    update:
      x-apievangelist-gaps:
        - No idempotency key on the single write operation.
        - No pagination on either collection endpoint.
        - Rate limits published in prose only; no 429 and no RateLimit-* headers documented.
        - No stable machine-readable error codes; errors are human-readable strings.
        - No first-party webhooks; events are delivered through Zapier only.
  - target: $.paths['/event/register'].put
    update:
      x-apievangelist-consequence: contacts-a-third-party
      x-apievangelist-idempotency: none
      x-apievangelist-note: >-
        The only write operation. Creates a registrant and may send a Demio confirmation
        email to a real person. Demio does not document replay behaviour and accepts no
        client-supplied idempotency key, so a retry can duplicate both the registrant and
        the email. The returned `hash` is the only handle on the registrant and is
        returned once — persist it or the join link is unrecoverable.
  - target: $.paths['/report/{date_id}/participants'].get
    update:
      x-apievangelist-pii: true
      x-apievangelist-note: >-
        Returns registrant names, email addresses and registration form-field values for
        an entire Session, unpaginated and with no published ceiling on response size.
  - target: $.paths['/ping/query'].get
    update:
      x-apievangelist-warning: >-
        Places the account API secret in the query string, where it is captured by proxy
        logs, server access logs and browser history. Prefer the Api-Key/Api-Secret header
        form on GET /ping.
  - target: $.paths['/events'].get
    update:
      x-apievangelist-pagination: none
      x-apievangelist-note: >-
        Returns every active Event in one response. No limit/offset/cursor parameter and no
        total count, against a 5,000 call/day account quota.
