title: How to use single Client ID and API keys For multiple Domains
body: <p>I have main domain ("i.e. <a href="http://www.example.com" rel="nofollow">http://www.example.com</a>") and sub-domain ("i.e.http://*.example.com"). I want to use Google Drive File Picker API, for that I want to use single client ID and API keys for all my sub domain. Conclusion of my research is that, we need to create a separate Client ID and API keys for each sub Domain but, I want to use single Client ID and API Key for all sub-domain. How can I achieve this.</p>
  
  <p>Thank you.</p>
