Doing this helps clarify the initial questions about interacting with the API quickly before then moving onto implementing a solution with code. There are lots of tools available and of course we would recommend you use whatever you are most familiar with however, the tools we most frequently use are two popular packages

Postman

Postman is an incredibly useful tool which allows you form API calls to services and provides advanced features for managing libraries of saved calls which you can refer back to as you develop your understanding of an API and explore its features.

VSCode & REST Client

REST Client is an extension available within the popular open source developer package VS Code which allows you to construct REST service calls directly within a text editor and execute those calls to get an immediate response. REST Client is very useful for getting that low level view of exactly what data is being exchanged with the API which is sometimes very useful in the early stages of exploring an API. REST Client allows a library of REST Calls to be held as a simple text file and so allows for easy sharing of examples with colleagues.
