Voice OTP
Browse by category
Voice OTP delivers a verification code through a phone call. D7 reads the code aloud using text-to-speech, and the user enters it in your app to complete verification..
Your app calls the Verify API as usual. When Voice is the selected channel, or the next channel in your fallback order, D7 places a call and speaks the code to the user, then validates the code the user enters.
Verification codes are delivered securely via text-to-speech calls. Codes still expire and are validated through the Verify API, like on any other channel..
No. Voice is a channel within the same Verify API, so you don’t need a separate integration for it. You enable it and set its priority in your channel configuration..
