Enrich HubSpot companies with Polish CEIDG data using NIP identifiers

This workflow automatically enriches HubSpot company records with official data from the Polish CEIDG (Central Register and Information on Economic Activity) database when a NIP (Polish Tax ID) is added or updated. Who's it for Polish sales teams, marketing agencies, and CRM administrators who work with Polish companies in HubSpot and want to save time on manual data entry while ensuring data accuracy. How it works 1. Trigger: Monitors HubSpot for changes to the "NIP" property on company records 2. Validation: Checks if the NIP field is not empty 3. API Query: Fetches official company data from the Polish CEIDG database using the provided NIP 4. Data Check: Verifies if company data was successfully retrieved 5. Transform: Maps CEIDG data to HubSpot company properties 6. Update: Enriches the HubSpot company record with: - Company name - Full address (street, city, postal code, state) - Phone number - Website URL - NIP and REGON numbers - Business start date 7. Error Handling: If NIP is invalid or no data found, adds a note to the company record Requirements - HubSpot account with: - Custom property "nip" created for companies - Custom property "ceidgnotes" created for companies (optional, for storing API notes) - App token or developer API credentials - CEIDG API Token (free registration at - n8n instance (self-hosted or cloud) How to set up 1. Create HubSpot custom properties: - Go to HubSpot Settings > Properties > Company Properties - Create a "nip" property (single-line text) - Create a "ceidgnotes" property (multi-line text) for storing API responses 2. Get CEIDG API Token: - Register at - Navigate to API section and generate your token - Add token to n8n credentials (HTTP Bearer Auth) 3. Configure HubSpot credentials: - Add your HubSpot App Token in n8n credentials - Or use HubSpot Developer API credentials 4. Activate the workflow: - Import this workflow to your n8n instance - Configure the credentials in all HubSpot and HTTP nodes - Activate the workflow 5. Test: - Add or update a NIP value in any HubSpot company record - Check if the company data gets automatically populated How to customize - Add more fields: Modify the "Transform data for HubSpot" Code node to map additional CEIDG fields - Change trigger property: Update the HubSpot Trigger to monitor a different property name - Notification: Add an email or Slack notification node after successful updates - Batch processing: Add a schedule trigger to process multiple companies at once - Data validation: Add nodes to validate NIP format before making the API call - Logging: Add a Google Sheets or database node to log all enrichment activities Notes - CEIDG database contains data for sole proprietorships registered in Poland - For limited liability companies (sp. z o.o.) and other entities, you'll need to use KRS (National Court Register) API instead - The workflow processes one company at a time as they are updated - API rate limits apply based on your CEIDG API plan
