Microsoft Bookings Graph APi Invalid filter clause

Question

I try to filter Microsoft Booking webapi customer endpoint (https://learn.microsoft.com/en-us/graph/api/bookingbusiness-list-customers?view=graph-rest-1.0) using the 1.0 C# Graph SDK based on customer email attribute, but the query always fails with invalid filter clause. This is the filter expression:

var filterexpression = $"emailAddress eq '[email protected]'";

This is the query which using it:

            var customersCollection = await Resilience.Retry(() => _serviceClient.Solutions.BookingBusinesses[bookingbusiness].Customers
                .Request().Filter(filterexpression)
                .GetAsync());

Is filtering supported on bookings api endpoints, and if yes, what is went wrong here?

Answer 1

From the test in Graph Explorer only id property supports filtering.

Other properties like displayName, emailAddress, addresses and phones are not filterable right now.
