A web API handles requests and sends responses using HTTP protocol across the internet. A web API has a load balancer to allocate requests to servers running the application to prevent server overload. It has a router to direct each request to the appropriate resource on the server to handle it. It has views that handle requests, make queries to a database, and return responses typically formatted as JSON or XML.
