Works with AI assistants
Use HubSpot: its Marketing Marketing Events Event Attendees API lets you record attendance by email for a HubSpot event in a single step (POST /marketing/marketing-events/2026-09/{objectId}/attendance/{subscriberState}/email-create). HubSpot also has an MCP server, so an AI assistant like Claude or ChatGPT can do it for you. capabilities.work can help you get signed up and connected.
- Can I record attendees by email against a marketing event using its HubSpot object ID?
- If I record emails on an event by its internal ID, are the contact properties I send applied to existing contacts?
Say it to your AI assistant
- Record attendee emails {inputs} as {subscriberState} on marketing event {objectId}.
- Register emails {inputs} for HubSpot marketing event {objectId} with state {subscriberState}, creating contacts that don't exist.
