Add a WhatsApp button

1. In the editor, add the WhatsApp block.
2. Enter your number with the country code, like +51 987 654 321. Spaces, dashes and the plus sign are fine.
3. Optionally write the message the chat opens with, for example “Hi! I'd like to order…”. Visitors can still change it.
4. Publish your changes.

The button opens the WhatsApp app on phones and WhatsApp Web on computers. Your number is visible to anyone who opens the chat, as with any WhatsApp link.
