Sift Bindings

Installation

With Composer

1. Add siftscience/sift-php as a composer dependency

composer require siftscience/sift-php

2. Now SiftClient will be autoloaded into your project.

require 'vendor/autoload.php';

$sift = new SiftClient([
    'api_key' => 'my_api_key',
    'account_id' => 'my_account_id'
]);

// or

Sift::setApiKey('my_api_key');
Sift::setAccountId('my_account_id');
$sift = new SiftClient();

Manually

1. Download the latest release.

2. Extract into a folder in your project root named "sift-php".

3. Include SiftClient in your project like this:

   require 'sift-php/lib/SiftRequest.php';
   require 'sift-php/lib/SiftResponse.php';
   require 'sift-php/lib/SiftClient.php';
   require 'sift-php/lib/Sift.php';
   
   
   $sift = new SiftClient([
       'api_key' => 'my_api_key',
       'account_id' => 'my_account_id'
   ]);

Usage

Track an event

Here's an example that sends a $transaction event to sift.

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->track('$transaction', [
    '$user_id' => '23056',
    '$user_email' => 'buyer@gmail.com',
    '$seller_user_id' => '2371',
    '$transaction_id' => '573050',
    '$currency_code' => 'USD',
    '$amount' => 15230000,
    '$time' => 1327604222,
    'seller_user_email' => 'seller@gmail.com',
    'trip_time' => 930,
    'distance_traveled' => 5.26,
]);

Label a user as good/bad

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->label('23056', [
    '$is_bad' => true,
    '$abuse_type' => 'promotion_abuse'
]);

Unlabel a user

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->unlabel('23056', ['abuse_type' => 'content_abuse']);

Get a user's score

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->score('23056');
$response->body['scores']['payment_abuse']['score']; // => 0.030301357270181357

Get the status of a workflow run

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->getWorkflowStatus('my_run_id');
$response->body['state']; // => "running"

Get the latest decisions for a user

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->getUserDecisions('example_user');
$response->body['decisions']['account_abuse']['decision']['id']; // => "ban_user"

Get the latest decisions for an order

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->getOrderDecisions('example_order');
$response->body['decisions']['payment_abuse']['decision']['id']; // => "ship_order"

Get the latest decisions for a session

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->getSessionDecisions('example_user', 'example_session');
$response->body['decisions']['account_takeover']['decision']['id']; // => "session_decision"

List of configured Decisions

Optional Params

• entity_type: user or order or session
• abuse_types: ["payment_abuse", "content_abuse", "content_abuse", "account_abuse", "legacy", "account_takeover"]

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $this->client->getDecisions(['entity_type' => 'example_entity_type','abuse_types' => 'example_abuse_types']);
$response->isOk()

Apply decision to a user

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->applyDecisionToUser('example_user','example_decision','example_source',['analyst' => 'analyst@example.com']
$response->isOk()

Apply decision to an order

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->applyDecisionToOrder('example_user','example_order','example_decision','example_source',['analyst' => 'analyst@example.com']
$response->isOk()

Apply decision to a session

$sift = new SiftClient(['api_key' => 'my_api_key', 'account_id' => 'my_account_id']);
$response = $sift->applyDecisionToSession('example_user','example_session','example_decision','example_source',['analyst' => 'analyst@example.com']
$response->isOk()

Contributing

Run the tests from the project root with PHPUnit like this:

composer update
composer exec phpunit -v -- --bootstrap vendor/autoload.php test

Updating Packagist

1. Update composer.json to reflect the new version, as well as any new requirements then merge changes into master.

2. Create a new release with the version number and use it as the description. Packagist will automatically deploy a new package via the configured webhook.

HTTP connection pooling

You can substantially improve the performance of SiftClient by using HTTP connection pooling. Because standard PHP/fastcgi deployments don't have a mechanism for persisting connections between requests, the easiest way to pool connections is by routing requests through a proxy like Apache httpd or nginx.

Apache httpd

Listen 8081

...

LoadModule proxy_module .../mod_proxy.so
LoadModule proxy_http_module .../mod_proxy_http.so
LoadModule ssl_module .../mod_ssl.so

<VirtualHost localhost:8081>
    ServerName api.sift.com
    SSLProxyEngine on
    SSLProxyVerify require
    SSLProxyVerifyDepth 3
    SSLProxyCACertificateFile ...
    ProxyPass / https://api.sift.com/
</VirtualHost>

nginx

# Read more about nginx keepalive: https://www.nginx.com/blog/tuning-nginx/#keepalive
upstream sift {
    server api.sift.com:443;
    keepalive 16;
}

server {
    listen localhost:8081;
    server_name api.sift.com;

    location / {
        proxy_pass https://sift;
        proxy_http_version 1.1;
        proxy_set_header Connection "";
        proxy_ssl_verify on;
        proxy_ssl_verify_depth 3;
        proxy_ssl_trusted_certificate ...;
        proxy_ssl_name api.sift.com;
        proxy_ssl_server_name on;
    }
}

For Debian-based distributions, the certificate file is /etc/ssl/certs/ca-certificates.crt

Then, instantiate SiftClient to route requests through the proxy:

$sift = new SiftClient([
    'api_key' => 'my_api_key',
    'account_id' => 'my_account_id',
    'api_endpoint' => 'http://api.sift.com',
    'curl_opts' => [CURLOPT_CONNECT_TO => ['api.sift.com:80:localhost:8081']],
]);
