This document contains resources for the Kount Python SDK. The Kount RIS Python SDK provides information about:
- Building and sending requests to the RIS service
- Customer-side data verification
- Sensitive information protection
Installing the RIS Python SDK
Kount recommends using the pip package manager pip install kount_ris_sdk
to install the latest RIS Python SDK. Kount allows developers to download the SDK library from the Python SDK GitHub repository; however, Kount recommends using pip.
Follow the steps below to download from the SDK library:
- Clone the SDK repository to your machine.
- Use your preferred Git client
- Console:
git clone https://github.com/Kount/kount-ris-python-sdk.git
git clone git@github.com:Kount/kount-ris-python-sdk.git - Use your preferred python IDE.
Configuring the RIS Python SDK
Before you make your RIS call, you need to have received (or created) the following data from Kount:
- Merchant ID: 6-digit integer, referenced as
MERCHANT_ID
in code snippets - Site ID: DEFAULT (if custom Site IDs are being used, contact your Kount implementation engineer)
- RIS POST URL (in test): https://risk.test.kount.net in
test_api_kount.py
- API Key: Used to authenticate the RIS POST, refer to How to Create an API Key for Authentication to Kount to create an API key in the AWC
- KHASH ConfigKey: If applicable to integration, contact your Kount implementation engineer to obtain this
ConfigKey
, which is used to hash card data
Making Your First Call
There are two types of requests that can be performed through the SDK: Inquiry and Update. The usual structure of a Request usually consists of three parts:
- Information about the merchant and processing instructions for the RIS service
- Information about the customer making a purchase: personal data, geo-location, etc.
- Information about the purchase: product name, category, quantity, price
Example of an Inquiry object being sent to the RIS service /see test_inquiry.py/
.
#python from kount.util.khash import Khash from kount.settings import configurationKey as iv Khash.set_iv(iv) MERCHANT_ID = 999667 EMAIL_CLIENT = "customer.name@email.com" SHIPPING_ADDRESS = Address("567 West S2A1 Court North", "", "Gnome", "AK", "99762", "US") PTOK = "0007380568572514" SITE_ID = "192.168.32.16" URL_API = "https://kount.ris/url" API_KEY = "real api key" def evaluate_inquiry(): session_id = generate_unique_id()[:32] inquiry = Inquiry() # set merchant information, see default_inquiry() in test_basic_connectivity.py inquiry.merchant_set(MERCHANT_ID) inquiry.request_mode(INQUIRYMODE.DEFAULT) inquiry.merchant_acknowledgment_set(MERCHANTACKNOWLEDGMENT.TRUE) inquiry.website("DEFAULT") #~ set customer information inquiry.unique_customer_id(session_id[:20]) inquiry.ip_address(SITE_ID) payment = CardPayment(PTOK, khashed=False) # credit-card-number #~ or for khashed token #~ payment = CardPayment(PTOK) # credit-card-number, khashed=True *default value* inquiry.payment_set(payment) inquiry.customer_name("SdkTestFirstName SdkTestLastName") inquiry.email_client(EMAIL_CLIENT) inquiry.shipping_address(SHIPPING_ADDRESS) # set purchase information inquiry.currency_set(CURRENCYTYPE.USD) inquiry.total_set('123456') cart_item = [] cart_item.append(CartItem("SPORTING_GOODS", "SG999999", "3000 CANDLEPOWER PLASMA FLASHLIGHT", '2', '68990')) inquiry.shopping_cart(cart_item) client = Client(URL_API, API_KEY) response = client.process(params=self.inq.params) response_params = Response(response).params # do stuff with response
Request Explanation
Here is a short description of the request creation process.
- Creating the communication client, requires the RIS service URL and provided API key. The API key is set as request header for the network request.
- Setting the request mode. As mentioned previously, there are several request modes and
INQUIRYMODE.INITIAL_INQUIRY
is the most used one. - Setting a session identifier. This ID should be unique for a 30-day span and is used to track all changes regarding the purchase described in the request.
- IP address of the customer. The merchant can discover it or it can be obtained through the Device Data Collector service.
- Set this to a correct credit number or select another payment method (for test purposes).
