It helps me test my APIs without writing any code. It also helps me save my APIs, and it allows me to group related APIs together. On top of that, it lets me validate my responses by writing test scripts in JS.

Best thing i like about postman as a developer is it helps a lot to check the current status and response of api's to test and it gives proper response with code which helps a developer to find the route cause if any problem arises, Most of the time, rather than checking the whole code, i check API in postman first to check wheather data is coming or not, if its api fault chhecking code is of no use, postman saves this time. I usually use it more for SMS Service api test, to check the 3rd party api's wheather they are getting proper data or not. at the end Its an very blessing software for developers, dosent depend you are a web dev or an app, same thing works for all.

I find Postman very convenient for API testing. It's easy to create environments and collections, which helps me a lot. I like that Postman automatically creates a request when a curl is provided, and its ability to modify the body and payload is really useful. I can easily understand the existing API structure just by providing the curl and exploring the structure. Setting up Postman was very easy—just install and start using it.
