Score ATS Candidates & Automate Outreach Campaigns in n8n

Score ATS Candidates Automatically—and Launch Outreach Campaigns from n8n

This n8n workflow receives a new job order from your ATS, optionally uses Anthropic to extract job requirements, finds and scores matching candidates, checks Supabase suppression/engagement history, then upserts a scheduled outreach campaign—with an optional Slack launch summary.

What this workflow does

• Ingests job orders via webhook: Listens for “job order created” events (or runs manually) and normalizes the payload into a consistent job spec using your configured ATS field mapping.
• Extracts skills with Anthropic (optional): If the job order lacks enough structured skills, calls the Anthropic Messages API to extract required and preferred skills, then merges them back into the job spec.
• Searches candidates in your ATS: Uses your ATS API to retrieve candidates (or falls back to a built-in sample candidate pool when the ATS isn’t connected).
• Scores matches with clear reasons: Normalizes candidates (including E.164 phone formatting), excludes ineligible statuses, deduplicates results, and computes a transparent match score with human-readable explanations.
• Gates outreach using Supabase: Fetches opt-outs, recent touches, and active enrollments from Supabase to suppress candidates who shouldn’t be contacted (or uses demo/empty history if Supabase isn’t configured).
• Upserts campaign + enrollments: Writes the job order, campaign, and candidates into Supabase, links IDs, and inserts enrollment rows with the first touch scheduled (not sent).
• Optionally posts to Slack: Sends a formatted launch summary to Slack after the campaign is created.

Use cases

• Recruiting teams that want ATS-to-campaign automation when a new role opens.
• SaaS operators who need controlled outreach with suppression rules and engagement history tracking in Supabase.
• Automation engineers building repeatable n8n workflows for candidate matching and campaign scheduling.

Technical details
