}Authorizations
Organization API token. Generate from Organization Settings → API Tokens.
Body
Optional optimistic concurrency control. Send the updated_at value from the last-fetched exhibitor.
New exhibitor name. When present it must be a non-empty string — an explicit empty string returns 400. Omit the key to leave the name unchanged.
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.
