Is there an official Chat on WhatsApp button for my website?

Yes. WhatsApp provides a Chat on WhatsApp button, currently only in English, that opens a chat through a wa.me link.

• The link is wa.me/ followed by your full number in international format, with no zeroes, brackets or dashes.
• Add ?text= to the link to fill in a message for the customer.
• A chat button starts a conversation. It does not take a payment or an address by itself.
• Test the link on your own phone before you publish it.
