Examples of RESTful API calls for E-commerce platforms

These examples are type 3 RESTful API requests and responses. The JSON-HAL specification is used to implement HATEOAS.

Some of the examples are based on my work as architect of the RESTful API at http://www.hautelook.com. All proprietary information has been removed.
