App Verify API - Overview

The Telesign App Verify API allows you to easily integrate frictionless phone number verification on iOS and Android using flash calls. There are two ways you can do verification: Frictionless App Verification and Missed Call Verification.

Frictionless App Verification (Android only)

If you can access call logs programmatically from your app, you can use App Verify API to initiate a call where the number contains a verification code. This can be retrieved on the device and used for verification. Google restricts access to call logs, so to use this option for an Android app you must request and obtain permission from Google to use the call logs. Phone number which calls end user consists of the prefix followed by either five or six digits. The five or six digits after the prefix made up the verification code.

Missed Call Verification

You can use App Verify API to initiate a call with a prefix followed by either five of six digits. The five or six digits after the prefix make up the verification code. The end user receiving the call would manually retrieve the digits from their call logs, and enter them in your app to complete verification.

NOTE:

The verification code length is set up by our Customer Support Team. Please contact them to configure this code. They will help you determine whether the code will be five or six digits.
