By default, when the user enters a phone number, we'll send a verification code using SMS. You can add the option for your users to receive the verification code as a WhatsApp message.

How to Add the WhatsApp Option

In your config, add PhoneChannels attribute.

var config = {
  ...
  // Add WhatsApp option to send verification code
  PhoneChannels: ["SMS", "WHATSAPP"], // default = ["SMS"]
  
  // WhatsApp Button Styling
  ButtonWAText: "Continue with",
  ButtonWATextSubtitle:
    "Tell your customer that you'll be sending the verification code via WhatsApp",
  ButtonWABackgroundColor: "#128C7E",
  ButtonWABorderColor: "#075E54",
  ButtonWATextColor: "#ffffff",
  ButtonWALogoColor: "white",
};

WhatsApp Opt-In Requirements

WhatsApp requires that your application implement explicit user opt-ins to deliver messages over WhatsApp.

To do this, we provide the ButtonWATextSubtitle to explicitly inform your users that they will be receiving a verification code via WhatsApp.

The default value for ButtonWATextSubtitle is "If you choose to login with WhatsApp, we will send a WhatsApp message to this number with a verification code"
