2factor

2factor-node

NodeJS module for using the 2factor.in APIs for sending transactional and OTP sms in india

Installation

To install the library use

$ npm i 2factor --save

To install the library and save it as a dependency in package.json use

$ npm i 2factor --save

Usage

The module exports a constructor that returns new TwoFactor instances. The constructor expects the api key to be passed to it.

const TwoFactor = new (require('2factor'))(<your api key>)

Note - You shouldn't store your API key in your code or in text files you will commit to your repositories. Ideally, you want to use environment variables as given below -

let APIKEY = process.env.my_api_key || ''
if (APIKEY === '') {
  throw new Error('Missing 2Factor api key in environment')
}
const TwoFactor = new(require('2factor'))(APIKEY)

To get your balance -

The balance() method takes a single string parameter for the type of balance you want to retrieve. To get all balances, specify type as ALL or omit the parameter.

TwoFactor.balance().then((response) => {
  console.log(response)
}, (error) => {
  console.log(error)
})

To send an sms otp -

Simply call the sendOTP function with a phone number and options object containing the otp and template fields. It will return a Promise that resolves with the sessionId or reject with the reason for failure.

TwoFactor.sendOTP(<phone number>, {otp: <otp code>, template: <template_name>}).then((sessionId) => {
  console.log(sessionId)
}, (error) => {
  console.log(error)
})

To verify an sms otp -

Call verifyOTP() with the sessionId returned from the sendOTP function and the otp you want to check. If the otp was correct, it will resolve with a success message else it will reject with the response from 2Factor.in

TwoFactor.verifyOTP(sessionId, otp).then((response) => {
  console.log(response)
}, (error) => {
  console.log(error)
})

To send a template SMS to a single user

TwoFactor.sendTemplate('123456789', 'YOUR SENDER ID', ['VAR1','VAR2', 'VAR3']).then((response) => {
  console.log(response)
}, (error) => {
  console.log(error)
})

To send a template SMS to a single user

TwoFactor.sendTemplate(['123456789','987654321'], 'YOUR SENDER ID', ['VAR1','VAR2', 'VAR3']).then((response) => {
  console.log(response)
}, (error) => {
  console.log(error)
})
