WhatsApp Click to Chat: Add It to Your Website the Right Way
WhatsApp click to chat is a link or button that opens a WhatsApp conversation with your business number from your website. Add it with a wa.me link and a pre-filled message, place it where visitors need help, and set clear response hours so people know when to expect a reply. This guide shows you how to set it up, where to put it, and how to stay compliant with POPIA.
What Is WhatsApp Click to Chat?
WhatsApp click to chat is a feature that lets anyone start a WhatsApp conversation with a phone number without saving the number first. On your website, it usually appears as a button, an icon, or a floating chat widget. When a visitor taps it, WhatsApp opens with your business number ready to receive a message.
For many South African customers, WhatsApp is the app they already use every day. That makes it a low-friction way to send an inquiry. Instead of filling in a long form and waiting for an email, visitors can send a quick message and get an answer in the same place they chat with friends.
It works especially well for service businesses, shops, clinics, estate agents, and any company that gets repeat questions. It also supports your wider lead generation efforts by giving visitors another easy way to reach you.
How Do You Add a WhatsApp Button to Your Website?
There are three simple ways to add WhatsApp click to chat. All start with a basic link.
Use a wa.me link
The format is:
https://wa.me/27XXXXXXXXX
Replace the Xs with your number in international format, with no plus sign, spaces, dashes, or leading zero. For a South African number such as 082 123 4567, the link becomes https://wa.me/27821234567.
Test the link on your phone and on a desktop browser. On the desktop, it opens WhatsApp Web or the desktop app.
Add a pre-filled message
You can add text that appears in the message box when the chat opens. Add ?text= followed by your message, with spaces replaced by %20:
https://wa.me/27821234567?text=Hi%20there%2C%20I%20would%20like%20to%20ask%20about%20your%20services
A pre-filled message saves visitors typing and helps you understand what they want. Use a different message on each page, such as a product name on a product page.
Plugin or custom code
If you use WordPress, many plugins add a floating WhatsApp button without coding. Choose one that is lightweight and updated regularly, and check it does not load heavy scripts on every page. A simple button with a wa.me link and a small icon is faster than a bulky widget. If speed matters, and it should, ask your developer to add a lean version. Slow widgets can hurt Core Web Vitals, so test your page speed before and after.

Where Should You Place the WhatsApp Button?
Placement affects how often people use it.
Mobile first
Most WhatsApp users arrive on phones. Place the button where a thumb can reach it, such as the bottom right corner. Make sure it does not cover important content, cookie banners, or other buttons.
Contact page
Put the button next to your phone number and email. Many visitors check the contact page when they are ready to reach out. Show your business hours beside it.
Service and product pages
Add a button near key information, such as features, availability, or delivery details. A visitor who has a question about a specific item is most likely to message there. Use a pre-filled message that names the page.
Landing pages
On campaign pages, WhatsApp can sit next to or instead of a form. Test both. Our guide to landing page design that converts explains how to place calls to action. For print and offline campaigns, a QR code can open the same WhatsApp chat.
Set expectations
Tell visitors when you reply. A line such as "We reply on weekdays between 8am and 5pm SAST" prevents frustration. If nobody is online, use an away message in the WhatsApp Business app.
WhatsApp Business App or API: Which Should You Use?
The WhatsApp Business app
The WhatsApp Business app is built for small businesses. It adds a business profile, quick replies, labels, greeting messages, and away messages. It runs on a phone and supports a small number of linked devices. For most small South African businesses, this is the right starting point.
The WhatsApp Business Platform (API)
The Business Platform is for larger volumes. It connects through an approved provider, supports multiple agents, automation, and integration with a CRM or chatbot. It also has stricter rules about templates and opt-in. If you already use or plan to use an AI chatbot, the Platform may fit better.
Which suits you?
If one or two people answer messages and the volume is modest, start with the Business app. Move to the Platform when you need several agents, automation, or system integrations.
POPIA and consent
A WhatsApp conversation involves personal information such as names and phone numbers. Under POPIA, you must handle it lawfully. Add a short line near your button, for example "By messaging us, you agree to our privacy policy," and link to the policy. Do not add people to broadcast lists without consent. Keep records of opt-ins. See our guide to a POPIA compliant website for more.
Also protect your account. Turn on two-step verification in WhatsApp, limit who has access to the phone, and keep your business phone secure.
How Do You Make WhatsApp Click to Chat Work Well?
- Reply quickly. A fast first response is the main benefit of this channel.
- Use quick replies. Save answers to common questions in the Business app.
- Use labels. Mark new enquiries, quotes sent, and completed customers to stay organised.
- Track clicks. Add UTM parameters to the page link or use event tracking in Google Analytics so you know how many people click the button.
- Follow up in other channels. Move complex or sensitive matters to email or a call.
- Review regularly. Check which pages bring the most chats and which messages convert into customers.
Tracking helps you decide where the button belongs. Our data metrics service can set up click tracking. For more ideas on turning visitors into customers, read our post on lead generation strategies for South African businesses.
