Elasticsearch 7 and Elastic Stack - In Depth and Hands On! - Introducing HTTP and RESTful APIs

The video tutorial explains RESTful APIs and their application in Elasticsearch. It covers the basics of HTTP requests, including methods like GET, POST, PUT, and DELETE, and their role in communicating with web servers. The tutorial delves into the principles of REST, such as statelessness and client-server architecture, and demonstrates practical examples using curl commands to interact with Elasticsearch. The focus is on understanding how to construct and interpret HTTP requests and responses, applicable across different programming languages.
