There are two JSON API styles:
The ID style is the easiest to get started with, but requires that your clients be able to guess the URLs for related documents. It also locks your API into a particular URL structure, which may become a problem as your API grows.
The URL style requires less guessing on the client side, and makes clients more resilient to API changes, but is trickier to use with relationships and compound documents.
