Kount Complete RIS Wrapper

Gem Version

Description

A fork of the official Kount Complete RIS wrapper (that is no longer being maitained). It provides simple methods to execute RIS calls.

Philosophy

The idea behind the kount_complete gem for Ruby is to provide an easy-to-configure wrapper to the transport layer for RIS. All interaction with the wrapper is done using native Ruby Hashes and Arrays instead of enforcing rigid getters and setters for every RIS element. This allows a merchant to integrate the gem using the current version and then easily access new functionality with the original gem as new RIS versions are released.

Installation

gem install kount_complete_2

Usage

require 'kount'
client = Kount.new(options)

Runtime Configuration

Create client object

Does not matter how you handle your config params (yaml/scripted/etc) so long as you provide the Kount class a hash with: :merchant_id, :ksalt, and :key. This minimal config will default to production settings.

options = {
  merchant_id: MERCHANT_ID,  #required (6 digit number, assigned by Kount)
  key:         KEY,          #required (created in the AWC web app by merchant)
  ksalt:       KSALT        #required (provided by Kount)
}
client = Kount.new(options)

There are additional params that are optional depending on your setup and environment (test, beta, other).

  • :is_test (defaults to false)
  • :endpoint (defaults to production value)
  • :version (defaults "0630")

When :is_test is omitted or set to false, the RIS endpoint will default to production values. When :is_test is set to true, the RIS endpoint will default to Kount test server settings; however, both endpoints can be overridden if needed.

The key required for RIS is defined by the merchant in the Kount AWC.

The :version is to specify which version of the RIS interface is being called. Newer interface versions might require additional paramaters in the client.get_response call and may also provide additional/different return parameters. Only change the :version if you know what you're doing.

Example RIS Calls

Inquiry (Mode Q)

client = Kount.new(options)

A hash can be provided during object creation:

inquiry = Kount::Inquiry.new(
    SITE: "DEFAULT",
    MACK: "Y",
    AUTH: "A",
    ORDR: "3458",
    TOTL: "5000",
    EMAL: "[email protected]"
    )

NOTE: The Kount::Inquiry.new() will automatically set the following params based on your configuration settings: :MERC, :MODE, :VERS and :FRMT.

Additional params can be added using a hash:

inquiry.add_params(CURR: "USD", IPAD: "127.0.0.1", SESS: "456789y0nn87tn")

The add_payment method is provided to encapsulate the KHASH logic for credit cards, gift cards and other payment types. It handles the setting of: :PTYP, :PTOK and :PENC when needed. Kount::PaymentTypes is a set of constants defined with supported payment types.

inquiry.add_payment(Kount::PaymentTypes::CREDIT_CARD, "4359873465893466783")

Every Inquiry (mode Q) requires cart data. Use the add_item and add_cart to simplify the conversion to form data. It handles the setting of: :PROD_TYPE, :PROD_DESC, :PROD_ITEM, :PROD_PRICE, and :PROD_QUANT

cart = Kount::Cart.new()

The params are: cart.add_item(Type, Description, Item, Quantity, Price)

cart.add_item('64 inch LCD TV', 'Electronics', 'Television', '1', '45')
cart.add_item('32 inch LCD TV', 'Electronics', 'Television', '44', '4564')
cart.add_item('48 inch Plasma TV', 'Electronics', 'Television', '8', '765476')
inquiry.add_cart(cart)

Just like with cart items, the form element formatting for UDFs can be tricky, so a quick convenience method is available on the Request class for adding them.

inquiry.add_udf('UDF_LABEL', 'UDF value')

The get_response is the first point at which the Kount server is contacted. Everything it needs to provide the response should be included in the inquiry payload. Response format is a native Ruby Hash.

response = client.get_response(inquiry)

Update (MODE U & X)

The Kount::Update.new() will automatically set the following params based on your configuration settings: :MERC, :MODE, :VERS and :FRMT. The default is MODE: 'U' for Kount::Update so MODE: 'X' will need to be added manually if you need mode X.

update = Kount::Update.new({
    TRAN: "30SP03DL69JS", # TRAN is one of the return values from a MODE Q call
    SESS: "456789y0n34b07y34n807yn87tn",
    MACK: "Y",
    AUTH: "D",
    ORDR: "3458",
    })
response = client.get_response(update)

Inquiry (MODE J & W)

The Kount::Inquiry.new() will automatically set the following params based on your configuration settings: :MERC, :VERS, and :FRMT. However, you will need to provide your desired :MODE setting since it will otherwise default to Q. Also required for both MODE J and W is the :CUSTOMER_ID param.

inquiry = Kount::Inquiry.new({
    MODE: "J",
    CUSTOMER_ID: "Customer 1",
    })
response = client.get_response(inquiry)

Inquiry (MODE P)

Just like MODE J and W, you will need to provide your desired :MODE setting since it will otherwise default to Q. Also required for MODE P is the :ANID param instead of the :CUSTOMER_ID param.

inquiry = Kount::Inquiry.new({
    MODE: "P",
    ANID: "9991230000", # Phone number
    })
response = client.get_response(inquiry)

KHASH

Convert Credit Card number to KHASH without RIS_KEY or Endpoint configuration

The only required option setting for credit card KHASH is the KSALT. The secret KSALT value is provided to clients only.

Kount::SecurityMash.hash_credit_card(plain_text, ksalt)

For the GIFT payment type, a merchant id is also required.

Kount::SecurityMash.hash_gift_card(plain_text, ksalt, merchant_id)
