What's the toolset for this Postman software?
could u be more specific? im not sure what u mean. it's easier than curl lol. start with tutorial. it's an easy software to use but requires some intermediate level knowledge about how the internet works. u can do it. if u understand the osi model, u can do it. the 'code' u see on the right of that prior img is a typical json response. its a data encapsulation schema similar to a dictionary. items u see are nested key:value pairs describing nodes in the data and their corresponding variables.
go for it. explore.
