WhatsApp button

The WhatsApp button for your website

Q: Do I need WhatsApp Business?

No. The button opens a normal wa.me chat to your number — the chat is visitor-initiated. You don't need the WhatsApp Business API or any approval, and there's no consent headache because the visitor starts the conversation.

Q: Can I add a WhatsApp button without a plugin?

Yes. You paste one line before . No WordPress plugin required; it works on any platform, and you remove it by deleting that one line.

Q: Does the button slow my site down?

No. The widget is ~19 KB (brotli), loads async in a Shadow DOM and has zero impact on your Core Web Vitals.

TL;DRA WhatsApp button is a floating button on your website that takes the visitor into a WhatsApp chat. With LeadButton it's not a bare link: a guided flow asks a short question first, qualifies the visitor, then opens WhatsApp with a pre-filled message — or hands off to a form or call.

What you get

Everything in one step of the flow

Deep-link to WhatsApp with a pre-filled message

The WhatsApp step opens the chat with a ready-made message, so the visitor only has to press send.

Qualify before the hand-off

Branching questions guide the visitor, with featured replies highlighted. Only then does it go to WhatsApp.

Toast bubble and attention badge

A teaser ("👋 Got a question?") with timing and a delayed badge draws attention — dismiss-aware.

~19 KB, in a Shadow DOM

The widget loads async and renders in a Shadow DOM, so it can never break your site's CSS — and yours can't break it.

13.8M

WhatsApp is the Netherlands' largest platform — 13.8M users, 12.1M daily, bigger than YouTube, Instagram or Facebook.
