YES! MemberVault does have a Zapier app - however, it is an invite-only app which is why you will not find it should you look directly in Zapier's list of apps. 

To access your personalized invitation link, go to your MV Dashboard to Settings > Advanced Integration > Zapier. 

There you will find your unique link to access the app along with your MV account's API details which you'll need to connect MV once in Zapier. 

Note: At this time, our Zapier app is an 'action based' only. This means you can update MemberVault using data from a 'trigger app' but you cannot use MemberVault as a trigger to send data to another app/tool.
