I have gotten a basic Zapier integration going. At the moment it can create a lead and also be triggered when a lead is created (customise it with the filters).
If you want to have a go use the following link to get access to the app https://zapier.com/developer/invite/19297/1d042feafbdb968c7aae97431b908f7c/
Development wise/requested features where is the best spot for people to request added features (Github doesn't feel like the right spot).
Let me know how it goes, the app explains what you need to do to get it setup. Basically turn on Oauth V2 in the site settings and generate some API credentials for Zapier using the given callback URI.
There is a new version of the integration that works for 2.3. This is a new integration as there has been a significant change to how the authentication works.

I will update “Getting Mautic co-operating with Zapier” https://medium.com/@zpetterd/getting-mautic-cooperating-with-zapier-3267bd2e72ea shortly
This does require version 2.3 of Mautic to work
