How to send OTP codes with WhatsApp using Node.js

For sending OTP (One-Time Password) codes to clients with WhatsApp using Node.js pretty simple! For that we need only one library which is named auth-verify

npm install auth-verify

Initialize auth-verify

We need to configure our WhatsApp phone number for sending OTP codes.

const AuthVerify = require("auth-verify");
const auth = new AuthVerify();

// configuring whatsapp
auth.otp.sender({
   via: "whatsapp",
   phoneId: "YOUR_PHONE_ID",
   token: "YOUR_WHATSAPP_TOKEN"
});

Sending OTP codes to the users

For sending you need to only send() method from auth-verify:

auth.otp.send("RECIEVER_PHONE", {text: `Your OTP code is ${auth.otp.code}`}, (err, info)=> {
    if(err) console.log(err);
    else console.log(info);
});

Verfiying the OTP code

For verifying it you should use verify() method:

auth.otp.verify("RECIEVER_PHONE", "123456", (err, success) => {
    if(err) console.error(err.message);
    else console.log("✅ OTP verified");
});

});

auth.otp.send("RECIEVER_PHONE", {text: `Your OTP code is ${auth.otp.code}`}, (err, info)=> {
    if(err) console.log(err);
    else console.log(info);
});
