title: Dilemma with TripIt integration
body: <p>We are trying to integrate TripIt with our web application for itinerary management. I created a new App and got api key &amp; secret. But we want to use the employee's trip it account and retrieve their trips &amp; create trip in their account. Now i have one dilemma, since i am using my api key &amp; secret, i can able to retrieve trips created in my account, but i want to retrieve trips of whoever logged in with their tripit account, with my api key.</p>
  
  <p>So in this scenario, i will ask for user's trip it credentials and is there a way i can get their trips using my api key? Any viable solution is welcome. If you clear me with the flow i can able to understand.</p>
