What you can do with Voice API

A Voice API lets your software place and manage phone calls programmatically: reading out a code, playing a recorded message or connecting two people.

Automated voice messages

Play recorded or spoken messages to customers.

Voice verification

Deliver codes by voice as an alternative to text.
