minFraud Score, Insights, Factors and Report Transaction Python 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 minfraudIf 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.
