Restful API Guidelines - A model set of guidelines for RESTful APIs, created by Zalando

Great RESTful APIs look like they were designed by a single team. This promotes API adoption, reduces friction, and enables clients to use them properly. To build APIs that meet this standard, and to answer many common questions encountered along the way of RESTful API development, the Zalando Tech team has created this comprehensive set of guidelines. We have shared it with you to inspire additional discussion and refinement within and among your teams, and contribute our learnings and suggestions to the tech community at large.
