Episerver's Marketing Automation Connector for Hubspot


We are currently developing a new website for our organization. Does anyone have any experience with Episerver's CMS and have utilized Episerver's Connect for Marketing Automation for Hubspot Add On to connect their Episerver forms to Hubspot?

I am new to both Episerver/MVC and fairly new to Hubspot. It seems like I am able to get new contact data to come over into Hubspot. However, I need to be able to update existing Hubspot contacts as well. There isn't much documentation from Epi available on this connector (http://webhelp.episerver.com/latest/addons/marketing-automation/hubspot.htm). Does anyone have experience with this connector to get data into Hubspot?
