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
externalAccountId: query.externalAccountId
- text: 'Using email addresses, record {subscriberState} for these attendees of event {externalEventId} (account {externalAccountId}): {inputs}.'

update:
x-apievangelist-phrasing:
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
externalEventId: path.externalEventId
externalAccountId: query.externalAccountId
- text: By contact ID, mark {inputs} as {subscriberState} on marketing event {externalEventId} for account {externalAccountId}.
slots:
inputs: requestBody.inputs
subscriberState: path.subscriberState
externalEventId: path.externalEventId
externalAccountId: query.externalAccountId
