Text messages | Developer Documentation

Text messages are messages containing only a text body and an optional link preview.

You can have the WhatsApp client attempt to render a preview of the first URL in the body text string, if it contains one. URLs must begin with http:// or https://. If multiple URLs are in the body text string, only the first URL will be rendered.

If omitted, or if unable to retrieve a link preview, a clickable link will be rendered instead.
