I wanna build sample framework for POC using Rest Assured Java to test REST APIs. Where I can find sample REST APIs for testing purpose.
Related question , although it might be
get only, but it references other stuff which might help, and will also give you an idea of what to Google for.
IGTFY: https://reqres.in/ is what you want.
No more tedious sample data creation, we've got it covered.
Develop with real response codes. GET, POST, PUT & DELETE supported.
24/7 free access in your development phases. Go nuts.
Btw, for testing APIs, be aware of postman
(also, Fiddler2 is helpful, but I dropped it when I moved to Postman; YKMV [Your Kilometrage May Vary]).
