Kount Access API Library for Node.js

Overview

This package contains a node.js library to utilize the API services of Kount's Access Product. For more information on what Kount Access is, go to http://www.kount.com

Installing

The easiest way to install kount-access is using npm:

npm install kount-access-api

You can also download the latest from github:

https://github.com/Kount/access-api-clients/nodejs/kount-access.git

Usage

In your node.js application add the require for this package:

var kount = require('kount-access-api')

Ensure you have the information needed to instantiate the library in your app.

• merchantId - The merchant ID provided to you from Kount.
• apiKey - the API key you generated from kount (or was provided to you)
• serverName - The DNS name of the server you want to connect to. These are also provided by merchant services. You should have one server assigned for testing and one for production.
• version - The version of the API to access (defaults to the current version "0200"). The version is in the form of a 4 digit string

In your application it should look something like this:

//Replace with your merchant Id
var merchantId = 123456
var apiKey = 'YOUR-API-KEY-GOES-HERE'
var serverName = 'someserver.kountaccess.com'
var version = '0200' //Optional

Then create an instance of the Library interface:

var ka = new kount.KountAccessApiLibrary(merchantId, apiKey, serverName, version)

Now you are ready to call the API Services.

In the /example directory there is a referenceImplementation.js that can walk you through each of the API calls. However to use the example, you will need to npm install prompt and update the merchantId, apiKey, serverName, and sessionId fields.

npm install prompt

###getDevice

If you are just looking for information about the device (like the device id, or pierced IP Address) The use the getDevice() function. This example shows how to get device info and what it would look like as a json array.

Required minimum Kount Access API version: 0103

Required Fields:

• sessionId - This is a value passed to the Kount Access' Data Collector on your login page.
• callback - Callback function to return the information you are looking for in the form of callback(error, data). This follows standard Node.js callback functionality. The Data value (when valid) will be a JSON object (associative array).

Code example:

response = ka.getDevice(sessionId, function (err, data) {
    if (err !== null) {
        console.log("Error:" + err)
    } else {
        console.log(data)
    }
})

Sample"data" value:

{ "device":
    { "mobile": 0,
      "country": "US",
      "region": "ID",
      "ipGeo": "US",
      "proxy": 0,
      "ipAddress": "64.128.91.251",
      "id": "0cbf8913c671cb0f736c5636d2a4be28"
    },
  "response_id": "4a326720df188e65134e4d8a85fc5531"
}

For more information about the fields in the request or response, please see the API Documentation for the Version you are interested in.

###getVelocity If you want to know about the velocity of your users or devices as it pertains to other data points, you would want to call getVelocity(). This allows you to see the relationships between the following pieces of information over a period of time:

• Devices
• IP Addresses
• Usernames
• Passwords
• Accounts

The Device information is also included in this response in addition to the velocity information. You can use this velocity information in your own decisioning engine. The service also re-hashes the account information before pushing it over HTTPS just in case you forgot to.

Required minimum Kount Access API version: 0103

Required Fields:

• sessionId - This is a value passed to the Kount Access' Data Collector on your login page.
• userHash - This is a hashed value of the username used for login
• passwordHash - This is a hashed value of the password used for login.
• callback - Callback function to return the information you are looking for in the form of callback(error, data). This follows standard Node.js callback functionality. The Data value (when valid) will be a JSON object (associative array).

Code example:

response = ka.getVelocity(sessionId, userHash, passwordHash, function (err, data) {
    if (err !== null) {
        console.log("Error:" + err)
    } else {
        console.log(data)
    }
})

Sample"data" value:

{"device": {"mobile": 0, "country": "US", "region": "ID", "ipGeo": "US", "proxy": 0, "ipAddress": "64.128.91.251", "id": "0cbf8913c671cb0f736c5636d2a4be28"}, "velocity": {"device": {"ulh": 1, "alm": 1, "alh": 1, "ulm": 1, "plm": 1, "iplh": 1, "iplm": 1, "plh": 1}, "account": {"ulh": 1, "iplh": 1, "iplm": 1, "ulm": 1, "plm": 1, "dlh": 1, "dlm": 1, "plh": 1}, "password": {"iplh": 1, "ulh": 1, "alm": 1, "iplm": 1, "alh": 1, "ulm": 1, "dlh": 1, "dlm": 1}, "ip_address": {"ulh": 1, "alm": 1, "alh": 1, "ulm": 1, "plm": 1, "dlh": 1, "dlm": 1, "plh": 1}, "user": {"iplh": 1, "alm": 1, "iplm": 1, "alh": 1, "plm": 1, "dlh": 1, "dlm": 1, "plh": 1}}, "response_id": "0a8f7366a2e50956fc4dee0220ad9ab0"}

###getDecision If you want Kount Access to evaluate possible threats using our Thresholds Engine, you will want to call the getDecision endpoint. This example shows how to call the decision call and what it would look like as an associative array. This response also includes device information and velocity data in addition to the decision information. The decision value can be either "A" - Approve, or "D" - Decline. In addition is will show the ruleEvents evaluated that forces a "D"(Decline) result. If you do not have any thresholds established it will always default to "A"(Approve). For more information on setting up thresholds, consult the User Guide.
