I have problem using api http://code.google.com/p/simple-linkedinphp/ for posting message in Linkedin groups.
With this request:
$OBJ_linkedin = new LinkedIn($API_CONFIG);
$response = $OBJ_linkedin->createPost( "IDGROUP" , "title test", "message test");
I receive this response:
<error>
<status>403</status>
<timestamp>1369732087697</timestamp>
<request-id>NNPMM1EN5E</request-id>
<error-code>0</error-code>
<message>com.linkedin.anet.auth.pub.ANetAuthException: nonMember: anetID=IDGROUP </message>
<error>
I replace correctly IDGROUP with the group ID and also AppKey and AppSecret are correct.
You have to set the access token
before making the api call.
$OBJ_linkedin->setTokenAccess(array("oauth_token" => $oauth_token,
"oauth_token_secret" => $oauth_token_secret));
