// Package api implements REST API for sftpgo.
// REST API allows to manage users and quota and to get real time reports for the active connections
// with possibility of forcibly closing a connection.
// The OpenAPI 3 schema for the exposed API can be found inside the source tree:
// https://github.com/drakkan/sftpgo/tree/master/api/schema/openapi.yaml
