- GET to retrieve data
- POST to create a new data entry
- PUT to update an existing data entry
- DELETE to remove a data entry

RESTful APIs should conform to a uniform interface, meaning that all resources are uniquely identifiable through a single URL and that the standard methods are used to manipulate these resources.
RESTful APIs must also conform to a stateless, client-server-based structure. This means that there is a clear separation between the Server, which contains the data, and the Client, which can contain the UI that an end-user will use. Stateless means that each request has a defined purpose and that nothing is saved between requests that could change the output.
