Most small businesses in India already sell on WhatsApp. The hard part is getting customers to start the chat: they have to save your number, find it in their contacts and type a first message. Many simply don't bother.

A click-to-chat link removes all of that. One tap opens a WhatsApp chat with your business, often with a message already typed. This guide shows how to create the link correctly, add a pre-filled message, use it on Instagram, visiting cards and your shop counter, and handle the conversations that follow.

Quick answer

  • Basic link: https://wa.me/91XXXXXXXXXX (country code + number, with no +, spaces, zeros, brackets or dashes).
  • With a ready-made message: https://wa.me/91XXXXXXXXXX?text= followed by your message in URL-encoded form.
  • It is a free, official WhatsApp feature and works on phones and on WhatsApp Web.

1. What is a click-to-chat link?

Click to chat is an official WhatsApp feature. It lets someone start a chat with a phone number without saving it in their contacts. When they tap the link, WhatsApp opens a chat with that number on their phone, or WhatsApp Web on a computer, as long as the number has an active WhatsApp account.

It works for both the regular WhatsApp app and the free WhatsApp Business app. You do not need any other software, sign-up or paid service to create one.

2. Create your link

WhatsApp's format is:

https://wa.me/<number>

Here, <number> is your full phone number in international format: the country code followed by the number, written as digits only. WhatsApp asks you to leave out any zeros, brackets or dashes. For an Indian mobile number, that means 91 followed by the 10-digit number.

Correct: https://wa.me/91XXXXXXXXXX

Wrong:

Test it before you share it. Open the link on a phone that is not yours and on a computer, and make sure it opens a chat with the right business name and number.

3. Add a pre-filled message

You can add a message that appears ready-typed in the customer's chat box. Add ?text= after the number, followed by your message in URL-encoded form:

https://wa.me/91XXXXXXXXXX?text=Hi%2C%20I%20want%20to%20order%20a%20cake

When a customer taps this link, their chat box shows "Hi, I want to order a cake". They can edit it, and nothing is sent until they press send.

Why the message must be URL-encoded

Web links cannot contain spaces and some punctuation, so these characters are replaced with codes. A few common ones:

Character Encoded as
Space%20
New line%0A
Comma ( , )%2C
Question mark ( ? )%3F
Ampersand ( & )%26
Hash ( # )%23

You do not have to do this by hand. Paste only your message, not the whole link, into our free URL Encoder, click Encode, and add the result after ?text=. Emojis and Hindi or other Indian-language text work too: the encoder converts them correctly.

Tips for good pre-filled messages

WhatsApp also supports a link with only a message and no number:

https://wa.me/?text=Check%20out%20this%20offer%20...

Tapping it opens WhatsApp with the message ready, and the person chooses who to send it to. This is useful for a "Share with a friend" button on your website or posts, so customers can forward your offer or product link.

5. Short links and QR codes

6. Where to use your link

If you sell in person, put your WhatsApp QR code next to your UPI payment QR code, but make the two clearly different, so customers do not scan the wrong one.

7. Find out where your customers come from

Plain wa.me links do not come with analytics, so you cannot see how many people clicked them. A simple workaround is to use a slightly different pre-filled message for each place you share the link:

The first message in each chat then tells you which channel brought the customer, as long as they don't delete the text. Over a month, a quick count shows which channels are worth your effort.

8. The official "Chat on WhatsApp" button

For websites, WhatsApp provides an official branded "Chat on WhatsApp" button in three sizes, along with brand guidelines. WhatsApp asks businesses to use the button as it is (without changing its design), to use the latest version, and to make sure it is clearly visible and easy to read. Link the button to your wa.me link. A recognisable official button builds more trust than a home-made one.

9. Get ready to handle the chats

A click-to-chat link only helps if the chats are answered well. The free WhatsApp Business app has tools designed for this:

Sometimes a customer gives you their number in person or over the phone instead. To message them without saving the number to your contacts, use our WhatsApp chat tool: enter the number and it opens a chat directly.

10. Rules and good practice

Frequently asked questions

Is a WhatsApp click-to-chat link free?

Yes. It is a built-in WhatsApp feature, and creating and using wa.me links costs nothing.

Does it work with a WhatsApp Business number?

Yes. The same format works for numbers on the regular WhatsApp app and the WhatsApp Business app.

Why does my link say the phone number is invalid?

Usually the number is in the wrong format, with a +, spaces, dashes, a leading zero or a missing country code, or it is not registered on WhatsApp. Check it against the format above.

Can customers see my phone number?

Yes. A wa.me link contains your number, and once a chat starts, the customer can see the number they are chatting with. Use a separate business number if you want to keep your personal number private.

Is the pre-filled message sent automatically?

No. It only appears in the customer's chat box. They can edit or delete it, and nothing is sent until they press send.

Link formats are taken from WhatsApp's official Help Center article "How to use click to chat" (checked 12 October 2026). WhatsApp Business app menus and features change between versions, so check the app for the current options.
