Here's What Reviewers Working at large Businesses Have to Say About API Security Software

What Enterprise Professionals Liked What Enterprise Professionals Disliked

Postman: “The postman application provides collections, history, creation of api and a runner. This helps in creating mock server, monitoring and documentation.”

Read Review

Postman: “For me, the learning curve. I'm trying to learn to use API with a database and it is just very new to me.”

Read Review

Postman: “Repeatable tests can be run in a sequential order without needing to write a script in a programming language and are easily imported and exported and results are logged for each test run and the resource utilization in the machine is low so several instances can be run in parallel. The collection runner has easily saved me half of my work week for the last 2 years giving me more free time to actually code since the tests are run so easily.”

Read Review

Harness Platform: “There is no support for non-Linux platforms, and build tools are not very customizable. Build configuration is kept separate from your code, which can make things difficult when working in a large team, unless you restrict yourself to a single person with administrative privileges.”

Read Review

Postman: “Most of my job is making sure that valid queries work as expected and invalid ones are rejected and don't break havoc by producing unexpected effects and that the right error messages are displayed so people can correct the query as necessary and that requires a lot of testing and most of it can be done thru postman.”
