Verify API - Overview

πŸ“˜

NOTE:

To add this product to your account, contact a Telesign expert. This product is available for full-service accounts only.

The Telesign Verify API makes it easy for you to set up phone-based, multi-factor authentication (MFA) using multiple channels and methods.

Use this product to:

  • Authenticate end users via one-time passcode (OTP) on their preferred messaging channel:
    SMS, WhatsApp, Viber, RCS, email
  • Authenticate end users on their mobile devices seamlessly in the background without the need for any user action.
  • Authenticate end users via push notification to their mobile device.

When your preferred verification method is not available for a recipient, you can have the system automatically fail over to a backup method, such as SMS OTP.

OTP verification is currently available to all Full-service customers using our REST API. Other verification methods depend on the Telesign Verify Android SDK. Contact our sales team for availability of the Android SDK in your region.

Common use cases

  • Reduce friction that authentication causes for your end users, while still conducting MFA.
  • Reduce time spent by your mobile dev team creating a complex authentication solution from scratch.
  • Quickly and easily adjust your mix of verification methods over time with the same integration and the same API.
