How to Add WhatsApp Button to Wix Sites Easily 2026

From your site's dashboard, open the apps section where Wix surfaces "professional solutions to power your Wix website," complete with a search bar for finding specific tools. This is where WhatsApp chat widgets live alongside other communication apps — searching directly is faster than browsing categories if you already know you want a WhatsApp-branded chat experience rather than a generic contact form.

Once installed, open the widget's General settings and look at Widget Behavior. You get three real options here: Simple Link, which sends visitors straight into a WhatsApp chat with no popup shown at all; Single Chat, which lets users chat with one specific agent; and Multi Chat, which allows visitors to choose between multiple agents. Multi Chat is the richer option and shows a live preview of the floating chat bubble as you configure it, complete with a sample greeting and an agent card.

Move to Content settings, under the Chat tab. Here you set the Header title and Header subtitle that appear at the top of the chat window when a visitor opens it — something like "Hey, Welcome" paired with a subtitle explaining who will respond and how, including a fallback email address for visitors who'd rather not chat. There's a separate Footer text field beneath it, and each field shows a live character count so you know how much room you have before it gets cut off.

Replace the generic placeholder text with your own — swap "Hey, Welcome" for something naming your business, like "Hey, Welcome to [Your Site]" so the first thing a visitor sees confirms they're in the right place. Tabs for Badge and Welcome sit next to Chat within the same Content settings panel, letting you customize the small badge that appears before the chat opens and a separate welcome message shown on first contact.

Under Agents, add the person or people who'll actually be answering — this is what powers the agent card shown in the preview, with a name, role, and photo rather than an anonymous chat box. Back in General settings, User Attention controls include a Show new message indicator toggle and an Indicator behavior setting choosing between Smart and Always, which governs how aggressively the widget nudges visitors to notice it.

The Position and Visibility tabs in the left rail control where the widget sits on the page and whether it shows on every page or only specific ones. Toggle between desktop and mobile preview using the device icons at the top of the editor, since a floating chat widget is exactly the kind of element that can crowd other fixed elements — like a cookie banner or back-to-top button — on a small screen.

Before publishing, the editor's status still shows Unpublished at the top — use Preview to interact with the widget as a visitor would, opening the chat and confirming your header and footer text render the way you configured them. Once it's live, send an actual test message through it so you know replies land wherever your agents are actually watching, whether that's WhatsApp directly or a connected inbox.
