        <item-content>
            <invitation-request>
                <connect-type>friend</connect-type>
            </invitation-request>
        </item-content>
    </mailbox-item>

where %@ indicates dynamic value. Content Type: text/xml Request Method: POST

Response xml :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <error>
        <status>401</status>
        <timestamp>1342092385484</timestamp>
        <request-id>FX9SK3ZVG9</request-id>
        <error-code>0</error-code>
        <message>[unauthorized]. OAU:076lb67kcfe2|dc01dc46-4d78-44d2-9f9b-49053b8094db|*01|*01:1342092534:iZ/mDlOL7eo4fGv2O/rQZKe8oCA=</message>
    </error>

Also verified that authorization header is proper. I have also debugged with oAuth debug console, i have enter same values in debug console, but signature key are different.

So is it a problem with signature key ?? I have also gone through forums. But still i am not able to find an exact problem.

Any help will be appreciated.

Thanks

There's a sample LinkedIn iPhone client on github here: https://github.com/synedra/LinkedIn-OAuth-Sample-Client

You should be able to use that to see what the proper headers look like. As you're on a macintosh (or wouldn't be developing for the iPhone), I strongly encourage you to use HTTPScoop to watch the traffic when using the simulator and see what the differences are between what your application is doing and what the sample client does.
