This package provides an API for the MaxMind minFraud Score, Insights, Factors and Report Transaction web services.
We recommend installing this package with Maven. To do this, add the dependency to your pom.xml:
<dependency>
<groupId>com.maxmind.minfraud</groupId>
<artifactId>minfraud</artifactId>
<version>3.6.0-beta.1</version>
</dependency>Add the following to your build.gradle file:
repositories {
mavenCentral()
}
dependencies {
compile 'com.maxmind.minfraud:minfraud:3.6.0-beta.1'
}
API documentation is viewable on our GitHub Page under the API tab.
To use this API, first create a new WebServiceClient object. The constructor
takes your MaxMind account ID and license key as arguments. For example:
WebServiceClient client = new WebServiceClient.Builder(6, "ABCD567890").build();If you would like to use the Sandbox environment, you can use the host method
that belongs to the Builder. For example,
WebServiceClient client = new WebServiceClient.Builder(6, "ABCD567890")
.host("sandbox.maxmind.com").build();Then create a new Transaction object. This represents the transaction that
you are sending to minFraud. The class is instantiated using an inner builder
class, Transaction.Builder. Each builder method takes a corresponding
request model object. Each of these objects is similarly built up with
corresponding builder classes. For example:
Transaction transaction = new Transaction.Builder(
new Device.Builder(InetAddress.getByName("1.1.1.1")).build()
).email(
new Email.Builder()
.address("[email protected]")
.build()
).build();After creating the transaction object, send a Score request by calling the
score method:
ScoreResponse score = client.score(transaction);an Insights request by calling insights method:
InsightsResponse insights = client.insights(transaction);a Factors request by calling factors method:
FactorsResponse factors = client.factors(transaction);If the request succeeds, a model object will be returned for the endpoint. If the request fails, an exception will be thrown.
To report a transaction:
TransactionReport transaction = new TransactionReport.Builder(
InetAddress.getByName("1.1.1.1"), Tag.NOT_FRAUD
).build();
client.reportTransaction(transaction);reportTransaction() has a void return type. If the request fails, an
exception will be thrown.
See the API documentation for more details.
Runtime exceptions:
IllegalArgumentException- This will be thrown when an illegal argument is passed to a builder method. For instance, a country code that is not two capital letters.
Checked exceptions:
AuthenticationException- This will be thrown when the server is unable to authenticate the request, e.g., if the license key or account ID is invalid.InsufficientFundsException- This will be thrown when your account is out of funds.InvalidRequestException- This will be thrown when the server rejects the request for another reason such as invalid JSON in the POST.PermissionRequiredException- This will be thrown when permission is required to use the service.MinFraudException- This will be thrown when the server returns an unexpected response. This also serves as the base class for the above checked exceptions.HttpException-This will be thrown when an unexpected HTTP error occurs such as an internal server error or other unexpected status code.

System.out.println(client.insights(request));MaxMind encourages the use of this API, as data received through this channel is continually used to improve the accuracy of our fraud detection algorithms.
To use the Report Transactions API, create a new TransactionReport object. A
valid tag at least one of the following are required arguments: IP address,
MaxMind ID, minFraud ID, or transaction ID. Additional parameters may also be
set, as documented below.
If the report is successful, nothing is returned. If the report fails, an exception with be thrown.
See the API documentation for more details.
TransactionReport transaction = new TransactionReport.Builder(InetAddress.getByName("1.1.1.1"), Tag.NOT_FRAUD)
.chargebackCode("mycode")
.maxmindId("12345678")
.minfraudId(UUID.fromString("58fa38d8-4b87-458b-a22b-f00eda1aa20d"))
.notes("notes go here")
.transactionId("foo")
.build();
WebServiceClient client = new WebServiceClient.Builder(6, "ABCD567890").build();
client.reportTransaction(transaction);Please report all issues with this code using the GitHub issue tracker.
If you are having an issue with the minFraud service that is not specific to the client API, please see our support page.
This code requires Java 11+.
Patches and pull requests are encouraged. Please include unit tests whenever possible.
