minfraud 2.3.1

MaxMind minFraud Score, Insights, Factors and Report Transactions API

Description

This package provides an API for the MaxMind minFraud Score, Insights, and Factors web services as well as the Report Transaction web service.

Installation

To install the minfraud module, type:

$ pip install minfraud

If you are not able to use pip, you may also use easy_install from the source directory:

$ easy_install .

Documentation

Complete API documentation is available on Read the Docs.

Usage

To use this API, create a new minfraud.Client object for a synchronous request or minfraud.AsyncClient for an asynchronous request. The constructors take your MaxMind account ID and license key:

>>> client = Client(42, 'licensekey')
>>> async_client = AsyncClient(42, 'licensekey')

Score, Insights and Factors Usage

The Factors service is called with the factors() method:

>>> client.factors({'device': {'ip_address': '152.216.7.110'}})
>>> await async_client.factors({'device': {'ip_address': '152.216.7.110'}})

The Insights service is called with the insights() method:

>>> client.insights({'device': {'ip_address': '152.216.7.110'}})
>>> await async_client.insights({'device': {'ip_address': '152.216.7.110'}})

The Score web service is called with the score() method:

>>> client.score({'device': {'ip_address': '152.216.7.110'}})
>>> await async_client.score({'device': {'ip_address': '152.216.7.110'}})

Each of these methods takes a dictionary representing the transaction to be sent to the web service. The structure of this dictionary should be in the format specified in the REST API documentation. All fields are optional.

Report Transactions Usage

MaxMind encourages the use of this API as data received through this channel is used to continually improve the accuracy of our fraud detection algorithms. The Report Transaction web service is called with the report() method:

>>> client.report({'ip_address': '152.216.7.110', 'tag': 'chargeback'})
>>> await async_client.report({'ip_address': '152.216.7.110', 'tag': 'chargeback'})

The method takes a dictionary representing the report to be sent to the web service. The structure of this dictionary should be in the format specified in the REST API documentation. The ip_address and tag fields are required. All other fields are optional.

Request Validation (for all request methods)

Assuming validation has not been disabled, before sending the transaction to the web service, the transaction dictionary structure and content will be validated. If validation fails, a minfraud.InvalidRequestError will be raised.

If the dictionary is valid, a request will be made to the web service. If the request succeeds, a model object for the service response will be returned. If the request fails, one of the errors listed below will be raised.

Errors

The possible errors are:

• minfraud.AuthenticationError - This will be raised when the server is unable to authenticate the request, e.g., if the license key or account ID is invalid.

• minfraud.InvalidRequestError - This will be raised when the server rejects the request as invalid for another reason, such as a reserved IP address. It is also raised if validation of the request before it is sent to the server fails.

• minfraud.HttpError - This will be raised when an unexpected HTTP error occurs such as a firewall interfering with the request to the server.

• minfraud.MinFraudError - This will be raised when some other error occurs such as unexpected content from the server. This also serves as the base class for the above errors.

Additionally, score, insights and factors may also raise:

• minfraud.InsufficientFundsError - This will be raised when your account is out of funds.

Report Transactions Example

For synchronous reporting:

>>> from minfraud import Client
>>>
>>> with Client(42, 'licensekey') as client
>>>     transaction_report = {
>>>         'ip_address': '152.216.7.110',
>>>         'tag': 'chargeback',
>>>         'minfraud_id': '2c69df73-01c0-45a5-b218-ed85f40b17aa',
>>>      }
>>>      client.report(transaction_report)

For asynchronous reporting:

>>> import asyncio
>>> from minfraud import AsyncClient
>>>
>>> async def report():
>>>     async with AsyncClient(42, 'licensekey') as client
>>>         transaction_report = {
>>>             'ip_address': '152.216.7.110',
>>>             'tag': 'chargeback',
>>>             'minfraud_id': '2c69df73-01c0-45a5-b218-ed85f40b17aa',
>>>          }
>>>          await async_client.report(transaction_report)
>>>
>>> asyncio.run(report())
