Create default associations in bulk
with HubSpot
Works with AI assistants
Use HubSpot: its Hubspot Batch API lets you create default associations in bulk in a single step (POST /crm/associations/2026-03/{fromObjectType}/{toObjectType}/batch/associate/default). 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 link many record pairs using just the generic, unlabeled association type?
- Can I bulk associate deals to contacts without choosing association labels?
Say it to your AI assistant
- Create default associations from {from_object_type} to {to_object_type} for {record_pairs}.
- Link {record_pairs} between {from_object_type} and {to_object_type} with the most generic association.
