Unlink a list from an event by its external IDs

Works with AI assistants

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

• How do I detach a list from a marketing event I track by external event ID?
• Can I remove a list association using my external account and event IDs instead of the HubSpot event ID?

Say it to your AI assistant

• Disassociate list {listId} from external event {externalEventId} in external account {externalAccountId}.
• Detach list {listId} from my app's event {externalEventId} under account {externalAccountId}.
