What it does

Verify domain legitimacy, detect potential threats with reverse IP lookups, and enrich company records with registrant data and DNS history.

Who Is is a SyncGTM native integration — it runs on SyncGTM credits, so there is no external Who Is account or API key to connect.

Adding the integration creates an Action column. It behaves like any other Action column — same dynamic variables, same Auto Run triggers, same per-row test before you run the whole column.

Available actions

ActionWhat it does
Get Domain DetailsFetch WHOIS data like registrar info, creation date, and expiry for any domain.
Domain Threat DetectionAnalyze domains for potential threats and suspicious registration activity.
Get Brand Alert CreditsCheck available credits for tracking brand mentions across domains.
Reverse IP LookupFind all domains hosted on the same IP address as the target domain.

Each action is its own column. Pick the one you need when you add the integration — you can add more than one from the same integration to a table.

Setup

  1. Click Add Action in the top right of your table and open the Integrations tab.
  2. Select Who Is, then choose the action you want the column to run.
  3. Map the required inputs to your existing columns using dynamic variables.
  4. Choose whether to Auto Run the action. If you do, pick the trigger column that fires it.
  5. Test on the first row with the play button.
  6. Run the whole column from the ▶️ in the column header.
