Restore a deleted exhibitor

POST/v1/event/{eventId}/exhibitors/{exhibitorId}/restore

US Region: https://public-api.sessionboard.com · EU Region: https://public-api-eu.sessionboard.com

Restore a previously soft-deleted exhibitor. Requires the write:exhibitors scope.

Restore has the same reach as the delete it reverses: it restores the group, so a group that held both roles comes back as both a sponsor and an exhibitor, and it reappears on every event it was linked to — not only the event in the path.

Request example

curl --request POST \
  --url 'https://public-api.sessionboard.com/v1/event/{eventId}/exhibitors/{exhibitorId}/restore' \
  --header 'x-access-token: <api-token>'

const response = await fetch('https://public-api.sessionboard.com/v1/event/{eventId}/exhibitors/{exhibitorId}/restore', {
  method: 'POST',
  headers: {
    "x-access-token": "<api-token>"
  },
});

const data = await response.json();
console.log(data);

  The formatted field value, or null when the field is empty. Numeric field types (number, currency, percent, quantity, formula) serialize a stored zero as its formatted value (for example "0") — null means the field has no value, not that the value is zero.
  
  checkbox fields serialize as the strings "Yes" (checked) and "No" (explicitly unchecked); a checkbox that was never set is null. Writes take boolean true / false.
  
  datetime fields serialize as ISO 8601. On event custom fields (GET /v1/events?expand=custom_fields) the value is event-local time with the event's UTC offset (for example 2026-08-15T09:00:00-03:00), falling back to the raw UTC instant (2026-08-15T12:00:00.000Z) when the event has no valid timezone. On session, speaker, sponsor, and exhibitor custom fields the value is the raw UTC instant.
  
  date (date-only) fields serialize as M-DD-YYYY: month without a leading zero, day with one, four-digit year (for example 9-22-2026 for 22 September 2026, 3-04-2026 for 4 March 2026). This is not ISO 8601; parse it with that exact pattern.

400

The exhibitor is not deleted, so there is nothing to restore. Restore is not idempotent — check before retrying.

401

Unauthorized

403

Missing write:exhibitors scope

404

No exhibitor with this id on this event. A record that exists but does not hold the exhibitor role — a contact, or a group linked only as the other role — is also a 404 here; look it up on the endpoint for the role it holds.
