Verify Silent Network Auth Technical Overview

This feature is in Pilot, talk to an expert to request access to this feature.

The API for Verify Silent Network Auth (SNA) is the same Verify API used for sending SMS one-time passwords (OTPs), involving REST calls to the Verifications and Verifications Check resources (sample code provided).

As the sequence diagram shows below, a common scenario of phone number verification in a mobile app involves interactions between the end-user, customer developer, customer mobile frontend, customer backend, the Verify API for SNA, and the underlying carrier (MNO) that is ultimately checking if the end-user provided phone number matches the phone number to the SIM on the mobile frontend's device.
