README

The Keen IO API lets developers build analytics features directly into their apps.

Build Status

Installation with Composer

Changes

Please review the change log ( CHANGE.md ) before upgrading!

Usage

This client was built using Guzzle, a PHP HTTP client & framework for building RESTful web service clients.

When you first create a new KeenIOClient instance you can pass configuration settings like your Project ID and API Keys in an array to the factory method. These are optional and can be later specified through Setter methods.

For certain API Resources, the Master API Key is required and can also be passed to the factory method in the configuration array. Please read the Security Documentation regarding this Master API key.

For Requests, the KeenIOClient will determine what API Key should be passed based on the type of Request and configuration in the Service Description. The API Key is passed in the Authorization header of the request.

For a list of required and available parameters for the different API Endpoints, please consult the Keen IO API Reference Docs.

Configuring the Client

The factory method accepts an array of configuration settings for the Keen IO Webservice Client.

Setting Property Name Description Project ID projectId The Keen IO Project ID for your specific project Master API Key masterKey The Keen IO Master API Key - the one API key to rule them all Read API Key readKey The Read API Key - used for access to read only GET or HEAD operations of the API Write API Key writeKey The Write API Key - used for write PUT or POST Requests operations of the API API Version version The API Version. Currently used to version the API URL and Service Description

When passing version to the factory method or using the setVersion() method, the Client will try to load a client Service Description that matches that version. That Service Description defines the operations available to the Webservice Client.

Currently the Keen IO Webservice Client only supports - and automatically defaults - to the current version (3.0) of the API.

Example
use KeenIO\Client\KeenIOClient;

$client = KeenIOClient::factory([
    'projectId' => $projectId,
    'writeKey'  => $writeKey,
    'readKey'   => $readKey
]);
Configuration can be updated to reuse the same Client:

You can reconfigure the Keen IO Client configuration options through available getters and setters. You can get and set the following options: projectId, readKey, writeKey, masterKey, & version.

Example
//Get the current Project Id
$client->getProjectId();

//Set a new Project Id
$client->setProjectId($someNewProjectId);

//Get the current Read Key
$client->getReadKey();

//Set a new Read Key
$newReadKey = $client->createScopedKey($filters, $allowedOperations);
$client->setReadKey($newReadKey);
Send an event to Keen - (Changed in 2.0!)

Once you've created a KeenIOClient, sending events is simple:

Example
$event = ['purchase' => ['item' => 'Golden Elephant']];

$client->addEvent('purchases', $event);
Send batched events to Keen - (Changed in 2.0!)

You can upload multiple Events to multiple Event Collections at once!

In the example below, we will create two new purchase events in the purchases event collection and a single new event in the sign_ups event collection. Note that the keys of the data array specify the event_collection where those events should be stored.

Example
$purchases = [
    ['purchase' => ['item' => 'Golden Elephant']],
    ['purchase' => ['item' => 'Magenta Elephant']]
];
$signUps = [
    ['name' => 'foo', 'email' => 'bar@baz.com']
];

$client->addEvents(['purchases' => $purchases, 'sign_ups' => $signUps]);
Get Analysis on Events

All Analysis Endpoints should be supported. See the API Reference Docs for required parameters. You can also check the Service Description for configured API Endpoints.

Below are a few example calls to some of the Analysis methods available.

Note: Once the API acknowledges that your event has been stored, it may take up to 10 seconds before it will appear in query results.

Example
//Count
$totalPurchases = $client->count('purchases');

//Count Unqiue
$totalItems = $client->countUnique('purchases', ['target_property' => 'purchase.item']);

//Select Unique
$items = $client->selectUnique('purchases', ['target_property' => 'purchase.item']);

//Multi Analysis
$analyses = [
    'clicks'        => ['analysis_type' => 'count'],
    'average price' => ['analysis_type' => 'average', 'target_property' => 'purchase.price']
];
$stats = $client->multiAnalysis('purchases', ['analyses' => $analyses]);

//Using Filters in your Analysis
$filters = [
    ['property_name' => 'item.price', 'operator' => 'gt', 'property_value' => 10]
];

$client->count('purchases', ['filters' => $filters]);
Create a Scoped Key

Scoped keys allow you to secure the requests to the API Endpoints and are especially useful when you are providing access to multiple clients or applications. You should read the Keen IO docs concerning Scoped Keys for more details.

Example
$filter = [
    'property_name'  => 'user_id',
    'operator'       => 'eq',
    'property_value' => '123'
];

$filters = [$filter];
$allowedOperations = ['read'];

$scopedKey = $client->createScopedKey($filters, $allowedOperations);
