If your mobile app offers users the option to receive one-time passwords or verification codes via the WhatsApp app or WhatsApp Business app, you must use an authentication template with a one-time password button (OTP) to deliver the password or code.
If you want to create the authentication template via Templates API, you need to provide the WhatsApp Business Account ID (WABA) or the unique identifier of the sender.
To know how to create an authentication template go to the Creating & Sending Authentication WhatsApp Template section.
