What is Postman collection?

Postman collection is a group of API requests that can be saved, organized, and shared with others. A collection is a way of grouping related API requests together in one place, making it easier to manage and maintain them. The requests in a collection can be run individually or as a group, and they can be used to test, debug, and document API endpoints. Postman collections provide a convenient way to share and collaborate on API testing and development with others.
