CRM to Spreadsheet Sync

This workflow syncs HubSpot CRM contacts to Google Sheets. Key nodes include Webhook Trigger (receives requests), Validate Input (sets sync parameters), Input Validation Check (ensures valid input), Fetch CRM Contacts (queries HubSpot API), Transform Contact Data (formats data), Validate Contact Data (checks name/email), Save to Spreadsheet (appends to Google Sheets), Log Invalid Contact (logs invalid data), Aggregate Results (compiles results), Format Success Response (prepares success output), Success Response (returns success), Validation Error Handler (handles invalid input), CRM API Error Handler (handles HubSpot errors), Spreadsheet Error Handler (handles Google Sheets errors), Error Response (returns validation errors), API Error Response (returns API errors). It uses HubSpot and Google Sheets APIs.\n\nSetup Requirements: Install n8n from n8n.io or sign up at cloud.n8n.io. Import the JSON into n8n’s workflow editor. Create a HubSpot account at app.hubspot.com, get OAuth2 credentials (Integrations > API Key). Set up a Google Sheets spreadsheet with headers: Name, Email, Company, Phone, Last_Modified, Contact_ID, Sync_Date. Get Google Sheets OAuth2 credentials at console.developers.google.com (APIs > Credentials > OAuth 2.0 Client). Configure n8n credentials: HubSpot (hubspotApi), Google Sheets (googleSheetsOAuth2Api). Set Webhook Trigger path to your-webhook-path with header authentication (Bearer YOUR_TOKEN). Configure your app to send POST requests with syncType (e.g., 'full'), optional lastSyncDate, and maxRecords (≤1000). Handle errors like missing body (400: VALIDATION_ERROR) or invalid HubSpot credentials (500: CRM_API_ERROR).\n\nTesting and Deployment: Import the JSON into n8n. Test by sending a POST request to the webhook URL with JSON: {\"syncType\": \"full\", \"maxRecords\": \"50\"} and a valid auth header. Verify that Fetch CRM Contacts retrieves data and Save to Spreadsheet appends valid contacts. Confirm Success Response returns status 200 with totalContactsFetched. Test with invalid input (maxRecords: \"2000\") to trigger Error Response (400: VALIDATION_ERROR). Test with incorrect HubSpot credentials (500: CRM_API_ERROR) or Google Sheets credentials (500: SPREADSHEET_ERROR). Monitor for rate limits (429: Too Many Requests). If data doesn’t save, verify the spreadsheet ID. Activate the workflow and ensure the webhook is live. Deploy for reliable CRM sync.
