We all know that moment when you are running a Salesforce project for a couple of months (or even years), and we need to do a configuration review. Which field is not used anywhere, which permission set is assigned to which user, do we have duplicates in our custom labels… Tricky right? What if you had the opportunity to retrieve all these info with just a query. That’s what you will learn to do with the Tooling API. And be sure, Admins will use it even more than developers.
