WhatsApp Link and QR Code: How to Create a wa.me Click-to-Chat Link for Your Business
A customer sees your shop's Instagram bio, your Google listing or a poster outside your salon. They want to ask one question. If the next step is "save our number, open WhatsApp, search for the contact, type a message", most of them will not bother. If the next step is one tap or one scan, a good share of them will message you right then.
That one tap is a **WhatsApp click-to-chat link**, usually called a wa.me link. It costs nothing, takes two minutes to create and works with both the WhatsApp Business app and the WhatsApp Business API. This guide shows the exact format, how to add a pre-filled message, where to place your links and QR codes, and how to find out which placement actually brings enquiries.
What a wa.me Link Is
A wa.me link is a normal web address that opens a chat with a specific WhatsApp number. On a phone with WhatsApp installed, it opens the app with your chat ready. On a laptop, it opens WhatsApp Web or the desktop app. If WhatsApp is not installed, the person is sent to a page that helps them get it.
The basic format is:
**https://wa.me/919876543210**
Here 91 is the India country code, followed by the ten-digit mobile number. There is no plus sign, no spaces, no dashes and no leading zero. Getting this wrong is the most common reason a link opens an error page.
Adding a Pre-Filled Message
You can add the first message so the customer only has to press send. Add **?text=** after the number, followed by your message with spaces written as %20:
**https://wa.me/919876543210?text=Hi%2C%20I%20want%20to%20know%20about%20your%20offers**
A pre-filled message helps in two ways. First, it removes the blank-screen hesitation that stops people from writing. Second, it tells you where the person came from, because you can use a different message for each placement. A message like "Hi, I saw your Instagram bio" tells your team, and your auto-reply, exactly how this lead arrived.
Writing the encoded text by hand is easy to get wrong. Our free WhatsApp link generator builds the link for you: enter your number and message, and copy the result.
Turning the Link into a QR Code
A QR code is just the same link in a scannable form. It is the right choice anywhere a customer cannot tap: printed material, shop counters, packaging, hoardings and shop windows. Use our WhatsApp QR code generator to create one, then test it with two or three different phones before you print anything.
Three practical tips for printed QR codes:
Keep it large enough. A code smaller than about 2 cm across is hard to scan from a normal distance. Bigger is safer on posters and shop fronts.
Add a short instruction. Write "Scan to chat on WhatsApp" next to it. Many people still do not know what to do with a bare code.
Leave a quiet border. Do not let text or design touch the edges of the code. A clear margin around it makes scanning reliable.
Where to Place Your Links and QR Codes
Put the link wherever a customer is already thinking about you:
Instagram and Facebook bio. Instagram lets you add a link to your profile, and your bio is the first place people look for a way to contact you. Use a message such as "Hi, I found you on Instagram".
Your website. Add a WhatsApp button on product pages, the contact page and the footer. Our chat button generator creates a floating button you can paste into your site.
Google Business Profile. Add your WhatsApp link where a website or booking link is accepted, so people searching for you on Google can message directly.
Shop counter and window. A QR code at the billing counter catches customers who forget to ask something, and a code in the window catches people walking past after closing time.
Bills, packaging and delivery slips. A printed code on the invoice lets a customer reach you for exchanges, service or reorders without searching for your number.
Email signatures and SMS. Every email and text you already send can carry a one-tap way to reach your team.
Ads. Meta's click-to-WhatsApp ads send people straight into a chat, and the same thinking applies. See our guide to click-to-WhatsApp ads for how that works.
Use a Different Message for Each Placement
If every link says "Hi", you will never know what works. Give each placement its own opening line:
Instagram bio: "Hi, I found you on Instagram. Can you share your catalogue?"
Shop counter QR: "Hi, I bought from your store today. I need help with my order."
Website product page: "Hi, I am interested in the product on your website."
Invoice QR: "Hi, I need service support for my recent purchase."
Your team now knows the context before they read anything else, and an auto-reply can answer accordingly. With VedLink AI you can set auto-reply triggers that fire on specific opening phrases, so the Instagram visitor gets your catalogue and the invoice-QR customer gets a service form, without anyone typing.
What Happens After the Customer Taps
The link only opens the chat. What you do in the next minute decides whether it becomes a sale. Three things matter:
Reply fast. A customer who messages you is asking for attention right now. A first response within a few minutes feels helpful, and one after several hours feels like you do not care. An instant automated greeting keeps them engaged until a person is free.
Ask one clear question. Instead of "How can I help you?", ask "Which product are you looking at?" or "Which day suits you for the appointment?". Buttons make it even easier.
Save the contact and its source. Every person who messages you is a lead. Store their name and where they came from so you can follow up later. Our guide to segmenting your WhatsApp contacts shows how to use that source information for better campaigns.
Tracking Which Link Works
You do not need complicated analytics. If each link uses its own opening message, count the chats that arrive with each one for a month. If the counter QR brings 40 chats and the website button brings 4, you know where to put more effort. Treat any such numbers as your own data, not an industry benchmark: every business is different.
For paid campaigns, keep a separate link for every ad or campaign, so you can compare the cost of enquiries fairly.
Common Mistakes to Avoid
Using a personal number. Link to your business number. If your team changes, the number should stay with the business.
Forgetting the country code. A link without 91 will not connect to an Indian number.
Leaving the number without a reply system. A link that sends people to a chat nobody watches damages trust. Set business hours, an away message and a proper team inbox so that chats are assigned and answered.
Printing before testing. Scan every QR code with an Android phone and an iPhone before sending it to the printer.
Frequently Asked Questions
Is a wa.me link free? Yes. Creating and using the link is free. Normal WhatsApp rules and any applicable conversation charges depend on how you run your account, so check our pricing explainer for the API side.
Does the customer need to save my number first? No. The link opens a chat even if your number is not saved in their phone.
Can one link work for the WhatsApp Business app and the API? Yes. The link only points to a phone number. It works with whichever account owns that number.
Can I have different links for different team members? You can use one number and route chats to different team members inside your inbox, which is usually easier than managing many numbers.
The Bottom Line
A click-to-chat link is the cheapest lead-generation tool you have. Create one per placement, add a pre-filled message that says where the customer came from, print QR codes wherever people wait or walk past, and make sure a fast reply is waiting when they message.
