Release notes

WhatsApp is now a Verify channel on Telnyx

11, Jun 2026

Telnyx Verify now supports WhatsApp, so you can deliver one-time passcodes (OTPs) to users over WhatsApp using approved authentication templates. This gives businesses another verification channel alongside SMS and voice, helping them reach users on the messaging platform they use most.

Why it matters

SMS OTPs are the default for verification, but they aren’t always the right channel. Delivery rates vary by country, prices fluctuate, and some markets have moved their primary messaging to WhatsApp. Adding WhatsApp to Verify gives you a higher-deliverability option in those markets and a fallback path when SMS underperforms. Running it through Telnyx Verify means you don’t have to build the orchestration, retry logic, or template management yourself.

How it works

Telnyx Verify abstracts the OTP delivery flow. You send a verification request specifying the user’s phone number and the channel, Telnyx generates and delivers the code, and your application checks the user-submitted code against the Verify API.

For WhatsApp OTP delivery, Verify uses the WhatsApp Business API to send an authentication template message containing the verification code.

Pricing

Use Verify API via WhatsApp Messaging for $0.03 per successful verification plus WhatsApp API pricing.

Getting started

  1. In Mission Control, navigate to Identity → Verify.

  7. Validate the user-submitted code using the Verify API to complete the verification flow.
