title: Google Analytics API authorization for CMS (Single authorization)
body: <p>I'm developing a 'CMS' for use in clients websites and I would like to include a few analytics views. I have searched and I found some things like this one in google analytics demos and tools (<a href="https://ga-dev-tools.appspot.com/embed-api/third-party-visualizations/" rel="nofollow noreferrer">https://ga-dev-tools.appspot.com/embed-api/third-party-visualizations/</a>), but it needs you to be logged with the analytics google account to show them.</p>
  
  <p>I have seen Worpdress plugins that shows analytics in the dashboard and you only have to authorize them once and not to be logged in google. ¿How is this done?</p>
  
  <p>I need to show client analytics in the dashboard of the CMS, but I don't want to ask for login everytime or request to be logged in their google accounts.</p>
  
  <p>Thanks to anyone who can help.</p>
