HubSpot Fuzzy-Match Duplicate Merge with Slack Approval
Detects likely-duplicate HubSpot contacts using fuzzy name and email matching, then asks an operator to approve or reject each merge in Slack before anything is combined.
How it runs
The automated pipeline, trigger to output.
- TriggerNew or updated HubSpot contactHubSpot
- ActionSearch HubSpot for existing similar contactsHubSpot
- LogicScore fuzzy match; keep pairs above threshold
- ActionPost candidate pair to Slack with Approve/RejectSlack
- LogicWait for human decision
- ActionMerge approved contacts in HubSpotHubSpot
- OutputConfirm merge in Slack threadSlack
What it does
Scans newly created or updated HubSpot contacts, finds probable duplicates already in your CRM, and routes every candidate pair to a Slack channel where a human approves or rejects the merge. No contact is ever merged automatically.
When to use it
Use this when your sales and marketing forms create overlapping records (typos, work vs. personal email, name variants) and you want dedupe hygiene without risking a bad automated merge that destroys lifecycle data.
How it works
- 1A new or updated HubSpot contact fires the trigger.
- 2The flow searches HubSpot for existing contacts and scores each against the new one on name, email, and company similarity.
- 3A logic step keeps only pairs above the fuzzy-match confidence threshold; below it, the run ends silently.
- 4Each surviving pair is posted to Slack with key fields side by side and Approve / Reject buttons.
- 5On approval, the flow calls HubSpot's merge API to combine the records, keeping the older one as primary.
- 6A confirmation with the surviving record link is posted back to the Slack thread.
