Postman is the tool most people use constantly and never actually learn properly, pasting URLs into a blank request, hardcoding a token directly into a header, clicking Send and eyeballing the response. This post covers it the way it's actually meant to be used, with the Product API from the earlier CRUD and Swagger posts as the working example throughout.
Collections and Requests
A Collection is a named folder of related requests, keeping every endpoint for one API grouped together, instead of a scattered pile of unsaved tabs that disappear when Postman restarts.
Think of a filing cabinet drawer labeled "Products API," with individual folders inside for each request type, versus loose papers scattered across a desk. Nothing is lost, nothing has to be rebuilt from memory the next time you need it.
