The Development Tab in the Account Settings side navigation bar provides your unique user API key. Use your API key to integrate with the Excel add-on or integrated connections that requires an API Key. 

Click the "Generate New Key" button to regenerate your API Key. This will not affect other users, but it will break any connections already established via your API Key. 

The "View API Documentation" button leads the user to the Sensemetrics Documentation webpage, a resource designed to guide users in utilizing API features for development.
