Is it possible to implement deletion using the POST method and why?

Yes, deletion can be implemented via the POST method, although there is a specific DELETE method in HTTP.

Reasons for using POST for deletion:

• Client or server limitations that do not support DELETE.
• Security restrictions, for example, firewalls blocking DELETE.
• The need to transmit complex data in the request body.

However, from a REST and HTTP semantics perspective, the DELETE method is more appropriate for deleting resources.

An example of using POST for deletion:

POST /deleteUser
Content-Type: application/json

{"userId":123}

Here, the server will delete the user with id 123 via a POST request.
