title: What is the redirectURL I should put in my Uber app?
body: <p>I'm reading Uber's sdk/api doc but I am a rookie and I don't know what the redirectURL should be. Is it a given url from Uber? Because I couldn't find it. Or is it an url for a webpage customized by app developer deployed their own server/local machine? If so, how should I write it?</p>
  
  <p>Totally confused on this point.</p>
  
  <p>Please help with some details as possible.</p>
  
  <p>Many thanks!</p>
