HubSpot Duplicate Merge Guardian with Field-Survivorship Review Queue
Detects likely-duplicate HubSpot contacts, builds a field-by-field survivorship proposal (which value wins per field).
How it runs
The automated pipeline, trigger to output.
- TriggerHubSpot contact created or updatedHubSpot
- ActionSearch HubSpot for duplicate candidates by email, phone, nameHubSpot
- LogicBranch: exit if no strong match, else build survivorship proposal
- ActionPost per-field merge proposal to Slack review queueSlack
- ActionOn approval, call HubSpot merge APIHubSpot
- OutputLog surviving record and merge decision
What it does
It watches HubSpot for newly created or updated contacts, finds probable duplicates, and turns the messy merge decision into a clean approval. Instead of auto-merging and silently destroying data, it produces a per-field survivorship proposal and routes it to a human queue.
When to use it
Use it when your team imports lists or captures leads from multiple sources and you want clean records without risking data loss from a blind auto-merge. Ideal for RevOps teams that need an audit trail for every merge decision.
How it works
- 1A new or updated HubSpot contact fires the trigger.
- 2The flow searches HubSpot for matches on normalized email, phone, and name to find duplicate candidates.
- 3A logic step branches: if no strong match, it exits quietly; if matches exist, it continues.
- 4For each conflicting field (name, title, owner, lifecycle stage), it picks a winner using recency and completeness rules and assembles a survivorship proposal.
- 5The proposal posts to a Slack channel with Approve/Reject actions and a clear before/after diff.
- 6On approval the flow calls the HubSpot merge API and logs the surviving record.
