Push GitHub Leads to Hunter.io: Signal + Email Finding Combined

GitLeads + Hunter.io: Signal First, Then Email

Hunter.io finds email addresses. GitLeads finds developers showing buying signals on GitHub. Together, they form a complete top-of-funnel workflow for developer GTM: GitLeads identifies which developers are actively evaluating solutions (by starring repos or mentioning relevant keywords in issues), and Hunter.io confirms or enriches the professional email so your team can reach out through the right channel. Signal first — then contact enrichment. This is the right order for developer outreach.

The Workflow: From GitHub Signal to Enriched Contact

1. GitLeads monitors your tracked GitHub repos and keywords 24/7
2. A new star or keyword mention triggers a lead capture event
3. GitLeads enriches the lead with GitHub profile data (name, company, bio, top languages, followers)
4. Lead is pushed via webhook or Zapier/Make/n8n to Hunter.io Domain Search or Email Finder API
5. Hunter.io adds the professional email address and confidence score
6. Enriched, verified lead lands in HubSpot, Apollo, Instantly, or your outreach tool of choice

Sample Webhook Payload to Hunter.io via Make

// Webhook payload from GitLeads → Make scenario → Hunter.io API
// Step 1: GitLeads webhook delivers the raw signal
const gitLeadsPayload = {
  github_username: 'devuser42',
  name: 'Alex Kim',
  email: null, // may not have public email
  company: 'DevStartup Inc.',
  bio: 'Backend Engineer | Rust, K8s, Temporal',
  signal: "starred temporal/sdk-go",
  signal_context: "Star on temporal/sdk-go"
};

// Step 2: Use company domain from GitHub bio → Hunter.io Domain Search
// GET https://api.hunter.io/v2/domain-search?domain=devstartup.com&api_key=YOUR_KEY
const hunterResponse = {
  data: {
    emails: [
      {
        value: "alex@devstartup.com",
        confidence: 91,
        first_name: "Alex",
        last_name: "Kim",
        position: "Backend Engineer"
      }
    ]
  }
};

// Step 3: Merge and push to outreach tool
const enrichedLead = {
  ...gitLeadsPayload,
  email: hunterResponse.data.emails[0].value,
  email_confidence: hunterResponse.data.emails[0].confidence,
};

GitLeads vs Hunter.io: Complementary, Not Competing

Hunter.io finds emails from domains. GitLeads finds developers expressing intent on GitHub. Hunter.io without signal data means cold outreach to anyone at a company. GitLeads without email means you have a warm lead but no way to reach them. The combination is powerful: warm, intent-based signals from GitLeads + verified email from Hunter.io = outreach that converts. The developer already showed interest before you contacted them.

Setting Up the Integration via Zapier

• Trigger: GitLeads webhook → new lead captured
• Step 1: Extract company domain from GitHub bio using regex or company field
• Step 2: Call Hunter.io Domain Search API with company domain
• Step 3: Match name from GitLeads against Hunter.io results
• Step 4: Push enriched lead (signal + email) to HubSpot, Apollo, or Instantly
• Optional: Add confidence threshold filter (only send leads with >80% email confidence)
