modify wordpress scrapping plugin and integrate api with script

Hi It' about to modify plugin that will fetch and scrape data from a site ([login to view URL]), and sync with video php script that I got with api. All process must run in the background so I don't have to wait for the plugin to process before posting the next set of series. Check this video for detail explaination [login to view URL] here're resources including (Plugin, Theme and Video Script) [login to view URL] thanks.
