What Are WhatsApp Click-to-Chat Links?
WhatsApp's Click-to-Chat feature lets you create a link that opens a chat with you directly, without the user needing to save your phone number first. This is incredibly useful for businesses, customer support, and marketing.
The Link Format
// Basic format
https://wa.me/PHONENUMBER
// With pre-filled message
https://wa.me/PHONENUMBER?text=Hello%20I%20need%20help
// Examples
https://wa.me/5511999999999 // Brazil number
https://wa.me/5511999999999?text=Hi%20there // With messageImportant Rules
- Use the full international format without + signs, dashes, or spaces
- Include the country code (55 for Brazil, 1 for US, 44 for UK)
- The pre-filled message must be URL-encoded (spaces become %20)
- Links work on both mobile and desktop (WhatsApp Web)
