> An easy to use, consistent fraud prevention library for **PHP 7.1+**. Inspired by [Omnipay](https://github.com/thephpleague/omnipay).

Omnifraud is an ecommerce fraud prevention library for PHP. The project aims to provide a clear and consistent API for interacting with different fraud prevention, risk assessment, and liability shifting services.

Motivation
----------

[](#motivation)

There are a lot of risk assessment services out there and, although some details differ, the flow is almost always the same.

- Generate a random session ID
- Insert JavaScript tracking code into front end with aforementioned session ID
- On checkout, send a request to risk assessment service with session ID and order information

We created Omnifraud to satiate our own needs. The benefits of using the Omnifraud library are:

- Learn one interface, use throughout projects with different providers.
- Clean separation. Easily swap providers without touching a single line of checkout code.
- Documentation in popular risk assessment services isn't always clear. Put in your API key and go.

Installation
------------

[](#installation)

Usually all you'll need to do is install the service you need. For example:

```
composer require omnifraud/signifyd
```

Each package already requires [`omnifraud/common`](https://github.com/lxrco/omnifraud-common), so you don't need to require it.

To install **ALL** supported services:

```
composer require omnifraud/omnifraud
```
