The App Verify API allows you to easily embed frictionless phone number verification on iOS and Android using SMS and voice capabilities.
Before going further, if you know you want to do verification using SMS for iOS devices, take a look at TeleSign's iOS Mobile App Verification Sample App. Using deep links, and TeleSign's SMS API, you can set up verification for iOS devices.
TeleSign's App Verify API uses voice to offer easy, in-app verification without revealing your credentials. There are two ways you can do verification:
- Missed Call Verification - You can use the App Verify API to send a call with a prefix followed by five digits. The five digits make up the verification code. The end user receiving the call would manually retrieve the five digits, and enter them in your app to complete verification.
- Frictionless App Verification - If you can access call logs, you can use the App Verify API to send a call where the number contains a verification code. This can be retrieved automatically on the handset and used for verification. Google restricted access to call logs, so this option is not possible in most cases, unless you request and obtain permission from Google to use the call logs.
