    WhatsApp Zero Tap and One Tap Authentication Templates are now supported on Twilio

    Twilio adds one-tap autofill and zero-tap authentication templates for WhatsApp. Users can authenticate via a WhatsApp button that triggers your app, or receive OTPs directly in chat with a fallback if zero-tap fails. Docs explain configuration.

    Twilio now supports sending one tap and zero tap authentication templates on WhatsApp. One tap autofill lets your customers authenticate by clicking a button in WhatsApp that triggers an activity that opens your app and delivers the password or code to it. Zero tap authentication templates allow your users to receive one-time passwords or codes through WhatsApp without having to leave your app. If the zero-tap process fails, the code is still delivered in the WhatsApp chat. More information on how to configure your existing authentication or new templates to support this functionality can be found in our documentation.
