title: Does iTunes Connect offer API for managing external testers from tools?
body: <p>iTunes Connect provides a browser-based UI for adding and removing external testers for apps that are in beta test, using Apple's new version of Test Flight.</p>
  
  <p>Is there a way to access this functionality without using the web UI -- for instance, with a command line tool?</p>
  
  <p>It seems like Apple doesn't provide an <em>official</em> API for accessing iTunes Connect programmatically. But a little googling suggests that iTunes Connect is an AngularJS app that talks to a JSON API. Are there any open source projects or working code snippets that show how to use the API?</p>
  
  <p>I am specifically interested in <em>managing external testers</em>, not automating the upload of builds to iTunes Connect.</p>
