DNC Scrub Completed

When a DNC scrub completes, Tracerfy POSTs the result to the webhook URL configured in your account profile. The payload includes a type: "dnc_scrub" field to distinguish it from trace webhooks, plus DNC-specific fields like clean_download_url, phones_checked, and phones_clean. Tracerfy sends this JSON to your Account.webhook_url when a DNC scrub completes.
