what cf logs would contain log information about api calls / http calls. I am trying to find out where external and incoming https calls are coming and going through the CF server

calls that coldfusion makes are in the http.log. calls that coldfusion receives I don't think get logged. You would have to add logging to your processing code. The webserver probably logs them -- I know IIS does, but I haven't used any others, so I can't say for sure.

ah ok super many thank @Tim
