Add-ons

List add-ons for an event occurrence

Returns organizer-owned add-ons whose current event, occurrence, race, and ticket restrictions apply to this occurrence. An add-on may still apply to only some of the occurrence’s tickets: read its restriction lists (eventIds, eventOccurrenceIds, raceIds, ticketSlugs) — alternative grants combined with OR — and match them against the occurrence’s tickets, joining ticketSlugs on each ticket’s ticketSlug and raceIds on its raceId.

page

PageCursor · object

required

Cursor details for pagination.

In scenarios with large amounts of data, it's common to return only a subset of data in a single request, known as a "page".
Most API responses include two objects: a 'data' object with the query results, and a 'PageCursor' object detailing the current page.
Cursors can be used to navigate to earlier or later pages in the set of results. For instance, passing the 'next' cursor from 'PageCursor' fetches the next set of results.
Cursors are base64 encoded strings.
