Steam API integration

I currently have a script that takes the Steam API and applies that to a field in a Joomla extension called "Easy Social." It was done as a cron job. I was told there is a much better way, if the coder knows Easy Social. Basically, when a user inputs their steam ID and checks the agreement, I need it to place all of their games in a field and their achievements in another area. The field that the games will be put into is an autocomplete field. This field has meta data associated with each game in our database. If our database has the same game title AND the platform of the game is PC (in our database), it needs to use that game. If the title isn't in there or there is the same title but not on the PC platform, it needs to create a new game with platform PC. Apparently, a cron job isn't the best way to do it because it can work instantly with EasySocial.
