I am using an appointment booking app and online booking website provided by Square. On the website, customers can book an appointment by selecting "Any staff" (displayed on the App: "booked with any available") (API returns: any_team_member: true). So on my appointment booking app (Point Of Sale), when I create a new appointment, how can I create an appointment with the description "Any Staff"?
For example: I received a call from my customer, they want to book an appointment at 11:30 on 01/01/2016 with a service, anyone can take care of it. But on the appointment booking app (POS), it is required to select 1 staff (there is no "Any staff" function). This is very confusing and causes many problems with misassignment in our store.
Since this is with the Square Appointments app I’d recommend reaching out to our Customer Success team about this. This Forum is mainly for API, SDK, and developer tool related questions. 
Thanks for your enthusiasm. So what API do I have to use to be able to create a new appointment with the description “any_team_member”:“true”. Thanks!
