Help with sending data to CRM

Hi all, need some help with getting the info from CF7 and into a CRM via javascript. I’ve read about the DOM events but there isn’t enough info for someone like me to figure it out. The company that hosts the CRM gave me the necessary code but I don’t understand what to do with it. Not to mention the only info on the help section that talks about javascript says that certain things aren’t used anymore. Some guidance would be much appreciated.
