List lists tied to an event by its external IDs

Works with AI assistants

Use HubSpot: its Marketing Marketing Events List Associations API lets you list lists tied to an event by its external IDs in a single step (GET /marketing/marketing-events/2026-09/associations/{externalAccountId}/{externalEventId}/lists). 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.

• Which contact lists are linked to a marketing event from my external event app?
• Can I see an event's associated lists using my own external account and event IDs?

Say it to your AI assistant

• List the lists associated with external event {externalEventId} in external account {externalAccountId}.
• Show which lists are attached to my app's event {externalEventId} under account {externalAccountId}.
