Verify
Validate users with SMS, Voice, Email, Push, and Time-based One-time Passwords.
User verification built for global reach and massive scale
Enable user validation with your choice of TOTP, Push, SMS, voice, or email through one API.
Verify users on any channel
Authenticate users on the channels they prefer. Enable user validation with your choice of Push, SMS, voice, or email through one API.
Global carrier‑approved messages
Use carrier‑approved templated messages to eliminate carrier message filtering. Easily send messages globally using Twilio’s automatic translation and global regulations compliance.
Flexible Push Authentication
Add push authentication into your applications for a low‑friction way to silently approve users via a secure channel, without the hassles or costs of One‑Time Passcodes (OTPs).
The benefits of using Verify
Verify solves complex development challenges so you can focus on the code that counts.
Phone number management solved programmatically
The Verify API determines the quantity, type, and locale of phone numbers you’ll need to verify users, saving you from spending cycles purchasing and managing phone numbers.
Integrate Verify easily
The Verify API integrates into your sign up flow, so you can seamlessly capture and confirm user phone numbers as part of their onboarding process.
Scale globally without the hassle
Verify simplifies authentication processes like orchestrating multiple APIs, or managing country‑specific number pools. Now global, scalable verification is an API call away.
How the Verify API works
Verify uses two API endpoints to seamlessly check that a user is the owner of the phone number they provide.
The start API endpoint
When the user is validating their phone number, Verify sends the user a 4‑10 digit verification code via SMS, Voice, or Email and waits for their response.
The check API endpoint
Verify checks the user’s input matches the code. If they match, Verify registers the phone number as approved.
Integration was extremely fast, it was a nice surprise. We aren't used to being able to integrate with a third‑party so easily.
