This package provides an API for the MaxMind minFraud Score, Insights, and Factors web services.
We recommend installing this package with Composer.
To download Composer, run in the root directory of your project:
curl -sS https://getcomposer.org/installer | phpYou should now have the file composer.phar in your project directory.
Run in your project root:
php composer.phar require maxmind/minfraud:~1.0
You should now have the files composer.json and composer.lock as well as
the directory vendor in your project directory. If you use a version control
system, composer.json should be added to it.
After installing the dependencies, you need to require the Composer autoloader from your code:
require 'vendor/autoload.php';Although we strongly recommend using Composer, we also provide a phar archive containing most of the dependencies for this API. The latest phar archive is available on our releases page.
Please note that you must have the PHP cURL
extension installed to use this
archive. For Debian based distributions, this can typically be found in the
the php-curl package. For other operating systems, please consult the
relevant documentation. After installing the extension you may need to
restart your web server.
If you are missing this extension, you will see errors like the following:
PHP Fatal error: Uncaught Error: Call to undefined function MaxMind\WebService\curl_version()
To use the archive, just require it from your script:
require 'minfraud.phar';More detailed API documentation is available on our GitHub Page under the "API" tab.
To use this API, create a new \MaxMind\MinFraud object. The constructor
takes your MaxMind account ID, license key, and an optional options array as
arguments. This object is immutable. You then build up the request using the
->with* methods as shown below. Each method call returns a new object. The
previous object is not modified.
If there is a validation error in the data passed to a ->with* method, a
\MaxMind\Exception will be thrown. This validation can be disabled by
setting validateInput to false in the options array for
\MaxMind\MinFraud, but it is recommended that you keep it on at least
through development as it will help ensure that you are sending valid data to
the web service.
After creating the request object, send a Score request by calling
->score(), an Insights request by calling ->insights(), or a Factors
request by calling ->factors(). If the request succeeds, a model object will
be returned for the endpoint. If the request fails, an exception will be
thrown.
See the API documentation for more details.
All externally visible exceptions are in the \MaxMind\Exception namespace.
The possible exceptions are:
InvalidInputException- This will be thrown when a->with*method is called with invalid input data or when->score()or->insights()is called on a request where the requiredip_addressfield in thedevicearray is missing.AuthenticationException- This will be thrown on calling->score()or->insights()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 on calling->score()or->insights()when your account is out of funds.InvalidRequestException- This will be thrown on calling->score()or->insights()when the server rejects the request for another reason such as invalid JSON in the POST.HttpException- This will be thrown on calling->score()or->insights()when an unexpected HTTP error occurs such as a firewall interfering with the request to the server.WebServiceException- This will be thrown on calling->score()or->insights()when some other error occurs. This also serves as the base class for the above exceptions.
