Error pulling companies user is admin of in LinkedIn - rest

Question

I'm currently trying to pull the list of company pages a user is the admin of with the LinkedIn API and am getting the following response:
Array
(
[response] => {
"errorCode": 0,
"message": "Member does not have permission to get companies as admin.",
"requestId": "R1LHP32UKD",
"status": 403,
"timestamp": 1482357250945
}
[http_code] => 403
)
The call works perfectly when authenticated as the same user in the LinkedIn API Console.
Has anyone else come across this?

Answer 1

I figured out the problem.
Even though I had made sure the app had the rw_company_admin permission checked off, I wasn't passing that in the scope when requesting oath2 authorization.
My fixed code below:
The call:
return $linkedin->getAuthorizationUrl("r_basicprofile w_share rw_company_admin", $thisurl);
The function:
public function getAuthorizationUrl($scope, $callback)
{
$params = array('response_type' => 'code',
'client_id' => $this->api_key,
'scope' => $scope,
'state' => uniqid('', true), // unique long string
'redirect_uri' => $callback,
);
// Authentication request
$url = 'https://www.linkedin.com/uas/oauth2/authorization?' . http_build_query($params);
// Needed to identify request when it returns to us
$_SESSION['Linkedin_state'] = $params['state'];
$_SESSION['Linkedin_callback'] = $callback;
// this is where to send the user
return $url;
}

First you have to get user token of linkedin user
Use Socialite or REST API package for oauth.
Once you having user token it is pretty simple to fetch Company list under admin user
$token = 'uflefjefheilhfbwrfliehbwfeklfw'; // user token
$api_url = "https://api.linkedin.com/v1/companies?oauth2_access_token=".$token."&format=json&is-company-admin=true";
$pages = json_decode(file_get_contents($api_url));
You have get $pages json array of list of company profile.
