Yes, and you do not need an add-on app from anywhere. The WACO chat bubble is one ordinary piece
of HTML, so it installs on any platform that lets you paste code: Shopify,
WordPress, WooCommerce, Wix, Webflow, Squarespace, or a site you built yourself.
Chats from your store land in the same inbox as WhatsApp and Instagram, answered
by the same team, with the same history. There is no separate app to watch.
Get the snippet first
Open Channels in your WACO dashboard.
Under Website live chat, enter your store address and enable it.
Copy the snippet that appears. It is a short <script> block.
One subscription covers any number of websites, and each site gets its own
snippet. A Shopify store, a campaign landing page, and a corporate site can all run at once at no
extra cost.
Shopify
In your Shopify admin, go to Online Store → Themes.
On the live theme, click … then Edit code.
In the left panel, open layout/theme.liquid.
Find the </body> line near the bottom and paste the WACO snippet
immediately before it.
Click Save, then open your store in a new tab. The bubble appears bottom
right.
One honest thing about Shopify: the bubble shows on every storefront page but NOT on checkout. Shopify locks checkout pages against third-party scripts, and that applies to every live chat provider, not just us. If buyers need help while paying, point them to a WhatsApp link on the product page or in the confirmation email.
WordPress and WooCommerce
Two routes, pick whichever suits you:
Without a plugin:Appearance → Theme File Editor, open
footer.php, paste before </body>. This has to be redone when the
theme updates, so use a child theme.
With a plugin (safer): install a code-insert plugin such as WPCode or
Insert Headers and Footers and paste into the Footer section. This
survives theme updates.
Wix
Settings → Custom Code → Add Custom Code.
Paste the snippet, choose All pages, and place it at
Body – end.
Your own site — paste before </body> in the template shared
by every page.
The pattern never changes: find where the platform lets you paste code, and put it before
</body>. If your platform is not listed but has a menu called "custom
code", "footer script", or "code injection", that is the right place.
If the bubble does not appear
Check the site address. The address you entered when enabling the channel has to
match the real store address, including whether it has www.
Clear the cache. Shopify, WordPress, and Cloudflare all hold old pages. Force a
reload, or open the store in a private window.
Make sure it sits before </body>, not after it.
Beyond the chat bubble
If your store needs to send WhatsApp messages automatically, such as order
confirmations, tracking numbers, or abandoned-cart reminders, that is the
WACO API. Your store calls one endpoint and we handle the Meta side.
Anything sent more than 24 hours after the buyer last messaged you has to be a template, see
when you need a template.
