Send Authentication Template

POSThttps://public.leadpattern.com/whatsapp/message/auth-template
WhatsApp Connectedapplication/json60 req/min

Send an approved AUTHENTICATION/OTP template. Dedicated endpoint — Meta requires a positional body parameter (the code) plus a matching OTP button parameter, which the generic /whatsapp/message/template endpoint does not build. Supports batch sending via the messages array.

  • Only for AUTHENTICATION-category templates.
  • content.templateData is ignored — the OTP value comes from content.code.
