title: Cloud Endpoints and App Engine
body: <p>I've just started on Google Cloud and I'm creating an iOS app to interact with Google Cloud services via a mobile backend. I'm using Python to write the backend for App Engine. I've gone through the tutorials in creating an API based on endpoints - but I have a question. </p>
  
  <p>Do I have to create a Cloud Endpoints API, and then an app on App Engine? Basically, I want to be able to register accounts on my iOS app, call an API which then makes use of Google Datastore to store the account details. From looking at the tutorials (both the cloud endpoints one and then the guestbook one), am I meant to expose Google Datastore, cloud storage etc. within the endpoints api? Or does that link into another app where that is all done?</p>
  
  <p>Sorry if this sounds a bit silly, but I just want to make sure!</p>
  
  <p>Thanks in advance.</p>
