title: ASP.NET WebForms - Calling Multiple API's and show result to user
body: <p>I am working on creating a Web site like www.hipmunk.com in ASP.NET web forms.
  I need to pull the data from multiple API's and compare the rates and show the different rate options to the users.
  What is the best way to achive this? 
  I am browsing around and see "Windows Workflow Foundation" may be an option. </p>
  
  <p>Anyone got suggestions for me? I am just looking for architectural suggestions.</p>
  
  <p>Thanks</p>
  
  <p>EDIT: Multiple API: - Each OTA's have different type of API's but so far I have seen everyone supports the XML/JSON format</p>
