See [complete example](examples/) inside [index.php](examples/index.php) to get started.

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

[](#installation)

Use composer package manager

```
composer require zoonman/linkedin-api-php-client
```

Or add this package as dependency to `composer.json`.

If you have never used Composer, you should start [here](http://www.phptherightway.com/#composer_and_packagist)and install composer.

Usage
-----

[](#usage)

To start working with LinkedIn API, you will need to get application client id and secret.

Go to [LinkedIn Developers portal](https://developer.linkedin.com/)and create new application in section My Apps.

#### Bootstrapping autoloader and instantiating a client

[](#bootstrapping-autoloader-and-instantiating-a-client)

```
// ... please, add composer autoloader first
include_once __DIR__ . DIRECTORY_SEPARATOR . 'vendor' . DIRECTORY_SEPARATOR . 'autoload.php';

// import client class
use LinkedIn\Client;

// instantiate the Linkedin client
$client = new Client(
    'LINKEDIN_APP_CLIENT_ID',
    'LINKEDIN_APP_CLIENT_SECRET'
);
```

#### Getting local redirect URL

[](#getting-local-redirect-url)

To start linking process you have to setup redirect url. You can set your own or use current one. SDK provides you a `getRedirectUrl()` helper for your convenience:

```
$redirectUrl = $client->getRedirectUrl();
```

We recommend you to have it stored during the linking session because you will need to use it when you will be getting access token.

#### Setting local redirect URL

[](#setting-local-redirect-url)

Set a custom redirect url use:

```
$client->setRedirectUrl('http://your.domain.tld/path/to/script/');
```

#### Getting LinkedIn redirect URL

[](#getting-linkedin-redirect-url)

In order of performing OAUTH 2.0 flow, you should get LinkedIn login URL. During this procedure you have to define scope of requested permissions. Use `Scope` enum class to get scope names. To get redirect url to LinkedIn, use the following approach:

```
// define scope
$scopes = [
    'r_basicprofile',
    'r_emailaddress',
    'rw_company_admin',
    'w_share',
];
$loginUrl = $client->getLoginUrl($scopes); // get url on LinkedIn to start linking
```

Now you can take user to LinkedIn. You can use link or rely on Location HTTP header.

#### Getting Access Token

[](#getting-access-token)

To get access token use (don't forget to set redirect url)

```
$accessToken = $client->getAccessToken($_GET['code']);
```

This method returns object of `LinkedIn\AccessToken` class. You can store this token in the file like this:

```
file_put_contents('token.json', json_encode($accessToken));
```

This way of storing tokens is not recommended due to security concerns and used for demonstration purpose. Please, ensure that tokens are stored securely.

#### Setting Access Token

[](#setting-access-token)

You can use method `setAccessToken()` for the `LinkedIn\Client` class to set token stored as string. You have to pass instance of `LinkedIn\AccessToken` to this method.

```
use LinkedIn\AccessToken;
use LinkedIn\Client;

// instantiate the Linkedin client
$client = new Client(
    'LINKEDIN_APP_CLIENT_ID',
    'LINKEDIN_APP_CLIENT_SECRET'
);

// load token from the file
$tokenString = file_get_contents('token.json');
$tokenData = json_decode($tokenString, true);
// instantiate access token object from stored data
$accessToken = new AccessToken($tokenData['token'], $tokenData['expires_at']);

// set token for client
$client->setAccessToken($accessToken);
```

#### Performing API calls

[](#performing-api-calls)

All API calls can be called through simple method:

```
$profile = $client->api(
    'ENDPOINT',
    ['parameter name' => 'its value here'],
    'HTTP method like GET for example'
);
```

There are two helper methods:

```
// get method
$client->get('ENDPOINT', ['param' => 'value']);

//post
$client->post('ENDPOINT', ['param' => 'value']);
```

To perform api call to get profile information

```
$profile = $client->get(
    'people/~:(id,email-address,first-name,last-name)'
);
print_r($profile);
```

To list companies where you are an admin

```
$profile = $client->get(
    'companies',
    ['is-company-admin' => true]
);
print_r($profile);
```

To share content on a personal profile

```
$share = $client->post(
    'people/~/shares',
    [
        'comment' => 'Checkout this amazing PHP SDK for LinkedIn!',
        'content' => [
            'title' => 'PHP Client for LinkedIn API',
            'description' => 'OAuth 2 flow, composer Package',
            'submitted-url' => 'https://github.com/zoonman/linkedin-api-php-client',
            'submitted-image-url' => 'https://github.com/fluidicon.png',
        ],
        'visibility' => [
            'code' => 'anyone'
        ]
    ]
);
```
