How to add a WhatsApp button to your website

For most Indian small businesses, WhatsApp is where customers ask, book and order. A button that opens a chat with you, with a message already typed, turns a visitor into a conversation.

The click-to-chat link

WhatsApp's click-to-chat link has the form https://wa.me/<number>?text=<message>. The number is in international format without the plus sign. Anyone who taps it opens a chat with you, with the message ready to send.

Where to put the button

In the first screen of the home page
Next to prices and services, so people ask right away
As a floating button in the corner of every page on phones
On the contact page, next to the call button and map

Questions

Do I need WhatsApp Business for a website button?

No. The click-to-chat link works with regular WhatsApp and WhatsApp Business. WhatsApp Business adds a profile, catalogue and quick replies.

Why does my WhatsApp link not work?

Usually the number is wrong: use 91 and your 10-digit number, without +, spaces or a leading zero.

Can I add a ready message?

Yes, after ?text= in the link. Spaces must be written as %20; AppCub does this for you.

Should the button be on every page?

Yes. Visitors arrive on any page from Google or a shared link, so each page should have a way to reach you.

Can a WhatsApp button take bookings?

It starts a chat; you confirm the booking there. For a booking calendar, make an app.
