title: Google app Id find application ID
body: <p>I have a long time application created with GAE api for Python . 
  Unfortunately I have lost the source code and I tried to retrieve it using this command:</p>
  
  <pre><code>appcfg.py download_app -A &lt;app-id&gt; &lt;path&gt;
  </code></pre>
  
  <p>As the app-id I just wrote the first part of the address, for example if I have myApp22.appspot.com - I wrote myApp22. However the script output is "This application does not exist" . I believe it expects a real application ID as explained here: <a href="https://developers.google.com/eclipse/docs/appengine_appid_version" rel="nofollow">https://developers.google.com/eclipse/docs/appengine_appid_version</a><br>
  But I don't have access to my source file. Is there any other way that I can find out my application ID? </p>
  
  <p>Very appreciated.</p>
