Text messages 
 Updated: Nov 3, 2025 
 Text messages are messages containing only a text body and an optional link preview. 
 
 
 
 
 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.
