‣ Separation Between Client and Server
‣ Stateless: No State, You Should Get Same
Data From Same Requests
‣ Cacheable
‣ Layerable: Load-Balancing, etc.
‣ Uniform: REST APIs typically tell you how to
access the data.
‣ Flexible: Doesn’t Matter Where Server/Client
Area, Or What They Are
‣ Simple: Uses Standard/Established Methods

Allows us to build and send
requests to our API and also
process and handle responses. A
really great tool for working with
any type of REST API, not just the
WordPress API.
