title: How to get an access token for a simple Dropbox app?
body: <p>My client has a Dropbox folder with files they want to make available on their web site in a custom widget we're building. I understand how to use the Dropbox API v2 to get the list, but where does the OAuth access token come from?</p>
  
  <ul>
  <li>Do I need to create a formal Dropbox app just to do this?</li>
  <li>Does my client need to create an app since it's their Dropbox folder?</li>
  <li>Is an "app" even necessary? I'm hoping it's not.</li>
  </ul>
  
  <p>(The access token is protected behind an AWS Lambda function, in case you're wondering.)</p>
