I use Postman pretty much every day, and the features I rely on the most are Environments and Variables. Being able to switch between development, staging, and production without editing every single request saves me from making a lot of silly mistakes, especially when I'm juggling multiple projects at the same time. I've also really liked how the API Collaboration features have evolved. Sharing collections, documentation, examples, and test cases with the rest of the team has replaced a bunch of separate documents we used to maintain. Everything lives in one place now, which makes life a lot easier. On top of that, the documentation around Postman itself is some of the best I've worked with. Performance has been solid too. Even with fairly large collections, I rarely run into stability issues.

I like using Postman for API development and loading data because it makes it easier to validate API functionality. I find it helpful that Postman provides a straightforward way to create and execute API requests while giving clear visibility into request headers. Features like Collections, environments, and Automated test scripts save time, reduce human error, improve test consistency, and make it easier to troubleshoot issues. The initial setup of Postman was easy, requiring not much effort and feeling very constructive.

Postman is one of the best API testing tool. The storage structure is very simple
