Link wa.me

wa.me is the official WhatsApp domain for generating links that open directly in a conversation. Format: https://wa.me/<DDI+DDD+número>?text=<mensagem>. It's the standard way to get traffic from anywhere to WhatsApp.

Anatomy of the wa.me link

• https://wa.me/ — official domain. Do not use variations like api.whatsapp.com (they exist but wa.me is the recommended standard).
• International number — no spaces, parentheses, dashes or plus signs. Brazil: 55 + DDD + number (Ex: 5511987654321).
• ?text= — query string with pre-filled message, URL-encoded (space = %20, line break = %0A, direct emoji).

Where to use wa.me

• Instagram Bio — CTA "Talk on WhatsApp" takes you to the link.
• Floating button on website — chat widget.
• Meta Ad (Click-to-WhatsApp) — although Meta has native integration, wa.me link serves as fallback.
• QR Code — converts link to scannable image.
• Email Subscription professional.
• Digital business card.

Common errors

• Plus sign in number (+55 instead of 55) — link does not work.
• Parentheses or dashes in local format — link does not work.
• Forgotten DDD — link opens, but with an invalid number.
• Non-URL-encoded text — breaks in browser bar.
• Number that does not have WhatsApp active — opens error.

Wa.me or api.whatsapp.com?

Both work. wa.me is shorter, more memorable, and a priority in marketing. api.whatsapp.com survives due to compatibility. Use wa.me always.
