Zapier integration?

I am using Zapier for event integration with Meetup.com (and other social media sites).

What I want to do is be able to create an event in WordPress, and then Zapier picks iy up and publishes it elsewhere.

However, when I create the event in Events Manager, and then log into Zapier, Zapier cannot see the Date fields for the event. I can see other fields (like Title).

Thanks.
