Basics

• HTTP requests are built in three parts, the request line, header variables and request body

  

  • VERB: GET, PUT, POST, etc..
  • URI: Uniform Resource Identifier (endpoint)
  • Request Header: metadata about the message
    • Preferred representation formats (e.g., JSON, XML)
  • Request Body: (Optional) Request state
    • Representation (JSON, XML) of resource

• HTTP responses

  

  • Response code: 3 digit HTTP status code (such as 200, 404, etc..)
