Swagger UI

From a StackShare Community member: "I just started working for a start-up and we are in desperate need of better documentation for our API. Currently our API docs is in a README.md file. We are evaluating Postman and Swagger UI. Since there are many options and I was wondering what other StackSharers would recommend?"

I use Postman because of the ease of team-management, using workspaces and teams, runner, collections, environment variables, test-scripts (post execution), variable management (pre and post execution), folders (inside collections, for better management of APIs), newman, easy-ci-integration (and probably a few more things that I am not able to recall right now).

I use Swagger UI because it's an easy tool for end-consumers to visualize and test our APIs. It focuses on that ! And it's directly embedded and delivered with the APIs. Postman's built-in tools aren't bad, but their main focus isn't the documentation and also, they are hosted outside the project.

I recommend Postman because it's easy to use with history option. Also, it has very great features like runner, collections, test scripts runners, defining environment variables and simple exporting and importing data.

Decisions about Fiddler and Postman

Postman supports automation and organization in a way that Insomnia just doesn't. Admittedly, Insomnia makes it slightly easy to query the data that you get back (in a very MongoDB-esque query language) but Postman sets you up to develop the code that you would use in development/testing right in the editor.

        Review of
        Postman

        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.

        Review of
        Postman

        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.

        How developers use Fiddler and Postman

        Postman

        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

        Rashid Muhammad uses
        Postman

        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.

        Xpertz uses
        Postman

        Used to test API endpoints and monitor API which also acts as an API heartbeat to keep functions alive in Google Cloud in order to avoid timeout responses to Slack.

        David Flynn uses
        Postman

        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.
