Verify V2 API Now Available in Early Access
Customers all over the globe are using phone numbers to quickly establish identity and provide security to their applications and platforms. Now Vonage has made it even easier — and you can now access this powerful tool!

Simplifying Two-Factor Authentication
At Vonage, we help hundreds of businesses send millions of 2FA requests in all major regions, including North and South America, Europe, and Asia.
Our customers tell us they’re aware of the multitude of authentication options available — from less expensive options like email to more expensive (and more complex) soft tokens, SDKs, and even hard tokens like physical key fobs.
But there’s one simple, easy-to-use API that removes the complexity of 2FA at a global scale. Our Verify V2 API can be tested in a matter of minutes and scaled globally in a matter of hours.
Today, we’re excited to announce Verify V2 is available to the public in the Early Access product phase. We’ve been working hard to enhance Verify V2, making it an even more powerful two-factor authentication tool for developers and businesses. To get started, simply refer to the developer documentation.
New Channels for Authentication
With 1.5 billion people registered and 500 million daily active users, WhatsApp is a popular channel all over the world, connecting people over a basic internet connection and serving as a great primary or secondary channel to SMS. WhatsApp has also proven itself to be an awesome way to authenticate end-users, which is why we’re excited to offer WhatsApp as a channel for Verify V2!
The WhatsApp channel will integrate seamlessly into our channel lineup for delivering one-time passwords. Verify will take care of all the complexity related to signing up for a WhatsApp Business Account, with auto failover to SMS and Voice if and when needed.
Email is now available as an additional verification channel to supplement SMS, voice and WhatsApp. Whenever a user is unable to verify using their phone, a one-time passcode can be sent to their email address in order to authenticate, providing even more flexibility.
Improved Product Flexibility
Developers can now control how one-time passcodes are delivered using the "type" and "number" strings within the "to" array of the Verify V2 API. This means applications can deploy 2FA in a manner that best suits end-users' preferences.
Event and summary callbacks have been added, allowing for a multitude of integration and customization opportunities. Event callbacks offer unique end-users experiences, such as the WhatsApp Codeless channel. WhatsApp Codeless allows a user to authenticate without sending a one-time passcode. With no need to remember a code, the user simply presses "yes" or "no" in WhatsApp and an event callback is sent.
Unique Pricing Models
We are currently only charging for the channels that are used. There are no software or conversion fees, and do not bill for successful conversion. Specific to WhatsApp, billing is per WhatsApp message (business initiated pricing) plus the passthrough.
