Link two CRM records with the default association
with HubSpot
Works with AI assistants
Use HubSpot: its Hubspot Batch API lets you link two CRM records with the default association in a single step (PUT /crm/objects/2026-03/{fromObjectType}/{fromObjectId}/associations/default/{toObjectType}/{toObjectId}). 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 connect one CRM record to another with the standard, unlabeled association?
- Can I associate a single contact with a single company without picking a label?
Say it to your AI assistant
- Associate {from_object_type} {from_object_id} with {to_object_type} {to_object_id} using the default association.
- Create a default link from record {from_object_id} ({from_object_type}) to record {to_object_id} ({to_object_type}).
