PHP OAuth class Post to user's LinkedIn Account

In the end it says it is redirecting to LinkedIn site. Did it redirect?

It also says "Resetting the access token status". Are you calling ResetAccessToken function anywhere in your script? You shouldn't because this makes the class "forget the tokens and any other information about the authorization process.

Manuel,

First: Happy New Year! And thank you for your support.

I have commented the code that resets the status. Here is my code:

Once again: I'm trying to publish company share on behalf of my company. I am administrator of this company.

============================
$api_url = "http://api.linkedin.com/v1/companies/{id-of-my-company}/shares";

$parameters = new stdClass();
$parameters->comment = 'Some comment';
$parameters->content = new stdClass();
$parameters->content->title = 'Some title';
$parameters->content->description = 'Some description';
$parameters->content->{'submitted-url'} = 'http...';
$parameters->visibility = new stdClass();
$parameters->visibility->code = 'anyone';

$client = new oauth_client_class;
$client->debug = 1;
$client->debug_http = 1;
$client->server = 'LinkedIn';
$client->client_id = 'xxxxxxxxxxxxxxx'; // Taken from my profile
$client->client_secret = 'yyyyyyyyyyyyyyyyy'; // Taken from my profile
$client->scope = 'rw_nus';

if (($success = $client->Initialize())) {
if (($success = $client->Process())) {
if (strlen($client->access_token)) {
$success = $client->CallAPI(
$api_url, 'POST', $parameters, array(
'FailOnAccessError' => true,
'RequestContentType' => 'application/json'
)
);
}
}
$success = $client->Finalize($success);
}

if ($success) {
// ...
} else {
echo $client->error . "\n"
}
==============================

Here is the log:

It does not publish to LinkedIn. What could be wrong?

Thank you for your support.

As you may see in the last line, it says it is redirecting to LinkedIn, so the user gives your application permission to access to LinkedIn API on his behalf.

Does the browser redirect to LinkedIn permission page? If not, your script is doing something to prevent the redirection of the browser.

Manuel, I am trying to create a new post to LinkedIn on behalf of my company (post with a company logo on the left, title, short description and link to our website to the whole story). I don't want to redirect the user. The user just pushes a button (on our website CMS)and this action should post some data to LinkedIn and create an update there. No redirects at all.

Yes, but first the user needs to give permission for your application to do that.

The way the OAuth protocol works, is that you need to redirect the user to a specific page of LinkedIn with certain parameters. The user is informed about the permissions you need and if he agrees, LinkedIn redirects the user back to your site passing some tokens for your site to complete the protocol steps.

The OAuth client class simplifies the passing of information back and forth LinkedIn, but the redirection to the authorization page is mandatory. You cannot do anything with the user permission.

In your case the user is your company profile administrator, but the authorization step still must happen.

So you need to make sure the redirect happens at least once.

If the token expires or is revoked for some other reason, you need to repeat the process.

Read this article to understand better the details:

phpclasses.org/blog/package/7700/po ...

OK, I read the article and as long as I understand all the steps were passed in my script. I authenticate with all the permissions and pass the variables (title, description..). It does not return an error but does not publish the update as well. What may I miss? Does the API expect additional calls? It looks like the API expects something more?

If you proceeded past the redirect, you need to post the new log again, so I can advise.

You may as well check the authentication_error and access_error variables.

Hey Manuel,

Is there any sample code in php for posting sharing in linkedin?
Here , what is the $user and $client and can you give callApi() method.?

Thanks in advance,

Just use the API URLs of the LinkedIn API documentation you want to call.
