venue. It also saves the host from repeating questions later.
The team shares a live headcount
A running list in Slack lets everyone see how full the event is. Organizers, sponsors and venue contacts can plan with current numbers. That makes every conversation about capacity easier.
Interesting guests are spotted early
A name you recognize, an investor, a customer or an influencer, can be seen straight away. You can reach out, offer a seat at the front or arrange an introduction.
No need to open Luma repeatedly
Without alerts, hosts open the event page again and again to check. A feed in Slack removes that habit and the interruptions it causes. That time is better spent on the guests themselves.

How it works

What happens, step by step

When a guest registers for one of your Luma events, Luma tells ClickRuntime straight away.
ClickRuntime picks out the guest's name, the event and the answers they gave on the registration form.
A message appears in your #events Slack channel with the guest's name and each answer listed underneath.

Build your own

Need it to work differently?

This template is a starting point. Copy the prompt and change it, or describe a different automation from scratch, with your own conditions, more apps or an AI step. Your assistant writes it, tests it and runs it on ClickRuntime.

Your own rules
Conditions, thresholds, filters and exceptions, written the way you'd explain them to a colleague.
Any number of apps
One automation can read from one app and update several others. Over 248 apps are ready, and anything with an API works too.
AI where it helps
Summaries, classification, extraction and drafts use ClickRuntime's built-in AI, with no extra key.
On a schedule or on each event
Runs as often as every 5 minutes, or the moment an app sends an event, and keeps track of what it already handled.

Changes you can ask for

Act only on the items that match your own rules, and skip the rest
Add an AI step, for example to summarize, sort or draft a reply
Add another app, for example also send it to Slack
Combine it with other Luma steps into one automation

Under the hood

The code that runs this automation

This is the Python script that runs each time the automation starts. Your AI assistant writes it for you when you send the prompt, and you allow each step in your assistant. To change how the automation works, describe the change to your assistant and it updates the script for you. For every function it can use, see the script reference.

new_guest_registered_alert.pyexample

from clickruntime import on_event, notify

@on_event
def handle(event):
    body = event.json or {}
    if body.get("type") != "guest.registered":
        return {"skipped": body.get("type")}
    guest = body["data"]
    answers = "\n".join(f"• {a.get('label')}: {a.get('value_text') or a.get('answer')}"
                        for a in guest.get("registration_answers") or [])
    notify.slack(f"New registration for *{guest['event']['name']}*: {guest.get('user_name') or guest.get('user_email')}\n{answers}",
                 channel="#events")
    return {"guest": guest.get("api_id")}

FAQ

Common questions

Which registration answers are included?

All the custom questions you added in Luma are included with the guest's name and email. If a question is very long, the answer is shortened in the post. You can leave out questions that are private or not needed by your team. The post links back to the guest in Luma.

Can I get alerts for only one event?

Yes. Each registration identifies its event, so you can limit the alert to one event or send each event to its own channel. For a series, many hosts use one channel per event and archive it after the event.

Is it fast enough to reply to guests live?

Yes, since the post is triggered by Luma's webhook and not by polling. A guest who registers is usually visible in Slack within seconds. That makes real-time greetings possible if your team is watching the channel during a promotion.

What permissions does it need?

calendar API key. Nothing else in your accounts is used.

Does it need AI?

No. It runs without AI, so it doesn't use your plan's AI allowance.

How many runs does it use?

One run for each event the app sends.

Can I change how it works?

Yes. Describe the change to your AI assistant, for example a different schedule, channel or filter. It updates the automation, tests it and tells you what changed.
