Voice added as a channel to Verify API
May 12th, 2025 by [email protected]
Who is affected: Full-service customers
Products affected: Verify API
Changes
- New channel added to Verify API: Voice joins Silent Verify, Push Verify, SMS, WhatsApp, RCS, and email as a channel for Verify API, which allows you to set up phone-based, multi-factor authentication (MFA) using multiple channels and methods.
- Voice expands your verification options: The addition of voice as a Verify API channel provides a phone call as an additional method for authenticating end users via a one-time passcode (OTP).
- Send OTP codes in the language suitable for your end users: Using Text to Speech (TTS), you can select a supported language to specify the language that the service will use when delivering a OTP to your end user. If a language selection isn't provided, the default language, English (US), is used to deliver the OTP.
- Voice expands your channel fallback options: In addition to Silent Verify, Push Verify, SMS, WhatsApp, RCS, and email, voice increases your automated fallback options from one channel to another. For example, if SMS fails or times out because your end user's mobile device isn't working, the OTP can still be sent automatically using a voice call if voice is enabled as a Verify API fallback option.
