WhatsApp: Start Chat Button

Adding WhatsApp: Start Chat Button to a Wix site is meant to be a no-code setup. The app is installed from the Wix App Market, then configured with the WhatsApp number, display style, greeting message, and optional representative details.

Before you start

  • Choose the WhatsApp number that should receive website inquiries.
  • Decide whether the chat should go to one person or multiple representatives.
  • Write a short default message that helps visitors start the conversation.
  • Decide where the button should appear: all pages, key conversion pages, or only specific sections.

Basic setup steps

  1. Open the Wix App Market and search for WhatsApp: Start Chat Button.
  2. Add the app to the site you want to improve.
  3. Open the app settings from the Wix editor or dashboard.
  4. Enter the WhatsApp phone number in international format.
  5. Customize the button style, position, label, and popup behavior.
  6. Add a pre-filled message, such as: Hi, I have a question about this service.
  7. Preview the site on desktop and mobile before publishing changes.

Recommended first configuration

For a simple business website, start with one visible floating button, one representative, and one neutral message. A good first message is specific enough to help your team reply, but not so long that the visitor feels boxed in.

Example: Hi, I found your website and have a question about your services.

For a store, you can make the message more commercial: Hi, I have a question before placing an order.

Placement tips

The button should be visible without blocking important page actions. On mobile, test it near sticky carts, cookie banners, accessibility widgets, and bottom navigation. If too many floating elements compete for the same corner, the WhatsApp button can feel intrusive instead of helpful.

Start by placing the button on high-intent pages: service pages, product pages, pricing pages, booking pages, contact pages, and quote request pages. If performance looks strong, expand it sitewide.

Testing checklist

  • Click the button on desktop and confirm WhatsApp Web opens correctly.
  • Click the button on a phone and confirm the WhatsApp app opens correctly.
  • Confirm the pre-filled message appears in the chat box.
  • Check that each representative profile routes to the correct number.
  • Review the button against light and dark site backgrounds.
  • Confirm the widget does not cover checkout, booking, or form buttons.

Once the basics work, refine the copy and placement based on real customer behavior. A WhatsApp button performs best when it feels like a natural support path, not a pop-up fighting for attention.
