Message Links

Message links (click-to-chat links) open WhatsApp with a prefilled conversation to a business phone number. They are commonly used on websites, ads, QR codes, and email.

Typical format

Links usually follow Meta’s wa.me / WhatsApp click-to-chat patterns with the full international phone number (no + in some formats) and an optional prefilled text parameter.

Partner tips

• Use the registered WhatsApp Business number, not a personal number
• Keep prefilled text compliant and useful
• Combine with Ads that Click to WhatsApp style entry points where relevant
