Hi Apoorv,
It looks like you have the Remote Site setup correctly, so you might want to double-check the credentials in Salesforce:
- In Setup > Develop > Custom Settings, select Manage next to
Site Metric Settings and enter your Google Analytics email and password
- To find the Table Id for your site, you can use the Google Analytics Data Feed Query Explorer
To test the credentials, you can make a single call using the Developer Console like this:
- ImportGoogleAnalytics.importSingleMetric(name)
where name is a string with the name of the Custom Settings you created in Setup.
