- Robust optional template features for WhatsApp messages:  The Template Management tool allows you to create templates that can include header with text or media. You can add a text-based footer, up to two call-to-action buttons, as well as interactive messages with up three quick reply buttons.
- New WhatsApp OTP copy code template:  A copy code authentication template allows you to send a one-time passcode (OTP) along with a copy code button to your end-users. When a WhatsApp user taps the copy code button, WhatsApp copies the passcode to the clipboard of the end-user's device. The end-user can then switch to your app and paste the passcode into the app.
- New WhatsApp OTP one-tap template available for Android apps A one-tap autofill authentication template allows you to send a one-time passcode (OTP) along with an Autofill button to your end users. When an end user taps the Autofill button, the WhatsApp client triggers an activity which opens the end user's app and delivers the password or code to the app.
- New WhatsApp OTP zero-tap template available for Android apps A zero-tap authentication template allows end users to receive one-time passwords or codes via WhatsApp without having to leave your app. When an end user using your app requests a password or code and we deliver it using zero-tap authentication. From end user's perspective, they request a password or code in your app and it appears in the app automatically.
