Enrich Google Sheets with Dun & Bradstreet Data Blocks

Automate company enrichment directly in Google Sheets using Dun & Bradstreet (D&B) Data Blocks. This workflow reads DUNS numbers from a sheet, fetches a Bearer token (via Basic Auth → /v3/token), calls the Data Blocks API for each row (/v1/data/duns/...), extracts Paydex , and appends or updates the sheet. A Filter node skips rows already marked Complete for efficient, idempotent runs.

✅ What this template does

• Pulls DUNS values from a Google Sheet
• (Option A) Uses an HTTP Header Auth credential for D&B, or
  (Option B) Dynamically fetches a Bearer token from /v3/token (Basic Auth)
• Calls D &B Data Blocks per row to retrieve payment insights
• Extracts Paydex and upserts results back to the sheet
• Skips rows already Complete

👤 Who's it for

• RevOps/Data teams enriching company lists at scale
• SDR/Marketing teams validating firmographic/credit signals
• BI/Automation builders who want a no-code/low-code enrichment loop

🧩 How it works (node-by-node)

1. Get Companies (Google Sheets) – Reads rows with at least duns, paydex, Complete.
2. Only New Rows (Filter) – Passes only rows where Complete is empty.
3. D &B Info (HTTP Request) – Calls Data Blocks for each DUNS using a header credential (Authorization: Bearer <token>).
4. Keep Score (Set) – Maps nested JSON to a single Paydex field:
   {{$json.organization.businessTrading[0].summary[0].paydexScoreHistory[0].paydexScore}}
5. Append to g-sheets (Google Sheets) – Append or Update by duns, writing paydex and setting Complete = Yes.

The workflow also includes Sticky Notes with in-canvas setup help.

🛠️ Setup instructions (from the JSON)

1) Connect Google Sheets (OAuth2)

1. In n8n → Credentials → New → Google Sheets (OAuth2) and sign in.
2. Use/prepare a sheet with columns like: duns , paydex , Complete.
3. In your Google Sheets nodes, select your credential and target spreadsheet/tab.
4. For upsert behavior, set Operation to Append or Update and Matching column to duns.

Replace any example Sheet IDs/URLs with your own (avoid publishing private IDs).

2) Get a D&B Bearer Token (Basic Auth → /v3/token) — Optional Dynamic Token Node

1. Add/enable HTTP Request node named Get Bearer Token1.
2. Configure:
   • Authentication: Basic Auth (your D&B username /password)
   • Method: POST
   • URL: https://plus.dnb.com/v3/token
   • Body Parameters: grant_type = client_credentials
   • Headers: Accept = application/json
3. Execute to receive access_token.
4. Reference the token in other nodes via:
   Authorization: Bearer {{$node["Get Bearer Token1"].json["access_token"]}}

⚠️ Security: Don't hardcode tokens. Prefer credentials or fetch dynamically.

3) Call D&B Data Blocks (use Header Auth or dynamic token)

Node: D&B Info (HTTP Request)

• Authentication: Header Auth (recommended)

• URL:

  https://plus.dnb.com/v1/data/duns/{{ $json.duns }}?blockIDs=paymentinsight_L4_v1&tradeUp=hq&customerReference=customer%20reference%20text&orderReason=6332
  

• Headers:

  • Accept = application/json
  • If not using a stored Header Auth credential, set:
    Authorization = Bearer {{$node["Get Bearer Token1"].json["access_token"]}}

{{ $json.duns }} is resolved from the current row provided by Get Companies.

---

4) Map Paydex and Upsert to Google Sheets

• Keep Score (Set)

  • Field Paydex (Number):

          {{$json.organization.businessTrading[0].summary[0].paydexScoreHistory[0].paydexScore}}
    

• Append to g-sheets (Google Sheets)

  • Operation: Append or Update
  • Matching column: duns
  • Columns mapping:
    • duns = {{ $('Get Companies').item.json.duns }}
    • paydex = {{ $json.Paydex }}
    • Complete = Yes

---

🧪 Test checklist

• Add a few test DUNS rows (leave Complete blank).
• Run the workflow and confirm Only New Rows passes expected items.
• Check D &B Info returns payment insight data.
• Confirm Paydex is set and the row is updated with Complete = Yes.

---

🔐 Security & best practices

• Store secrets in Credentials (HTTP Header Auth/Basic Auth).
• Avoid publishing real Sheet IDs or tokens in screenshots/notes.
• Consider rate limits and backoff for large sheets.
• Log/handle API errors (e.g., invalid DUNS or expired tokens).

---

🩹 Troubleshooting

• 401/403 from D &B: Verify credentials/token; ensure correct environment and entitlements.
• Missing Paydex path: D&B responses vary by subscription/data availability—add guards (IF node) before mapping.
• Rows not updating: Confirm Append or Update is used and Matching column exactly matches your sheet header duns.
• Filtered out rows: Ensure Complete is truly empty (no spaces) for new items.

---

🧯 Customize further

• Enrich additional fields (e.g., viability score , portfolio comparison , credit limits).
• Add retry logic, batching, or scheduled triggers.
• Push results to a CRM/DB or notify teams via Slack/Email.
