        If you're building an API service, this Chrome extension is a must-have. It'll let you ping your endpoints using a nice clean UI that's built right into Chrome. You can also share your previous requests - a simple way to 'document' your API if you're short on time.

        If someone is having trouble shipping data to the Knowtify API, I almost always share my postman collection. Working through the issue from there is typically pretty easy.

        Not much to say, it's the best free tool out there for testing APIs. Get it.

        Postman is a powerful tool for performing integration testing with your API. It allows for repeatable, reliable tests that can be automated and used in a variety of environments and includes useful tools for persisting data and simulating how a user might actually be interacting with the system

        We use Postman in conjunction with our universal REST-API "JCVortex". Postman makes testing edge-cases hassle-free and lets testing look easy. Postman was also a great help to explore the Mojang-API, that we are dependent on, because it is the central repository for minecraft-account-data.

        I use it for testing my Web Api. It's a easy tool for interacting with a RESTFul API and provides great tools for organizing requests. The Newman tool is great for allowing your tests to run in a CI/CD pipeline.

        We use Postman for all our API testing. Postman is invaluable. We would like to have a team licence so that we can use shared work spaces and test collections.
