//Pass in the endpoint to be used
 public String responseBody{get;set;}
 public String authCode{get;set;}
 public String authorizationCodeURI{get;set;}
 public String body{get;set;}
 
public LinkedInIntegrationController(){
 
 authCode = ApexPages.currentPage().getParameters().get('code');
 authorizationCodeURI = 'https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=vcsdjaaa2ell31l& state=DCEEFWF45453sdffef424&redirect_uri=https://c.ap1.visual.force.com/apex/LinkedInPage';
 HttpResponse resToken;
 if(authCode != NULL){
 
//POST Request by using the authorization code
 Http hToken = new Http();

JSONWrapper jsonWrapObj = (JSONWrapper)JSON.deserialize(body, JSONWrapper.class);
 
//GET Request by using the access token
 Http h=new Http();
 HttpRequest req = new HttpRequest();
 req.setEndpoint('https://api.linkedin.com/v1/people/~/email-address?oauth2_access_token='+jsonWrapObj.access_token);
