REST is the most used mechanism to publish APIs for general consumption. Each language has its own set of libraries and methods that help a developer consume these APIs. This course will teach you how to use Python and its libraries for consuming and creating REST APIs in the easiest way possible.

In the first part of this course, you’ll learn how to work with Python in using REST APIs for various scenarios. Then, in the second part, you’ll focus on building your own REST APIs using the HTTP methods, including GET, PUT, etc.

This course is geared toward intermediate users who have a basic understanding of Python and want to improve their skills in using existing REST APIs and building their REST API implementations.

# Inform clients about supported operations

A client should be able to query a service for the list of supported operations. In the world of REST APIs, that is achieved by issuing an OPTIONS request to the service. Conversely, a REST service uses the OPTIONS method to inform clients about the supported operations. 

#key# According to the specifications:Package org.jboss.netty.handler.codec.http #key#, “The OPTIONS method represents a request for information about the communication options available on the request/response chain identified by the Request-URI.”

According to the above specification, the OPTIONS method has the following features:

* It's idempotent. That means multiple OPTIONS requests to the same URI with the same parameters will result in the same effect on the server as a single OPTIONS request.
* The response should provide all the operations supported by the service as a part of the response header.
* Body is optional for both the request and the response.
* A `200 OK` response will include any optional features implemented by the service.
* Responses are not cacheable.

Similar to GET or DELETE, OPTIONS request has an optional body, and similar to POST, it doesn’t specify a specific resource ID.

Understand the OPTIONS method and design the products API to inform clients about supported operations.
