I'm using an external service - Unbounce.com - to manage my landing pages. Unbounce gives me the option to post to an external URL using their Webhook Integration.
I'm using Freeform to manage my forms. Can anyone give me some advice on how to hook this up? I suspect it's going to be a URL with "ACT" in it, but I'm not really sure where to start? Do I create a receiver form in Freeform?
