Active ones only unless `include_archived=true`. `sold` counts seats on placed orders; `available` is `capacity - sold` (never below 0), or `null` when the ticket type has no capacity. Not paginated. Requires `read:registrations` (legacy tokens with no scopes pass). ## OpenAPI ````yaml /api-reference/openapi.yaml get /v1/event/{eventId}/ticket-types openapi: 3.1.0 info: title: Sessionboard Public API version: '1.0' description: >- REST API for managing sessions, speakers, contacts, sponsors, exhibitors, and event data on the Sessionboard platform. contact: name: Sessionboard Support email: support@sessionboard.com termsOfService: https://www.sessionboard.com/legal/terms-of-service servers: - url: https://public-api.sessionboard.com description: US Region - url: https://public-api-eu.sessionboard.com description: EU Region security: - ApiKey: [] - BearerToken: [] tags: - name: Events description: Manage events on the platform. - name: Sessions description: Search and retrieve sessions within an event. - name: Session Writes description: >- Create, update, delete, and restore sessions.
