Every request that you send in Postman appears under the History tab of the sidebar. On a small scale, reusing requests via the History section is convenient. However, as your Postman usage scales, finding a particular request in your history can become time consuming. This is where Postman Collections come in. Collections are groups of saved requests, and are the cornerstone that most advanced Postman features are built upon.
Let’s pick up where we left off after sending our first request, and create a new collection.
Congratulations! You can see all of your collections under the Collections tab of the sidebar on the left.
