REST

Read a REST interface by asking what each resource represents and how clients interact with it. Identify the URI, the representation exchanged, and the information needed to understand an individual request. Keep the external contract focused on what consumers need to accomplish.

The REST architecture guide connects these questions to interface design. Examine collections separately from individual resources, including ordering, navigation, and optional fields. Record how clients learn about related resources and how the service communicates unsuccessful operations.

For a concrete exploration exercise, use GET and PUT with repeatable requests. Compare the intended effect of reading and replacing state, then observe the result in a controlled environment. Preserve the documented assumptions so a future client change or API revision can be checked against the same understanding.
