  <p>Hi, I am using <strong>google-api-client</strong> <strong>-v '0.9.8'</strong> newer i am getting issue </p>
  
  <pre><code>client_secrets = Google::APIClient::ClientSecrets.load("/home/secrets.json")
  @auth_client = client_secrets.to_authorization
          @auth_client.update!(
            :scope =&gt; 'https://www.googleapis.com/auth/calendar',
            :access_type =&gt; "offline", #will make refresh_token available
            :approval_prompt =&gt;'force',
            :redirect_uri =&gt; 'http://someurl.com'
          )
   url = @auth_client.authorization_uri 
  link = "https://accounts.google.com/o/oauth2/auth?#{url.query}" 
  </code></pre>
  
  <p>when you click on link a url will it will be redirected to a page where <strong>code</strong> will be genrated </p>
  
  <pre><code>@auth_client.code = "generated code"
  @auth_client.fetch_access_token!
  </code></pre>
  
  <p>To Generate <strong><em>access_token</em></strong> and <strong><em>refresh_token</em></strong></p>
  
  <pre><code>service = Google::Apis::CalendarV3::CalendarService.new
  response = service.list_events('primary',max_results: 10,single_events: true,order_by: 'startTime',time_min: Time.now.iso8601)
  </code></pre>
  
  <p>This point issue will arise</p>
  
  <pre><code>dailyLimitExceededUnreg: Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.
  </code></pre>
  
  <p>FYI
  I enabled google calendar api in google developer console.</p>
  
  <p>If anyone resolved this issue please let me know.</p>
