Hi, I've developed multiple implementations where php scripts on cron jobs are doing things with NetSuite records outside of NetSuite. I'm curious though if there's anyway to do this more on demand, like have NetSuite call out to the server with the php script on a create or save event. If that's possible is it baked in to NetSuite or would I need to build some API on the server for NetSuite to hook into? Any help is greatly appreciated.
