Body
Required for optimistic concurrency control. Send the updated_at value from the last-fetched session.
Custom field values keyed by field internal name.
For number, currency, and percent fields, an empty
string ("") clears the stored value — identical to
sending null. 0 and "0" store an actual zero.
For checkbox fields, send boolean true or false.
On read, a checked box serializes as the string "Yes", an
explicitly unchecked one as "No", and a box that was never
set as null.
Fields owned by an integration (for example
swoogo_session_id, cvent_session_id,
visit_session_id) are hydrated by the connector and
reject writes with 400 FIELD_READ_ONLY, naming the
field in details.field. Omit them from custom_fields.
Language variants to write using the same shape returned on reads. Omit this key on update to leave existing translations unchanged.

Legacy junction-table speakers (Session_Speakers). Retained for backwards
compatibility. Each entry includes participant_role when the event has
Sessions 2.0 roles configured. Prefer participants for new integrations
that need custom program roles or a single flat participant list.

Flat list of session participants from the Sessions 2.0 data model
(Session_Participants + Session_Roles). Always returned on session
search and get (no expand flag). Includes custom program roles (for example
Author, Panelist) in addition to the legacy speaker/chairperson/moderator
junction tables. Legacy arrays above remain for backwards compatibility;
each legacy entry also includes participant_role when event roles are
configured. Contact profile fields (photo_url, company_name, title,
address_country, etc.) are hydrated from the contact record in the event's
default language without requiring expand.

Subsessions of this parent session. Each item defaults to the
minimal Subsession shape; pass expand=subsession_details to
receive the full SubsessionDetailed shape on every subsession
in the array. Composition fields (is_abstract,
composition_status, optional composition) are inherited from
the parent session.
Items are returned in the order set by the event admin
(subsession_order), falling back to subsession number and then
start time for subsessions that have never been reordered.
A subsession nested within a parent session. This is the default
minimal shape returned inside parent.subsessions[] when the
subsession_details expand value is not requested.
To receive the full parent-shape parity (status, custom_status,
custom_fields, chairpersons, moderators, sponsors,
exhibitors, tags, language, track, level, room, etc.),
pass expand=subsession_details on the GET or POST search request.
See the SubsessionDetailed schema.
is_abstract, composition_status, and optional composition
(when expand=composition) are inherited from the parent session.
Alternatively, call GET /v1/event/{eventId}/sessions/{sessionId}
with the subsession's UUID directly — the endpoint always returns the
full session shape at the top level.
