Hi,   So I have spent the majority of my evening trying to get this to work and frustrating my brain.   I have been able to add the webhooks and connections successfully, however when running the connection to see if it will send the contact data over I get "Runtime Error: 400" on Constant Contact's side.   I have tried to do it with the address fields I need to have added and without, and the same for the custom fields, but it still has the same results.   I then thought I would try Zapier, however I haven't been able to see the option to add more fields for it to pass data to (unless I am missing something in the new interface).   Here is a screen shot of the error I get, which doesn't tell me much.     Thanks!   Nakima ...
