What is RESTful API?

• Based on HTTP Protocol
• Resource represent URI(Uniform Resource Identifiers) and should be “Unique”
• Simple URI
• We identify Resource status using HTTP Methods
• Send a data with xml/json

CRUD Action to manage web resource through network.
We have 4 HTTP methods (POST, GET, PUT, DELETE)

• Create (POST)
• Retrieve (GET)
• Update (PUT)
• Delete (DELETE)

API Design

• use a plural noun (e.g, /movies)
• if needed, mention sub-resouce to URL (/movies/23)
• you can also use filter condition (/movies?state=active)

Example

URL	Methods	Description
/Movies	GET	get all movie list
/Movies	POST	add movie
/movies/:title	get	get title of the movie
/movies/:title	DELETE	delete title of the moive
/movies/:title	PUT	update title of the movie
/movies?min=9	GET	Movie list which is currently running
