WhatsApp chat button for your website: one script tag, no plugin

A floating Chat on WhatsApp button for any website — WordPress, Shopify, Wix or hand-written — from one script tag. Pick the number, the message, the colour and the corner; paste the code before </body>.

In short

Pick the number, the opening message, the label, the colour and the corner; copy the one-line script tag and paste it before the closing body tag of your site. The button floats on every page and opens a WhatsApp chat in one tap. No plugin, no account, no library — the script is under four kilobytes and draws the button itself.

Add this before </body>

Type a number to get the code.

On WordPress, paste the tag into a footer code block or the theme’s footer file; on Shopify, into theme.liquid just above </body>; on Wix or Squarespace, into the site-wide footer code box. The small “Powered by Linkubit” line under the button is one checkbox to remove. What the button starts is an ordinary WhatsApp chat — answering it in a minute is the part that turns a visitor into a customer, and the follow-up guide is about exactly that.

How to add a WhatsApp chat button to your website in 3 steps

  1. Pick the number, the message, the colour and the corner. The number with its country code; a pre-filled first message; the button's colour and whether it sits bottom-right or bottom-left.
  2. Copy the script tag the tool prints. It is one line.
  3. Paste it before the closing </body> tag of your site, or in the place your platform gives for custom code. Reload: the button floats on every page.

Where to paste it, by platform

  • WordPress — Appearance → Theme File Editor → footer.php before </body>, or a "header and footer" plugin's footer box. No WhatsApp plugin needed.
  • Shopify — Online Store → Themes → Edit code → theme.liquid, before </body>.
  • Wix — Settings → Custom code → add to Body end, all pages.
  • Webflow — Project settings → Custom code → Footer code.
  • Squarespace — Settings → Advanced → Code injection → Footer.
  • A hand-written site — before </body> in the layout every page shares.

What the button does, and does not do

It opens a WhatsApp chat with your number and the message filled in, on phones and on desktop (WhatsApp Web). It does not need a plugin, an account, or a cookie; it loads a small script from this site and nothing about the visitor is sent anywhere. What it cannot do is answer: the message arrives on your number, and someone — or something — has to reply. On the WhatsApp Business API that can be a shared inbox or an AI salesperson; the reply inside the 24-hour window is free-form (the window explained).

How do I add a WhatsApp button to my website?

Generate the script tag above with your number and message, and paste it before the closing </body> tag of your site or in your platform's custom-code box. The button floats on every page.

Is the WhatsApp chat button free?

Yes. There is no sign-up and no plugin; the button is one script tag.

Do I need a plugin for a WhatsApp button on WordPress?

No. Paste the script tag into footer.php before </body> or into a header-and-footer plugin's footer box. A dedicated WhatsApp plugin adds nothing this does not.

How do I add a WhatsApp chat button to Shopify?

Online Store → Themes → Edit code → theme.liquid, paste the script before </body>. It shows on every page of the store.

Can I change the button's colour and position?

Yes — the colour and the corner (bottom-left or bottom-right) are options in the tool and are written into the tag.

Does the button work on desktop?

Yes. On a computer it opens WhatsApp Web or the desktop app with the chat ready.

Does the WhatsApp button slow my site down?

No. The script is a few kilobytes, loads after the page, and draws one button.

Does it track my visitors or set cookies?

No. It loads a script from this site and sends nothing about the visitor anywhere; the only thing that happens is the chat opening when the button is pressed.

Can I show the button only on some pages?

Paste the tag only into those pages' templates, or wrap it in your platform's per-page code box. It appears wherever the tag is.

Can several people answer the chats the button starts?

Only if the number is on the WhatsApp Business API with a shared inbox. On the WhatsApp Business app, one phone answers.

What message should I pre-fill?

The enquiry you want: "Hi, I'm interested in…" or "I'd like a quote for…". A pre-filled message that names the product or the page the visitor was on starts the chat on the right subject.

Is a chat button better than a contact form?

For a small business, usually: the customer is already on WhatsApp, the reply arrives where they will see it, and the conversation can continue. A form is better for a long, structured request.
