Referenced entities may be embedded multiple times. With the five HTTP methods GET, POST, PUT, PATCH and DELETE you can provide CRUD functionality (Create, Read, Update, Delete) and beyond.

Representational State Transfer (REST) in simple words, is a software architectural style that defines the criteria for creating Web Services where state of Web Resources is modified by the requesting system using consistent and pre-defined set of stateless operations. of our readers. So the client only has to check if the cancelation links are present (for example to know if he should draw the cancelation button). Finally, in practice, and particularly for us at Palantir, CRUD omits two other operations that are vitally important to any initial REST API design: Search and Security-Change/Hard Delete. So we moved domain knowledge away from the client back to the server. In order to change an existing field (rename or change structure), you can add the new one next to the old field and deprecated the old one in the documentation. After a while, you can remove the old field. Also, we're talking about a resource that is subordinate to /subscriptions/{subscriptionid} , so convention (see RFC 3986) calls for expressing that relationship with a path segment, rather than using the query part.

Keep your URLs simple and the URL set small. The six principles of REST architecture are discussed. Choose one base URL for your resource and stick to it. Designing the API first before starting the development gives us a lot of advantages.

This solves already many of the disadvantages of offset-based pagination, but its still not perfect and not very convenient for the client. Thats why its better to use an indexed column. Due to its simplicity, URL versioning is very popular and widely used by companies like Facebook, Twitter, Google/YouTube, Bing, Dropbox, Tumblr, and Disqus.
