If you are running Aloaha in non-interactive mode (server or enterprise version required) Aloaha checks a couple of hotfolder for specific tasks. For example it prints every doc/docx dropped into the autoprint folder to Aloaha for PDF conversion.
In the enterprise version you can also utilize the APIs mentioned in:

and

Please note: To switch Aloaha into non interactive mode you need to have admin rights and the correct Aloaha license. Then just right click on the Aloaha system try icon and disable the option “Interactive”
