WhatsApp Business Messaging on Telnyx Numbers

2, Apr 2026

Overview

Telnyx now supports WhatsApp Business messaging for registered Telnyx numbers. Manage the full channel from embedded Meta signup to two-way conversations through the Telnyx Mission Control Portal and REST API.

This adds WhatsApp coverage across 180+ countries to your existing Telnyx messaging stack, without requiring a separate Meta integration.

What's new

  • Embedded signup: Start WhatsApp Business onboarding directly from the Telnyx portal and complete Meta business registration in one flow.
  • WABA management: View and manage WhatsApp Business Accounts (WABAs) and linked number resources in Telnyx.
  • Messaging API: Send WhatsApp messages using the /v2/messages/whatsapp endpoint in the Telnyx Messaging API.
  • Template support: Create and manage message templates for outbound initiation (authentication, utility, marketing, and service categories).
  • Two-way messaging: Reply with free-form messages during the 24-hour customer conversation window.
  • Use your Telnyx number: Register existing Telnyx numbers for WhatsApp if they can receive the one-time verification code.

Why it matters

WhatsApp reaches users across 180+ countries where SMS delivery rates are lower or where customers prefer messaging apps. By managing WhatsApp Business Accounts inside Telnyx, teams avoid building a separate Meta integration: signup, number linking, template management, and message delivery are all handled through the same portal and APIs you already use for SMS and voice.

Example use cases

  • Customer support: Handle two-way WhatsApp conversations from within existing Telnyx-powered workflows.
  • Travel and logistics: Send real-time updates and receive replies from customers globally.
  • Authentication: Use approved WhatsApp templates for OTP and verification flows.
  • Global messaging: Reach users in markets where WhatsApp is the dominant messaging channel.

Getting started

  1. Log in to the Telnyx Mission Control Portal and open the WhatsApp signup flow.
  2. Complete Meta business registration and verify your number with the one-time code.
  3. Link your WhatsApp Business Account and configure phone numbers for WhatsApp messaging.
  4. Create templates for outbound initiation and test delivery through the API or portal.
  5. Monitor conversations and use free-form replies within the 24-hour customer window.
