show_as_token_endpoint_url = true
service_url = "https://localhost:${mgt.transport.https.port}/services/"
username= "${admin.username}"
password= "${admin.password}"
ws_endpoint = "ws://localhost:9099"
wss_endpoint = "wss://localhost:8099"
#http_endpoint = "http://localhost:${http.nio.port}"
https_endpoint = "https://localhost:${https.nio.port}"
  2. Comment the HTTP GW endpoint of deployment.toml file and save it
  3. Start the server
  4. Create an API and publish it
