"content": "## AI Lead Classifier for GoHighLevel using Claude and Slack\n\nEvery new contact that lands in GoHighLevel gets scored, tagged, and routed automatically -- no manual lead sorting, no missed hot leads.\n\n### How it works\n\n1. GoHighLevel fires a webhook the moment a new contact is created in your account.\n2. The Settings node defines your ideal customer profile -- niche, company size, budget signals, and any keywords that indicate a strong or weak fit.\n3. Claude Sonnet reads the contact details and returns a score from 1 to 10, a tier label (Hot, Warm, or Cold), a one-line reasoning, and a recommended next action.\n4. A Switch node routes the contact into one of three branches based on their tier.\n5. Hot leads (score 7-10) trigger an instant Slack alert with the contact summary and fire an HTTP Request to update the GHL contact with a Hot Lead tag and move them to the correct pipeline stage.\n6. Warm leads (score 4-6) get tagged as Warm Lead and moved to a nurture stage in GHL via API.\n7. Cold leads (score 1-3) get tagged as Cold Lead and are moved to a low-priority stage.\n8. Every contact -- regardless of tier -- is logged to Google Sheets with the score, tier, reasoning, and timestamp.\n\n### Setup steps\n\n- [ ] **GoHighLevel webhook** -- In GHL go to Settings, Integrations, Webhooks and create a new webhook. Paste the URL from the Receive GHL Contact node and set the trigger to Contact Created. Activate this workflow first so the URL is generated.\n- [ ] **GHL API key** -- In GHL go to Settings, API Keys and create a new key. Paste it into the GHL API Key field in the Configure ICP and Settings node.\n- [ ] **GHL Location ID** -- Copy your Location ID from GHL Settings and add it to the Configure ICP and Settings node.\n- [ ] **Settings node** -- Open Configure ICP and Settings and fill in your niche, target company size, keywords that signal a good fit, and keywords that signal a poor fit.\n- [ ] **Claude AI** -- Click the Claude Sonnet sub-node under Classify Lead with Claude, add a new Anthropic credential, and paste your API key from console.anthropic.com.\n- [ ] **Slack** -- Connect your Slack account in Notify Team - Hot Lead and set your channel. Right-click and Disable this node if you do not use Slack.\n- [ ] **Google Sheets** -- Create a sheet called GHL Lead Log with columns: Timestamp, Name, Email, Phone, Source, Score, Tier, Reasoning, Next Action. Connect your Google account in Log Lead to Sheets.\n- [ ] Activate the workflow and create a test contact in GHL to verify all three branches work correctly.\n\n### Customization\n\nAdjust the Hot and Warm score thresholds in the Route by Tier switch node to match your standards. Add GHL pipeline IDs to the HTTP Request nodes to move contacts between pipeline stages automatically. Swap Claude Sonnet for Claude Haiku to reduce cost if lead volume is very high."
