If you run a Facebook Page for your business, you can easily create a 'BOOK NOW' button which links through to your Studio Member Area so that your members can book online, as well as see other services/products you offer.
First, you'll need to know what your unique 'Member Area Name' URL is.
Go to Settings > Member Area > Member Settings > Member Area Website
After you have your link, refer to Facebook's help article on how to create an action button to put the link into so that when a customer clicks it, it leads to the member area!
