minFraud Score, Insights, and Factors Python API¶
Beta Note¶
This is a beta release. The API may change before the first production release.
You may find information on the changes in minFraud Score, Insights, and Factors in our What’s New documentation.
Description¶
This package provides an API for the MaxMind minFraud Score, Insights, Factors web services.
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 .
Usage¶
To use this API, create a new minfraud.Client
object. The constructor
takes your MaxMind user ID and license key:
>>> client = Client(42, 'licensekey')
The Factors service is called with the factors()
method:
>>> factors = client.factors({'device': {'ip_address': '81.2.69.160'}})
The Insights service is called with the insights()
method:
>>> insights = client.insights({'device': {'ip_address': '81.2.69.160'}})
The Score web service is called with the score()
method:
>>> insights = client.insights({'device': {'ip_address': '81.2.69.160'}})
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.
The ip_address
in the device
sub-dictionary is required. All other
fields are optional.
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 user ID is invalid.minfraud.InsufficientFundsError
- This will be raised when your account is out of funds.minfraud.InvalidRequestError
- This will be raised when the server rejects the request as invalid for another reason, such as a missing or 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.
