Hello @Allan Deyoung ,
Thanks for reaching out! Staff members can be part of the Microsoft 365 tenant where the booking business is configured, or they can use email services from other email providers.
To add staff from outside of your organization, use Graph endpoint
POST /solutions/bookingBusinesses/{id}/staffMembers.
And add the following properties in the request Body,
- displayName
- emailAddress
- role
You can refer the below document to create bookingStaffMember from graph API: https://learn.microsoft.com/en-us/graph/api/bookingbusiness-post-staffmembers?view=graph-rest-1.0
Follow steps in the below document to add staff to bookings: https://learn.microsoft.com/en-us/microsoft-365/bookings/add-staff?view=o365-worldwide#steps
Hope this helps.
