WhatsApp click-to-chat links and QR codes: a practical guide for small businesses

By the BotSetu team · Published 29 October 2026 · WhatsApp · Small business

Most customers would rather send a WhatsApp message than save your number, open the app and search for you. A click-to-chat link removes those steps: one tap or one scan, and the chat opens with a message already typed. This guide shows how to make the link, where it brings the most messages, and what to check before you print it.

What a click-to-chat link is

WhatsApp's click to chat feature lets anyone start a chat with you without saving your number. The link format is https://wa.me/ followed by your full number with the country code, without "+", spaces, dashes or a leading zero. For an Indian number 98765 43210 that is https://wa.me/919876543210.

You can add a pre-filled message with ?text= and the message encoded for a URL, for example https://wa.me/919876543210?text=Hi%2C%20I%20want%20to%20book%20a%20table. The customer still has to tap send, so they stay in control.

How to make one in under a minute

1. Open our free WhatsApp link and QR generator.
2. Enter your WhatsApp number with the country code.
3. Type the message customers should send. Make it specific: "Hi, I want to book a haircut" works better than "Hi".
4. Copy the link, or download the QR code as a PNG.
5. Test it on your own phone and on a friend's phone before you share it.

Where the link brings the most messages

• Google Business Profile: add it as your website or booking link where allowed, and mention WhatsApp in your description.
• Instagram bio and Facebook page: one link that opens a chat is easier than "DM for price".
• Your website: a WhatsApp button on every page, especially pricing and contact.
• Printed QR codes: counter standees, bills, visiting cards, menus, flyers and delivery bags.
• Different messages for different places: use "Hi, I saw your flyer" on flyers and "Hi, I saw your Instagram" on Instagram, so you know which channel works.

Printing a QR code that scans every time

• Print it at least 2.5 cm wide; bigger for standees read from a distance.
• Keep dark modules on a white background with a clear white border around the code.
• Do not stretch it, put it on a glossy curved surface, or cover it with a logo.
• Add a line of text above it: "Scan to WhatsApp us" so people know what it does.
• Scan the printed proof with two different phones before you print hundreds.

Common mistakes

• Leaving out the country code, or adding a 0 or + in the link.
• Using a personal number that is often switched off or full of family chats.
• Sharing a link and then not replying for hours. A fast first reply matters more than the link itself.

When messages start piling up

A good link brings more chats, and the same questions repeat: prices, timings, location and booking. The free quick replies in the WhatsApp Business app help at first. When you need replies at night or in several languages, a WhatsApp bot on the official API can answer and book for you. That is what a BotSetu WhatsApp bot does, in 15+ languages.
