Works with AI assistants
Use HubSpot: its Hubspot Advanced API lets you merge two records of any object type in a single step (POST /crm/objects/2026-03/{objectType}/merge). 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 merge two duplicate records of a custom object type?
- Is there one merge endpoint that works for whichever object type I pass in?
Say it to your AI assistant
- Merge {objectType} record {objectIdToMerge} into {primaryObjectId}.
- Combine duplicate {objectType} records, keeping {primaryObjectId} as the primary.
