What is the action performed by @HttpDelete in Salesforce?

The action performed by @HttpDelete in Salesforce is to delete a resource specified in the request. In the context of web services and REST APIs, the HTTP DELETE method is defined to remove a particular resource from the server. When used in Salesforce, this annotation indicates that the associated method is intended to handle incoming HTTP DELETE requests, which are meant to trigger the deletion of records or other entities based on the request.

Understanding RESTful services is crucial here, as different HTTP methods (such as GET, POST, PUT, and DELETE) correspond to different actions on resources. The DELETE method is universally accepted for removing resources, making the association between @HttpDelete and the delete action clear and consistent. This turns it into an essential part of building RESTful services in Salesforce, allowing for effective resource management and manipulation.
