A microsite name is a globally unique way of referencing a restaurant via the ResDiary API. The microsite name for a restaurant is typically just the restaurant's name, with any spaces and special characters removed.
You can find out the microsite name of a particular restaurant via Settings -> Venue -> Venue and Microsite Details in the diary application, and you can get a list of the microsite names for the restaurants that your API account has access to by making a call to list accessible restaurants.
