LinkedIn API Client with OAuth 2 authorization written on PHP
============================================================
[](https://travis-ci.org/zoonman/linkedin-api-php-client) [](https://codeclimate.com/github/zoonman/linkedin-api-php-client) [](https://packagist.org/packages/zoonman/linkedin-api-php-client) [](https://github.com/zoonman/linkedin-api-php-client/blob/master/LICENSE.md)
See [complete example](examples/) inside [index.php](examples/index.php) to get started.
## Installation
You will need at least PHP 7.3. We match [officially supported](https://www.php.net/supported-versions.php) versions of PHP.
Use [composer](https://getcomposer.org/) package manager to install the lastest version of the package:
```bash
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.
## Get Started
Before you will get started, play visit to [LinkedIn API Documentation](https://docs.microsoft.com/en-us/linkedin/).
This will save you a lot of time and prevent some silly questions.
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.
Save ClientId and ClientSecret, you will use them later.
#### Bootstrapping autoloader and instantiating a client
```php
// ... 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(
'YOUR_LINKEDIN_APP_CLIENT_ID',
'YOUR_LINKEDIN_APP_CLIENT_SECRET'
);
```
#### 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:
```php
$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
Set a custom redirect url use:
```php
$client->setRedirectUrl('http://your.domain.tld/path/to/script/');
```
#### 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:
```php
use LinkedIn\Scope;
// define scope
$scopes = [
Scope::READ_LITE_PROFILE,
Scope::READ_EMAIL_ADDRESS,
Scope::SHARE_AS_USER,
Scope::SHARE_AS_ORGANIZATION,
];
$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
To get access token use (don't forget to set redirect url)
```php
$accessToken = $client->getAccessToken($_GET['code']);
```
This method returns object of `LinkedIn\AccessToken` class.
You can store this token in the file like this:
```php
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
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.
```php
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['expiresAt']);
// set token for client
$client->setAccessToken($accessToken);
```
#### Performing API calls
All API calls can be called through simple method:
```php
$profile = $client->api(
'ENDPOINT',
['parameter name' => 'its value here'],
'HTTP method like GET for example'
);
```
There are 3 helper methods:
```php
// get method
$client->get('ENDPOINT', ['param' => 'value']);
//post
$client->post('ENDPOINT', ['param' => 'value']);
// delete
$client->delete('ENDPOINT');
```
#### Examples
##### Perform api call to get profile information
```php
$profile = $client->get(
'me',
['fields' => 'id,firstName,lastName']
);
print_r($profile);
```
##### List companies where you are an admin
```php
$profile = $client->get(
'organizations',
['is-company-admin' => true]
);
print_r($profile);
```
##### Share content on a personal profile
Make sure that image URL is available from the Internet (don't use localhost in the image url).
```php
$share = $client->post(
'ugcPosts',
[
'author' => 'urn:li:person:' . $profile['id'],
'lifecycleState' => 'PUBLISHED',
'specificContent' => [
'com.linkedin.ugc.ShareContent' => [
'shareCommentary' => [
'text' => 'Checkout this amazing PHP SDK for LinkedIn!'
],
'shareMediaCategory' => 'ARTICLE',
'media' => [
[
'status' => 'READY',
'description' => [
'text' => 'OAuth 2 flow, composer Package.'
],
'originalUrl' => 'https://github.com/zoonman/linkedin-api-php-client',
'title' => [
'text' => 'PHP Client for LinkedIn API'
]
]
]
]
],
'visibility' => [
'com.linkedin.ugc.MemberNetworkVisibility' => 'CONNECTIONS'
]
]
);
print_r($share);
```
##### Get Company page profile
```php
$companyId = '123'; // use id of the company where you are an admin
$companyInfo = $client->get('organizations/' . $companyId);
print_r($companyInfo);
```
##### Share content on a LinkedIn business page
```php
// set sandboxed company page to work with
// you can check updates at
// https://www.linkedin.com/company/devtestco
$companyId = '2414183';
$share = $client->post(
'ugcPosts',
[
'author' => 'urn:li:organization:' . $companyId,
'lifecycleState' => 'PUBLISHED',
'specificContent' => [
'com.linkedin.ugc.ShareContent' => [
'shareCommentary' => [
'text' => 'Checkout this amazing PHP SDK for LinkedIn!'
],
'shareMediaCategory' => 'ARTICLE',
'media' => [
[
'status' => 'READY',
'description' => [
'text' => 'OAuth 2 flow, composer Package.'
],
'originalUrl' => 'https://github.com/zoonman/linkedin-api-php-client',
'title' => [
'text' => 'PHP Client for LinkedIn API'
]
]
]
]
],
'visibility' => [
'com.linkedin.ugc.MemberNetworkVisibility' => 'PUBLIC'
]
]
);
print_r($share);
```
##### Setup custom API request headers
Change different headers sent to LinkedIn API.
```php
$client->setApiHeaders([
'Content-Type' => 'application/json',
'x-li-format' => 'json',
'X-Restli-Protocol-Version' => '2.0.0', // use protocol v2
'x-li-src' => 'msdk' // set a src header to "msdk" to mimic a mobile SDK
]);
```
##### Change default API root
Some private API access there.
```php
$client->setApiRoot('https://api.linkedin.com/v2/');
```
##### ~Image Upload~
I assume you have to be LinkedIn partner or something like that.
Try to upload image to LinkedIn. See [Rich Media Shares](https://docs.microsoft.com/en-us/linkedin/marketing/integrations/community-management/shares/rich-media-shares)
(returns "Not enough permissions to access media resource" for me).
```php
$filename = '/path/to/image.jpg';
$client->setApiRoot('https://api.linkedin.com/');
$mp = $client->upload($filename);
```
