With more than 2 billion people using WhatsApp around the world to send 60 billion messages every day, the chat app has revolutionized the way we communicate. With an enterprise-grade API, companies can now send notifications and provide customer service through WhatsApp in a secure, reliable, and customer-friendly way.


Learn the specifics of how to send a text-only message on WhatsApp.

Send a text message to customers in any of the following formats:

  • Bold (*using asterisks*)
  • Italic (_using underscores_)
  • Strikethrough (~using tildes~)
  • Code (“`using three backticks“`)

Messages can contain up to 1024 characters for message templates and 4096 characters in session messages. Text limitations vary on the relevant sections in templates. 

Note that URL characters count in message length limits. Make sure to keep text messages and URLs within the character limit. You also have the option to display URL previews in messages.

ℹ️ Emojis are supported for both templated and session messages.
