Overview

Method for sending messages with action buttons. There are three button types:
  • CALL — Button to call a phone number
  • URL — Button to open a link
  • REPLY — Quick reply button
Do not combine all three button types in the same message. Send CALL + URL buttons together, and REPLY buttons separately. Combining all of them causes errors on WhatsApp Web.
For copy-code buttons, use the URL format: https://www.whatsapp.com/otp/code/?otp_type=COPY_CODE&code=YOUR_CODE
The response structure is identical to Z-API. Your existing code that processes these returns will continue working without changes.
