The document introduces the WordPress REST API. It discusses what the REST API is, the common REST methods like GET and POST, and how the API provides endpoints to interact with WordPress content remotely via JSON. It then gives an example of how the presenter used the REST API to solve a problem by creating custom routes and callbacks, highlighting tools like JSON Formatter and Postman for testing APIs. The document encourages continuing learning about the REST API on the WordPress developer site.
