It reads conversions from your source, hashes the identifiers that require it, and routes each to the right platform.\n\n### How it works\n- Reads backend conversions from your source (example rows included; swap in Supabase, Postgres or Google Sheets).\n- Hashes only the PII the platforms require (email, phone, name, city, state, zip, country) in one loop through the native Crypto node (SHA-256). external_id and device or click IDs (fbc, fbp, IP, user agent) pass through unhashed, per the Meta and Google specs.\n- Regroups the hashed and plain fields per conversion.\n- A source switch routes by destination tag: Meta to the Meta Conversions API, Google to Google Ads, both to both.\n\n### Setup\n1. Edit the Set config node: Meta pixel ID, Google Ads customer ID, conversion action, versions. Set test_event_code to test via Meta Test Events.\n2. Add secret tokens to your n8n env: META_ACCESS_TOKEN, GOOGLE_ADS_ACCESS_TOKEN, GOOGLE_ADS_DEVELOPER_TOKEN.\n3. Replace the example source node with your data.\n\n### Customization\nOnly ever send first-party, consented data.\n\nBuilt by **nocode.expert** \u2014 done-for-you automation & tracking. https://nocode.expert" }, "typeVersion": 1 }, { "id": "section-source-normalize", "name": "Section: Source & normalize", "type": "n8n-nodes-base.stickyNote", "position": [ 256, 160 ], "parameters": { "color": 7, "width": 508, "height": 416, "content": "## 1.
