Notes
  • Requires IP whitelist.
  • Outside the 24h window use POST /inbox/send-template-message.
  • Session media on Cloud External API: multipart file fields only. Session *_url fields are not implemented on this surface.
  • For native PDF/image bubbles outside the session window use templates with header_media_url.
  • CTA / lists / product require Cloud + open session.
  • Prefer whatsapp_account_id or exact from_number (mismatched from_number returns sender_not_found).
API v1 equivalent Prefer POST /v1/messages for new integrations. Open API v1 docs →
