Ads Lead Capture

Capture leads from paid ad platforms (Meta Lead Ads, Google Ads Lead Forms, TikTok Lead Gen) and route them through validation, enrichment, scoring, and CRM upsert via n8n workflows.

When to Use

• "Set up lead capture from Facebook/Meta ads"
• "Connect Google Ads to CRM"
• "TikTok lead gen integration"
• "Ad leads aren't syncing to Attio"
• "Track ad spend per lead" or "calculate CAC"
• Building any ad platform to CRM pipeline

Platform Integration Patterns

Meta Lead Ads (Facebook/Instagram)

n8n Trigger Node: Facebook Lead Ads Trigger

{
  "node": "Facebook Lead Ads Trigger",
  "parameters": {
    "page": "={{$json.page_id}}",
    "form": "={{$json.form_id}}"
  },
  "credentials": {
    "facebookLeadAdsOAuth2Api": "Meta Ads"
  }
}

Field Mapping:

Meta Field	CRM Field
full_name	Split to first_name + last_name
email	email_addresses
phone_number	phone_numbers
company_name	company association
job_title	job_title
Custom: "What's your biggest challenge?"	Note on record

Google Ads Lead Form Extensions

n8n Trigger: Webhook node (Google Ads sends to webhook URL)

{
  "node": "Webhook",
  "parameters": {
    "path": "google-ads-lead",
    "httpMethod": "POST",
    "authentication": "headerAuth"
  }
}

Google Ads Webhook Setup:

1. Create lead form extension in Google Ads
2. Set webhook URL to n8n webhook endpoint
3. Add Google's webhook key for auth verification
4. Map: user_column_data array to CRM fields

TikTok Lead Gen

n8n Trigger: Webhook node (TikTok Instant Form webhook)

{
  "node": "Webhook",
  "parameters": {
    "path": "tiktok-lead",
    "httpMethod": "POST"
  }
}

TikTok Field Mapping:

TikTok Field	CRM Field
leads[].fields.name	first_name + last_name
leads[].fields.email	email_addresses
leads[].fields.phone_number	phone_numbers

Common Workflow Pattern

Ad Platform Trigger/Webhook
  → Parse & Normalize Fields
    - Split full_name to first/last
    - Normalize phone (add country code)
    - Extract UTM parameters
  → Validate Email
    - Regex check
    - Disposable email detection
    - Skip if invalid (log reason)
  → Enrichment Sub-workflow
    - Google Search (Apify)
    - Perplexity Sonar research
    - Company enrichment
  → Lead Scoring Engine
    - Channel score: Ads = 10 points
    - Add ICP + enrichment scores
  → Upsert to Attio
    - Person record (match by email)
    - Set lead_source based on platform
    - Set business_brand based on campaign/UTM
  → Route by Brand
    - Multi-brand router sub-workflow
    - Add to correct sales list
  → Notify
    - Telegram: new lead captured with score
    - If Hot: immediate alert

UTM Parameter Parsing

Extract attribution data from ad click URLs:

// n8n Code Node: Parse UTMs
const url = new URL($input.item.json.landing_page_url || '');
const utm = {
  source: url.searchParams.get('utm_source'),      // facebook, google, tiktok
  medium: url.searchParams.get('utm_medium'),       // cpc, paid_social
  campaign: url.searchParams.get('utm_campaign'),   // campaign name
  content: url.searchParams.get('utm_content'),     // ad creative ID
  term: url.searchParams.get('utm_term')            // keyword (Google)
};

// Map source to lead_source enum
const sourceMap = {
  'facebook': 'Social Media',
  'instagram': 'Social Media',
  'google': 'Direct',
  'tiktok': 'Social Media'
};

return {
  ...utm,
  lead_source: sourceMap[utm.source] || 'Direct',
  campaign_name: utm.campaign
};

Cost Tracking for CAC Calculation

Data to Capture Per Lead

Field	Source
ad_platform	UTM source or trigger type
campaign_id	UTM campaign or platform field
ad_set_id	Platform field
ad_creative_id	UTM content
cost_per_lead	Platform API (batch update daily)

Daily Cost Sync (n8n Workflow)

Schedule (daily 6am)
  → Meta Marketing API: get campaign spend by day
  → Google Ads API: get campaign cost by day
  → TikTok Ads API: get campaign cost by day
  → Calculate: total_spend / leads_captured = CPL
  → Store in Attio or Google Sheets for reporting

CAC Formula

CAC = Total Ad Spend / Number of Customers Acquired
Target CAC: < $50 for SMB, < $200 for mid-market

Retargeting Pixel Events

Fire pixel events at key conversion stages for ad platform optimization:

Stage	Meta Pixel Event	Google Tag	TikTok Pixel
Lead captured	Lead	generate_lead	SubmitForm
Lead qualified (score 60+)	CompleteRegistration	sign_up	CompleteRegistration
Proposal sent	InitiateCheckout	begin_checkout	InitiateCheckout
Deal won	Purchase	purchase	PlaceAnOrder

Implementation via n8n

Attio Webhook (deal stage changed)
  → Check new stage
  → If "qualified": fire Meta CAPI event, Google Offline Conversion
  → If "won": fire Purchase event with deal value

Lead Source Mapping by Platform

Platform	Campaign Naming Convention	Brand Detection
Meta	{brand}_{vertical}_{offer}_{date}	Extract from campaign name prefix
Google	{brand}_{keyword_theme}_{match_type}	Extract from campaign name prefix
TikTok	{brand}_{content_type}_{audience}	Extract from campaign name prefix

Quick Reference

Task	Method
Add Meta Lead Ads trigger	n8n: Facebook Lead Ads Trigger node
Add Google/TikTok trigger	n8n: Webhook node with platform-specific auth
Parse UTMs	Code node extracting URL search params
Track cost	Daily sync from platform APIs
Fire conversion events	n8n workflow on Attio stage change

Error Handling

• Invalid email: log to "rejected leads" sheet, do not upsert to CRM
• Duplicate lead: Attio upsert handles dedup by email, update existing record
• Webhook auth failure: return 401, alert via Telegram
• Enrichment timeout: upsert lead without enrichment, flag for re-enrichment
• Missing required fields: log partial data, create record with what's available
• Platform API rate limit: implement exponential backoff in n8n
