What are companies looking for when they say "knowledge of Restful web services."

[Nathan Milota]

I develop applications using Spring Boot and use the @RestController for the Post, Get, Put, and Delete requests.   Is that what they are asking about, or is there more to it than that?   What would you recommend for someone to meet this criteria?

[Tim Moores]

While practical experience is obviously helpful, the specific framework you used is perhaps less important than understanding the principles of REST.
