The ‘q’ parameter enables clients to express their preferences when multiple resource representations are available. The ‘q’ parameter value ranges from 0 to 1, with 1 indicating the highest preference and 0 the lowest.
In case of web APIs, N+1 problem is a situation where client applications are required to call the server N+1 times to fetch 1 collection resource + N client resources, mostly because of collection resource not had enough information about child resources to build it’s user interface complete.
Use PUT when modifying a resource that is already a part of resource collection. Use POST when adding a child resource to the collection.
