Zero-Click Authentication Template

The Zero-Tap Authentication Template allows your users to receive one-time passwords or codes via WhatsApp without leaving your application.

When a user in your app requests a password or code and you provide that password or code using the Zero-Tap Authentication Template, the WhatsApp client simply broadcasts the included password or code, which your app can capture immediately using a broadcast receiver.

From the user's perspective, they request a password or code in your app, and it automatically appears in your app. If your app users happen to be viewing messages in the WhatsApp client, they will only see a message displaying the default pinned text: <code> is your verification code.

Like the One-Tap Autofill Button Authentication Template, when the WhatsApp client receives a template message containing the user's password or code, we perform a series of eligibility checks. If the message fails this check and we cannot broadcast the password or code, the message will display a One-Tap Autofill Button or Copy Code button. Therefore, when you create a Zero-Tap Authentication Template, you must include One-Tap Autofill and Copy Code buttons in the post body payload, even if the user may never see one of the buttons.

Limitations

Zero-Tap is only supported on Android. If you send a Zero-Tap Authentication Template to a WhatsApp user with a non-Android device, WhatsApp will display a Copy Code button.

URLs, media, and emojis are not supported.
