According to REST principles, which is the recommended way to update the order resource identified by 1234?

Question

Options

• ASend a PUT request to /orders/edit?id=1234.
• BSend a PUT request to /orders/1234.
• CSend a POST request to /orders/1234.
• DSend a POST request to /orders/edit?id=1234.

• B
  96% (23)
• C
  4% (1)

Explanation

B is correct because REST uses resource-based URLs where the identifier is part of the path (/orders/1234), and PUT is the idiomatic HTTP method for replacing/updating an existing resource at a known URI.

Why the others are wrong:

• A (/orders/edit?id=1234) violates REST by encoding the action ("edit") in the URL and hiding the identifier in a query string - REST URLs should identify resources, not actions.
• C (POST /orders/1234) uses the wrong method; POST is for creating new resources or submitting data to a processor, not updating a specific known resource.
• D (POST /orders/edit?id=1234) commits both mistakes: wrong method (POST) and action-based URL with a query string identifier.

Memory tip: Think of REST URLs as nouns (resources), not verbs (actions) - /orders/1234 names a thing, while /orders/edit names an action. Then map the verb to the HTTP method: PUT = Update/Replace.
