What is a WhatsApp chat button?
A WhatsApp chat button is a small widget in the corner of your website. A visitor taps it, and WhatsApp opens on their phone, or WhatsApp Web on a computer, with a chat to your business and a pre-filled message, so all they have to do is tap send.
With Chatfuel, every chat that starts from the button gets an answer in seconds, day and night. The AI Agent replies from your knowledge base, helps customers choose, saves their details as leads, books appointments and hands complex chats to your team in live chat.
