Building an xAPI Client
=======================
The xAPI client library ships with a builder class which eases the process of
creating an instance of an ``XApiClient`` class:
```php
use Xabbuh\XApi\Client\XApiClientBuilder;
$builder = new XApiClientBuilder();
$xApiClient = $builder->setBaseUrl('http://example.com/lrs/api')
->setVersion('1.0.0')
->build();
```
The builder creates a client for the 1.0.1 API version if you don't set a version.
HTTP Basic Authentication
-------------------------
Use the ``setAuth()`` method if access to the LRS resources is protected with
HTTP Basic authentication:
```php
use Xabbuh\XApi\Client\XApiClientBuilder;
$builder = new XApiClientBuilder();
$xApiClient = $builder->setBaseUrl('http://example.com/lrs/api')
->setAuth('username', 'password')
->build();
```
OAuth1 Authentication
---------------------
Using the ``setOAuthCredentials()`` method, you can configure the client to
access OAuth1 protected resources:
```php
use Xabbuh\XApi\Client\XApiClientBuilder;
$builder = new XApiClientBuilder();
$xApiClient = $builder->setBaseUrl('http://example.com/lrs/api')
->setOAuthCredentials('consumer-key', 'consumer-secret', 'token', 'token-secret')
->build();
```
Using the APIs
--------------
The Experience API consists of four sub APIs: the statements API, the state API,
the activity profile API and the agent profile API. A client for each of these
APIs can be obtained from the global ``XApiClient`` instance:
```php
$statementsApiClient = $xApiClient->getStatementsApiClient();
$stateApiClient = $xApiClient->getStateApiClient();
$activityProfileApiClient = $xApiClient->getActivityProfileApiClient();
$agentProfileApiClient = $xApiClient->getAgentProfileApiClient();
```
Read the dedicated chapters of the sub APIs to learn how to make use of them:
1. [The Statements API](statements.md)
1. [The State API](state.md)
1. [The Activity Profile API](activity_profile.md)
1. [The Agent profile API](agent_profile.md)
