How to Create a WhatsApp Link with a Pre-Filled Message

A WhatsApp click-to-chat link lets anyone start a conversation with you in one tap, without saving your number first. For a small shop, a tutor, a freelancer or a support team, that one tap removes the biggest hurdle between "interested" and "talking to you". This guide explains how the link works, how to build one correctly (with or without a pre-filled message), where to place it, and the small mistakes that stop it from working.

What a WhatsApp link actually is

WhatsApp supports a simple public URL format called click to chat. When someone opens it on a phone, WhatsApp opens a chat with your number. On a laptop it opens WhatsApp Web or the desktop app.

The basic format is:

https://wa.me/<full phone number>

You can also add a message that appears ready to send in the visitor's typing box:

https://wa.me/<full phone number>?text=<your message>

That is all there is to it. No API key, no business verification and no app install are needed to create the link itself. The person who taps it still needs WhatsApp on their device.

Step 1: Write your number in the right format

Most broken WhatsApp links fail because of the number. The rule is: country code + phone number, digits only.

• Remove the + sign
• Remove spaces, brackets and dashes
• Remove the leading 0 that many people add before mobile numbers

Example for an Indian mobile number:

| How people write it | Correct for a link | |---|---| | +91 98765 43210 | 919876543210 | | 098765-43210 | 919876543210 | | (91) 98765 43210 | 919876543210 |

So the plain link becomes https://wa.me/919876543210. For other countries, use that country's dialling code in the same way (for example 1 for the US and Canada, 44 for the UK, 971 for the UAE).

Make sure the number is actually registered on WhatsApp. If it is not, the visitor sees an error instead of a chat.

Step 2: Add a pre-filled message (optional, but useful)

A pre-filled message saves the customer from wondering what to type, and it tells you where the lead came from. Good examples:

• "Hi, I saw your price list on Instagram. Is the 5 kg pack available?"
• "Hello, I want to book a demo class for Class 10 Maths."
• "Hi, I need help with order number: "

Messages in a URL must be URL-encoded. Spaces become %20, a question mark becomes %3F, and so on. Doing this by hand is error-prone, which is why most people use a generator.

The quickest way is the free WhatsApp Link Generator:

1. Choose your country code and type your number.
2. Type the message you want customers to send.
3. Click generate and copy the link.

The tool builds the encoded link in your browser, so you can paste it straight into your website, bio or email.

Tip: Use a slightly different message for each place you share the link ("Hi, from Google Maps…", "Hi, from your website…"). When chats come in, you instantly know which channel brought them, without any tracking software.

Step 3: Test the link before you share it

Always test on two devices:

1. On your phone: open the link from a notes app or send it to a friend. It should open WhatsApp with the correct number and your message in the typing box.
2. On a computer: open it in a browser. You should see a "Continue to chat" page that opens WhatsApp Web or the desktop app.

If the wrong person opens, check the country code. If nothing opens, check for a stray +, space or leading zero in the number.

Step 4: Put the link where customers already are

A WhatsApp link only helps if people see it at the moment they want to ask something. Places that work well:

• Instagram, Facebook and YouTube bios – "Order on WhatsApp" with your link.
• Google Business Profile – add it as your website or in posts, so local searchers can message you directly.
• Your website – a "Chat on WhatsApp" button on product, pricing and contact pages.
• Email signatures and invoices – customers with a question can reply instantly.
• Online marketplaces and classifieds – where the platform allows links.

For anything printed, such as a shop counter card, visiting card, menu, flyer or delivery bag, turn the link into a QR code. Paste your wa.me link into the QR Code Generator, add your logo and colours, and download it. Customers scan with their camera and land straight in a chat with you. Print the code at a reasonable size, keep strong contrast with the background, and test the printed copy with two or three phones before you print in bulk.

Step 5: Track which link brings real business

The pre-filled message trick above is the simplest tracking method. If you also send people from WhatsApp back to your website (for example, sharing a product page link in replies or broadcasts), tag those website links with UTM parameters using the UTM Link Builder. Your analytics will then show visits that came from WhatsApp as a separate source instead of mixing them into "direct" traffic.

A simple routine for a small business:

1. Create one wa.me link per channel (Instagram, Google, website, printed QR).
2. Give each one a different opening message.
3. At the end of the month, scroll through new chats and count which opening line appears most often.
4. Put more effort into the channels that bring the most conversations.

Common mistakes and how to fix them

• Using the leading 0 or the + sign. The link format needs digits only, starting with the country code.
• Unencoded messages. Characters like &, # and ? can cut your message short. Use a generator rather than typing the URL by hand.
• Very long pre-filled messages. Keep it to one or two short lines. Customers should be able to edit it easily.
• A personal number on a busy business link. If many people will message you, consider a separate number with the WhatsApp Business app, which offers features such as a business profile, labels and quick replies. Check WhatsApp's latest official help pages for current features and terms.
• Forgetting to update old links. If your number changes, every old link and printed QR code stops reaching you. Keep a list of where each link is used.

Example: a home bakery in Pune

A home baker takes cake orders through Instagram and neighbourhood groups. She:

1. Creates https://wa.me/91XXXXXXXXXX?text=Hi%2C%20I%20want%20to%20order%20a%20cake%20(from%20Instagram) with the generator.
2. Adds it to her Instagram bio as "Order on WhatsApp".
3. Makes a second link with "(from flyer)" in the message, turns it into a QR code and prints it on small flyers for the society notice board.
4. After a month, counts which message appears more often and decides whether more flyers are worth printing.

No software subscription, no website builder – just two links and a QR code.

Conclusion

A WhatsApp click-to-chat link is one of the cheapest ways to turn visitors into conversations. Format the number as country code plus digits, add a short pre-filled message that tells you where the customer came from, test it on phone and desktop, and place it everywhere your customers already look.
