Bullhorn REST API: create an Appointment and add Attendees
domain: bullhorn.com · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Authenticate and obtain a BhRestToken as usual.
Create the base Appointment first with a PUT to {corporation-token}/entity/Appointment, without any attendees in the same call.
Take the returned Appointment id and create each attendee separately with PUT {corporation-token}/entity/AppointmentAttendee, one record per call, referencing the parent appointment id.
Repeat the AppointmentAttendee PUT for every invitee (each attendee gets its own Appointment-linked instance).
Query the Appointment along with its attendee association field to confirm all invitees were attached.
Known gotchas
Attendees cannot be embedded in the initial Appointment creation call — Bullhorn requires the two-step create-appointment-then-add-attendees sequence.
Each invited user gets their own Appointment instance; the owner's instance is the parent (parentAppointment is null), and attendee instances reference it.
AppointmentAttendee records must be added one at a time via PUT; there is no documented bulk-attendee endpoint.
