As far as I know, you cannot use Swagger annotations to send information to users or clients. Swagger annotations are intended only for documentation purposes.

If you need to actually deliver information to users, you should use another solution such as a dedicated web service.

In Swagger, @ApiResponse is used to document the type of your base data transfer objects or to describe specific error responses for particular business cases. If consumers need this information, you can provide it; otherwise, it is not necessary.
