#1 it is free.
#2 I love the fact that I can test pretty much any API in almost any configuration and get an immediate and correct response.
#3 I can create test payloads with ease and clone/copy my tests into folders for easy sorting and organization
#4 I can send payloads in any format needed (form posts, gets, raw text, json, etc). I can literally recreate any submission type I need.
#5 Once I have the payload sorted out, I can export into any processing format I may need: AJAX/JS, C#, Node/JS, etc.
#5 I can retrieve payload responses and then export those into any format I may need: JSON, XML, plain text, etc.
Believe it or not the biggest issue I have is actually just creating a new "test" inside a Collection. The UI is terrible in that regard. I usually end up duplicating from another collection, sort of blank it out , and then start from there. Maybe I'm not doing something right here but the UI is not clear for me.
I don't know if it is possible but can you make it an option to share or forward an individual test to another user? I see you can export entire Collections but sometimes I don't need quite that much. This would be really nice to have as I work with other developers where I have to export or take screenshots of the tests I'm building local.
Being able to quickly test and debug third-party vendor APIs. This has two benefits 1.) we can hold third-party vendors accountable and immediately put them to work fixing any issues in their services 2.) we can quickly pass payloads of any shape or size to quickly get metrics on the APIs we are testing