- The total purchase amount represented in the lowest possible currency denomination (example: cents for US Dollars)
- Different payment types
/user defined/
can be created with NewPayment or Payment:
NewPayment(payment_type="PM42", payment_token=token) # default khashed=True Payment("PM42", token, False) Payment("PM42", token) # default khashed=True
RIS Response
After a merchant has posted RIS information to Kount, a key-value pair string is returned back to the merchant. The RIS response format is the same that was specified in the RIS request, with the default being named pairs. Each data field must be invoked by getter methods on the Response object from the SDK. The merchant can then use the RIS response to automate the order management process by keying off of the AUTO field and can utilize any of the additional data returned for internal processing.
An important use of the RIS response is the ability to view any warnings or errors that were made during the RIS post from the merchant. All warnings will be displayed in the response and if errors do occur the RIS response will be returned with a MODE = E /if inquiry.params["FRMT"] is not set/ or {"MODE": "E", "ERRO": "201"}
/if inquiry.params["FRMT"] = "JSON"/
. A Response.get_errors()
returns an error list.
RIS Payment Encryption Options
The Kount RIS Python SDK defines a group of objects representing various payment types. Using those payment types with the Request.set_payment(...)
method automatically sets the required PTYP parameter and other parameters corresponding to the selected payment type.
Supported payment types:
- CardPayment
- CheckPayment
- GiftCardPayment
- GooglePayment
- GreenDotMoneyPakPayment
- PaypalPayment
- Apple Pay
- BPAY
- Carte Bleue
- ELV
- GiroPay
- Interac
- Mercado Pago
- Neteller
- POLi
- Single Euro Payments Area
- Skrill/Moneybookers
- Sofort
- Token
There are also several "system" payment types:
- NoPayment
- BillMeLaterPayment
Request Types and Parameters
The two major request types, Inquiry and Update, are configured by setting the MODE parameter to the correct value.
Use Inquiry for initial registration of the purchase in the Kount system. It has four available values for the MODE
parameter:
Inquiry MODE | SDK Constant | Description |
---|---|---|
Q |
InquiryType.ModeQ |
Default inquiry mode, internet order type |
P |
InquiryType.ModeP |
Used to analyze a phone-received order |
W |
InquiryType.ModeW |
Kount Central full inquiry with returned thresholds |
J |
InquiryType.ModeJ |

Inquiry.setCart(collection<CartItem> cart)
method. If the shopping cart contains more than one entry, values for each parameter are transformed to single concatenated strings and then set to the corresponding parameter.Optional Parameters
Kount's RIS provides many optional request parameters to increase precision when making a decision about a given purchase/order.
AUTH
: Authorization Status returned to merchant from processor. Acceptable values for theAUTH
field areA
for Authorized orD
for Decline. In orders whereAUTH = A
will aggregate towards order velocity of the persona while orders whereAUTH = D
will decrement the velocity of the persona.AVST
: Address Verification System Street verification response returned to merchant from processor. Acceptable values areM
for match,N
for no-match, orX
for unsupported or unavailable.AVSZ
: Address Verification System Zip Code verification response returned to merchant from processor. Acceptable values areM
for match,N
for no match, orX
for unsupported or unavailable.CVVR
: Card Verification Value response returned to merchant from processor. Acceptable values areM
for match,N
for no-match, orX
unsupported or unavailable.LAST4
: Last 4 numbers of Credit Card Value.LBIN
: Captures 6-8 characters of BIN data
User Defined Fields (UDFs)
You can create User Defined Fields (UDFs) to include additional information related to your business that is not a standard field in the Transactions Details page in the AWC. Once you have defined the UDF in the AWC, you can pass this data into Kount via an array called UDF as key-value pairs where the label is the key and the data passed in is the value. For more information on creating UDF, review How to Manage User Defined Fields (UDF).
Session related parameters
There are a few parameters responsible for maintaining connection between linked interactions with the RIS. They are transported as a part of the Request/Response objects during standard RIS communication.
SESS parameter
This parameter should be created by the merchant at the start of each new customer purchase. SESS is used to join the customer device data with the order data sent with the RIS request. If the merchant uses the Device Data Collector service to obtain customer device information, then the same SESS value must be used for all RIS calls starting with the one to the Device Data Collector service. Requirements for the parameter value are:
- Alphanumeric
- 1-32 characters
- Value should be unique over a thirty-day period of time SESS is a mandatory parameter set by
Request.session_set(string)
method.
TRAN parameter
The TRAN parameter is required for Update calls to Kount RIS. Its value is created by Kount and is returned within the Response object for the first RIS Inquiry. For all subsequent events, modifying this particular customer order, the TRAN parameter should be set to the Kount-created value.
