Hi,

I am in the last step of Salesforce Integration with Linked in. I got oauth_token and oauth_token_secret in my response .

Now i have to use it and make the API call to get the data.

I am trying it with the following code

        final String TripItAccessDataUri='https://api.linkedin.com/v1/people/~/format/json';

         Http h = new Http();
        HttpRequest req = new HttpRequest();
        req.setMethod('GET');
        req.setEndpoint(TripItAccessDataUri);

     final String oAUth_BASE_signature =   

 SignatureBaseStringForAccessData(TripItAccessDataUri,unAuthorisedToken,unAuthorisedKey,nonceValue,timeStamp ,oauth_token_secret);

String signature = SignatureForAccessData(oAUth_BASE_signature ,consumerKey_Secret+'&'+unAuthorisedKey);

req.setHeader('Authorization','OAuth realm=\"https://api.linkedin.com/\",oauth_nonce=\"'+nonceValue+'\",oauth_signature_method=\"'+oauth_signature_method+'\",oauth_timestamp=\"'+timeStamp+'\",oauth_consumer_key=\"'+oauth_consumer_key+'\",oauth_token=\"'+oauth_token_secret+'\",oauth_signature=\"'+signature+'\",oauth_version=\"'+oauth_version+'\"');

reqstr ='Signature' + signature +'###OAuth realm=\"https://api.linkedin.com/\",oauth_nonce=\"'+nonceValue+'\",oauth_signature_method=\"'+oauth_signature_method+'\",oauth_timestamp=\"'+timeStamp+'\",oauth_consumer_key=\"'+oauth_consumer_key+'\",oauth_token=\"'+oauth_token_secret+'\",oauth_signature=\"'+signature+'\",oauth_version=\"'+oauth_version+'\"';

HttpResponse res = h.send(req);

resData =  res.getBody();

public String SignatureBaseStringForAccessData(String TripItAccessDataUri,String unAuthorisedToken,String unAuthorisedKey,String  nonceValue ,Long timeStamp, String oauth_token_secret) {
        String httpmethod = 'GET';

       String oAUTH_PARA='oauth_consumer_key='+oauth_consumer_key+'&oauth_nonce='+nonceValue +'&oauth_signature_method='+oauth_signature_method+'&oauth_timestamp='+timeStamp+'&oauth_token='+oauth_token_secret+'&oauth_version='+oauth_version+'';
        String BASE_STRING = httpmethod+'&'+EncodingUtil.urlEncode(TripItAccessDataUri,'UTF-8')+'&'+EncodingUtil.urlEncode(oAUTH_PARA,'UTF-8');
        return BASE_STRING;
    }

public String SignatureForAccessData(String Signature_Base_Value,String Key){
          Blob mac = Crypto.generateMac('HmacSHA1',Blob.valueOf(Signature_Base_Value),Blob.valueOf(Key));
          String macUrl = EncodingUtil.urlEncode(EncodingUtil.base64Encode(mac),'UTF-8');
          return macUrl;

    }

Please have a look at it for 5 mins . any suggestion would be helpful . This is really urgent

Thanks in advance!!
