SendOtp - Node.js SDK

This SDK enables sendOTP and allows you to send OTP

Set-up:

1. Download the NPM module

npm install sendotp --save

2. Require the package in your code.

const SendOtp = require('sendotp');

3. Initialize with your MSG91 auth key

const sendOtp = new SendOtp('AuthKey');

That's all, your SDK is set up!

Requests

You now have the send, retry and verify otp via following methods.

sendOtp.send(contactNumber, senderId, otp, callback); //otp is optional if not sent it'll be generated automatically
sendOtp.retry(contactNumber, retryVoice, callback);
sendOtp.verify(contactNumber, otpToVerify, callback);

Note:

In callback function you'll get two parameters but you have to always listen for second param instead of direct error object. Error object sample code

{"type":"error","message":"ERROR_MESSAGE"}

Usage:

To send OTP, without optional parameters

sendOtp.send("919999999999", "PRIIND", function (error, data) {
  console.log(data);
});

To send OTP, with optional parameters

sendOtp.send("919999999999", "PRIIND", "4635", function (error, data) {
  console.log(data);
});

If you want to set custom expiry of OTP verification

sendOtp.setOtpExpiry('90'); //in minutes

To retry OTP

sendOtp.retry("919999999999", false, function (error, data) {
  console.log(data);
});

Note: In sendOtp.retry() set retryVoice false if you want to retry otp via text, default value is true

To verify OTP

sendOtp.verify("919999999999", "4365", function (error, data) {
  console.log(data); // data object with keys 'message' and 'type'
  if(data.type == 'success') console.log('OTP verified successfully')
  if(data.type == 'error') console.log('OTP verification failed')
});

Options:

By default sendotp uses default message template, but custom message template can also set in constructor like

const SendOtp = require('sendotp');
const sendOtp = new SendOtp('AuthKey', 'Otp for your order is {{otp}}, please do not share it with anybody');

{{otp}} expression is used to inject generated otp in message.
