      intent: Record event attendance state by contact email
      effect: write
      questions:
      - How do I mark a list of contacts as registered or attended for a marketing event using their email addresses?
      - Will recording a subscriber state by email create the contact if it doesn't exist?
      instructions:
      - text: Set contacts {inputs} to {subscriberState} for event {externalEventId} in account {externalAccountId}, matching by email.
        slots:
          inputs: requestBody.inputs
          subscriberState: path.subscriberState
          externalEventId: path.externalEventId

      intent: Record event attendance state by contact ID
      effect: write
      questions:
      - Can I record that contacts cancelled or attended an event when I only have their HubSpot contact IDs?
      - Does the ID-based subscriber state update require the contacts to already exist?
      instructions:
      - text: Set contact IDs {inputs} to {subscriberState} for event {externalEventId} in account {externalAccountId}.
        slots:
          inputs: requestBody.inputs
          subscriberState: path.subscriberState

          externalAccountId: query.externalAccountId
      - text: By contact ID, mark {inputs} as {subscriberState} on marketing event {externalEventId} for account {externalAccountId}.
