What is WhatsApp: Start Chat Button?

WhatsApp: Start Chat Button is a Wix App Market app by Certified Code that adds a direct WhatsApp contact entry point to a Wix website. Instead of asking visitors to copy a phone number, save a contact, or search for a support channel, the app gives them a button or popup that opens a WhatsApp conversation from mobile or desktop.

For many service businesses, local shops, consultants, restaurants, real estate teams, and ecommerce stores, WhatsApp is already where sales and support conversations happen. The value of the app is reducing the gap between browsing and asking a question. A visitor can move from product page, service page, booking page, or pricing page into a chat thread with less friction.

Core features

• A one-click WhatsApp button designed for Wix sites.
• Pre-filled messages so visitors can start with useful context instead of an empty chat.
• Customizable visual styles for matching the widget to the site's brand.
• Mobile and desktop support, opening WhatsApp in the most practical method for the visitor's device.
• Multiple representative profiles, useful when a business wants separate contacts for sales, support, bookings, or regional teams.

Who should use it

The app is especially useful when a purchase or booking often depends on a quick human response. Examples include service quotes, appointment questions, order follow-ups, product availability checks, event inquiries, and high-intent sales conversations.

It is less useful for websites that already route every conversation through a help desk, live chat team, or CRM workflow. In those cases, WhatsApp can still be valuable, but the team should decide whether direct messaging fits their response process.

Why it matters for conversions

A contact form is asynchronous and often feels formal. A live chat tool may require a new inbox. WhatsApp is different because many visitors already have it installed and understand the interface. That familiarity can make the first message feel easier, especially on mobile.

The app also helps preserve intent. If a visitor is already evaluating a service, a WhatsApp button lets them ask the question while they are still on the page, instead of leaving the site to find contact details elsewhere.

Best use cases

• Sales inquiries from landing pages.
• Booking or appointment questions.
• Support handoff for existing customers.
• Product questions before checkout.
• Local service quote requests.

For best results, the button should not be treated as decoration. It should be connected to a real response workflow, with a clear greeting, the right representative, and a pre-filled message that tells the business which page or offer the visitor came from.
