Introduction

Vereafy is an SMS based 2-factor authentication service that uses machine learning to understand the causes of OTP delivery failures and resolves them instantly to ensure your login and sign up OTPs deliver.

The Vereafy Nodejs Library Project was created to enable nodejs developers integrate seamlessly with the Vereafy API.

How to use this library

• Install vereafy from npm or yarn following the instructions in the Installation section or clone from GitHub
• Login to the Cecula Developers Platform register your app and generate an API KEY
• Import/Require the library into your script

Installation

Install with NPM:

npm i vereafy

Install with Yarn:

yarn add vereafy

Clone from GitHub

git clone https://github.com/cecula-vereafy/nodejs-library.git

How to generate an API Key

Your API Key is first generated when you register an app. To register an app, Login to the Developers Dashboard, Navigate to Apps > Add, Type the name of your app and click Submit. The app will be registered and a new API Key will be generated. Copy the API key into your project

Importing Vereafy Library

If you installed the library using npm or yarn, import the library into your script using the code below

const vereafy = require("vereafy");
vereafy.apiKey = "<API_KEY>"

Otherwise, if you cloned the library from GitHub, import the library into your script using the code below

const vereafy = require("./path/to/vereafy");
vereafy.apiKey = "<API_KEY>"

Initializing 2FA

The Vereafy 2fa initialization can be as simple as the following lines of code:

    var sendData = {
        "mobile": "23480xxxxxxxx"
    };

    vereafy.init(senData,(res)=>{
        // If status is success show user form to type OTP
    });

The initialization method returns a response that should look like this:

   {
       "status": "success",
       "pinRef": "1293488527"
   }

Resending OTP

In a case where your app users get impatient and hits the retry link on your app form, just call the resend method this way:

   var sendData = {
       "pinRef": "1293488527",
       "mobile": "23480xxxxxxxx"
   };

   vereafy.resend(sendData, (res)=>{
       // If status is success, show user form to type OTP
   });

The resend method returns a response that should look like this:

    {
        "status": "success",
        "pinRef": "1293488527"
    }

Completing 2FA

The Vereafy 2fa completion can be as simple as the following lines of code:

    var sendData = {
        "pinRef": "1293488527",
        "token": "123456"
    }
    vereafy.complete(sendData, (res)=>{
        // Handle failure or success response
    })

The completion method returns a response that should look like this if the parameters are correct:

    {
        "response": "success"
    }

Getting Balance

To get your balance on Vereafy, the getBalance method is used this way: This method requires no parameter:

    vereafy.getBalance((res)=>{
        // Do Something
    })

The get balance method returns a response that should look like:

    {
        "balance": 800
    }

Error Responses

In a case where the request fails due to one reason or another you should get an error response from the requested endpoint that looks like this:

        {
            "error": "Invalid PIN Ref",
            "code": "CE2000"
        }
