Maxmind minFraud Java API


This library is deprecated. Please use our minFraud Score, Insights, and Factors API.


We recommend installing this package with Maven. To do this, add the dependency to your pom.xml:


If you install by hand, you will need Apache HttpComponents.

Example programs

  • sample/ - how to use the API with minFraud service.

API Documentation for minFraud service

ccfs = new CreditCardFraudDetection(boolean s);

This creates a new CreditCardFraudDetection object and set isSecure to s if isSecure is false then it uses regular HTTP. if isSecure is true then it uses secure HTTPS.

ccfb = new CreditCardFraudDetection.Builder()

Additionally you can use the Builder object to create a CreditCardFraudDetection instance that either uses the JVM settings for proxies (useSystemProxies()) or a custom proxy (specified by hostname and port, e.g. useProxy("host", 3128)).

Here is a full example:

ccfs =  new CreditCardFraudDetection.Builder().
                useProxy("proxy-host", 6568).
ccfs.input(HashMap h);

Takes a Hashmap and uses it as input for the server See for details on input fields.


Queries the server with the fields passed to the input method and stores the output.

HashMap h = ccfs.output();

Returns the HashMap containing the output from the server. See for details on output fields.
