Have you worked with collections in Postman for organizing requests?

Postman collections are used to group and organize related API requests. This is convenient for structuring tests, reusing requests, and collaborating within a team. A collection can store requests with their parameters, pre- and post-request scripts, as well as environment variables.

Example of use: create a collection for testing REST API, add requests for authentication, data retrieval, updating, and deletion. By running the collection through the Collection Runner, you can automate the sequential execution of requests with checks.
