It has the same function as the API, only for the SSL API it is more secure because it is equipped with an ssl certificate. This SSL API runs on port 8729. you can change the port or disable it when not in use.
# API-SSL Port Enable
/ip service set api-ssl port=8729 address=0.0.0.0/0 disabled=no
# API-SSL Port Disable
/ip service set api-ssl port=8729 address=0.0.0.0/0 disabled=yes
