Events live and die on friction. Every extra form field, every "check your email for the link", every unanswered question costs attendees. WhatsApp removes most of that friction: a tap opens a conversation, questions get answered in minutes, and reminders arrive where people actually look. Here's how to use WhatsApp links across the full event lifecycle.
Before the event: promotion and registration
One link per channel
Create a separate click-to-chat link for each place you promote the event, with a pre-filled message that names the event and the source:
https://wa.me/15551234567?text=Hi!%20I%20want%20to%20register%20for%20the%20Growth%20Webinar%20(Instagram)
Create your free WhatsApp link for Instagram, the email invite, the landing page and any partner promotions. When registrations arrive, the first message tells you which channel worked.
Registration by chat
For smaller events — workshops, webinars, community meetups — a chat can replace the registration form entirely:
- Attendee taps the link and sends the pre-filled message.
- Your greeting message asks for name and email (or nothing more, if you don't need it).
- You reply with confirmation and the calendar details.
- Label the contact Registered – [event name].
This works well up to a few hundred registrations with quick replies. Beyond that, keep the form for registration and use WhatsApp for questions and reminders.
Landing page chat button
Put a website chat button on the event page with a pre-filled message like "I have a question about the workshop". People who are unsure about the date, the level, or whether it's recorded will ask instead of leaving.
Selling tickets through WhatsApp
WhatsApp doesn't process card payments for you in most regions, but it's an excellent sales assistant around a ticketing page:
- Answer objections before people abandon the checkout.
- Send the direct ticket link in the chat once the person is ready.
- Handle group bookings and invoices manually, where forms fall down.
- Confirm payment with a personal message rather than a generic receipt.
A simple flow: the ad or post links to WhatsApp → you reply with a short pitch and the ticket link → the buyer pays on your ticketing platform → you send a personal confirmation. The click-to-chat ads guide covers the ad side.
Webinars: reminders that get seen
Email reminders for webinars are often opened too late or not at all. WhatsApp reminders typically get read quickly — but there are rules:
- You need explicit opt-in to send reminders. Ask when they register: "Can we send you a WhatsApp reminder before the session?"
- In the free Business app you reply to people individually or use broadcast lists (recipients must have your number saved).
- For larger audiences, the WhatsApp Business Platform lets you send approved template messages to opted-in contacts — a "Your webinar starts in 1 hour, join here" template is a standard use case. Our Cloud API beginner's guide explains templates.
A practical reminder schedule: confirmation on registration, one reminder the day before, and one an hour before with the join link.
During the event
QR codes on screen and on site
Show a large QR code on the first and last slide, on banners at the entrance and near the registration desk. Generate it with the WhatsApp QR code generator with a message like "Hi, I'm at the conference". Uses:
- Collecting questions for the Q&A without a separate app.
- Sending slides or resources on request.
- Capturing leads at a booth — a scan is faster than a business-card swap.
Live Q&A by chat
Ask attendees to send questions to WhatsApp during the session. A colleague triages them and passes the best ones to the speaker. This works for both in-person and online events and avoids the awkward silence when the host asks "any questions?".
After the event
- Send the recording or slides to everyone who asked, using a quick reply.
- Ask for feedback with a two-line message rather than a survey link.
- Offer the next step — a consultation, a course, the next event — in the same chat where the relationship already exists.
- Ask permission before adding attendees to a longer-term broadcast. The subscriber list guide covers how to do this properly.
Message templates you can adapt
| Moment | Message | |---|---| | Registration confirmation | Thanks, you're registered for Growth Webinar on 14 May, 18:00 CET. We'll send the link here one hour before. | | Day-before reminder | Reminder: Growth Webinar is tomorrow at 18:00 CET. Reply STOP if you'd rather not get reminders. | | Join link | Starting in one hour — join here: [link]. See you soon! | | Post-event | Thanks for joining! Here's the recording: [link]. Any questions? Just reply here. |
Common pitfalls
- Using one generic link everywhere, so you can't tell which promotion worked.
- Forgetting to ask for reminder consent, then wondering why people report the number.
- Having nobody assigned to answer chats during the event itself.
- Printing a QR code too small to scan from a seat.
Handle those four and WhatsApp becomes the easiest part of your event stack: registration questions answered fast, reminders that land, and a warm follow-up channel that's already open.
