returns error if missing\n3. **Data normalization** extracts and structures all measurement fields with defaults for optional values\n4. **Success response** confirms receipt immediately (200 OK)\n5. **Routing** directs data to one of four outputs based on the outputMode setting:\n - **sheets**: Appends to Google Sheets for tracking and analysis\n - **html**: Returns formatted HTML table for browser viewing\n - **csv**: Emails CSV file attachment to specified recipient\n - **custom**: Runs JavaScript code for API calls, cloud storage, or custom logic\n\n## Setup steps:\n1. **Configure output mode**: Edit \"Workflow Configuration\" node and set outputMode to your preferred destination\n2. **Google Sheets** (if using sheets mode): Add Google Sheets credentials and update googleSheetId with your sheet ID\n3. **Email** (if using csv mode): Add SMTP credentials and set emailRecipient to the destination address\n4. **Custom code** (if using custom mode): Modify the JavaScript node with your integration logic\n5. **Test**: Send a POST request to the webhook URL with sample measurement data\n\n\n\n## How to get the Webhook URL:\n- **Double click** on the 1st node **Webhook Trigger - Receive Measurement Data**\n- You can see Test / Production URL section at the top in drop down \u2304 Webhook URLs\n**Ex.** Webhook URL format: https://{your-cloud-name}.app.n8n.cloud/webhook/measurement-data\n\n\n## How to take measurements:\n- Import and activate the workflow in n8n. \n- Copy the **Webhook URL** from the Webhook Trigger node. \n- Open the **3D Measure Up Web Application**: https://3dmeasureup.ai/ \n- Log in and navigate to **Settings \u2192 Webhooks**. \n- Paste the webhook URL into the **Webhook URL** field and click **Save**. \n\n### Now, whenever you take a measurement with 3D Measure Up, it will be available in your n8n workflow" }, "typeVersion": 1 }, { "id": "acafb3fd-947c-4782-966e-ee185bffd5e9", "name": "Webhook Trigger - Receive Measurement Data", "type": "n8n-nodes-base.webhook", "position": [ -5488, -864 ], "parameters": { "path": "measurement-data", "options": {}, "httpMethod": "POST", "responseMode": "lastNode" }, "typeVersion": 2.1, "alwaysOutputData": false }, { "id": "fe53a33d-c1ad-4bd3-a4b9-a90a7111882e", "name": "Send Error Response", "type": "n8n-nodes-base.respondToWebhook", "position": [ -4192, -368 ], "parameters": { "options": { "responseCode": 400 }, "respondWith": "json", "responseBody": "{\n \"success\": false,\n \"error\": \"Missing required fields: measurementId, timestamp, values\"\n}" }, "typeVersion": 1.5 }, { "id": "4aa05768-a3a3-460f-b5ea-d203bcd8af01", "name": "Error - Invalid Payload", "type": "n8n-nodes-base.stopAndError", "position": [ -4192, -576 ], "parameters": { "errorMessage": "Invalid payload: Missing required fields (measurementId, timestamp, values)" }, "typeVersion": 1 }, { "id": "1930f36c-1b48-4938-8f5e-fe4547023825", "name": "Workflow Configuration", "type": "n8n-nodes-base.set", "position": [ -4976, -864 ], "parameters": { "options": {}, "assignments": { "assignments": [ { "id": "id-1", "name": "outputMode", "type": "string", "value": "sheets" }, { "id": "id-2", "name": "googleSheetId", "type": "string", "value": "YOUR_SHEET_ID_HERE - Please replace with your actual Google Sheet ID" }, { "id": "id-3", "name": "emailRecipient", "type": "string", "value": "user@example.com" }, { "id": "id-4", "name": "emailSubject", "type": "string", "value": "Measurement Data Export" } ] }, "includeOtherFields": true }, "typeVersion": 3.4 } ], "active": false, "settings": { "binaryMode": "separate", "availableInMCP": false, "executionOrder": "v1" }, "versionId": "69b60df7-a90e-44a3-b804-908bc6ec5e1c", "connections": { "Convert to CSV File1": { "main": [ [ { "node": "Send Email with CSV1", "type": "main", "index": 0 } ] ] }, "Generate HTML Table1": { "main": [ [ { "node": "Return HTML Page1", "type": "main", "index": 0 } ] ] }, "Send Success Response1": { "main": [ [ { "node": "Route to Output Options1", "type": "main", "index": 0 } ] ] }, "Workflow Configuration": { "main": [ [ { "node": "Validate Required Fields1", "type": "main", "index": 0 } ] ] }, "Route to Output Options1": { "main": [ [ { "node": "Save to Google Sheets1", "type": "main", "index": 0 } ], [ { "node": "Generate HTML Table1", "type": "main", "index": 0 } ], [ { "node": "Convert to CSV File1", "type": "main", "index": 0 } ], [ { "node": "Custom JavaScript Logic1", "type": "main", "index": 0 } ] ] }, "Parse and Normalize Data1": { "main": [ [ { "node": "Send Success Response1", "type": "main", "index": 0 } ] ] }, "Validate Required Fields1": { "main": [ [ { "node": "Parse and Normalize Data1", "type": "main", "index": 0 } ], [ { "node": "Error - Invalid Payload", "type": "main", "index": 0 }, { "node": "Send Error Response", "type": "main", "index": 0 } ] ] }, "Webhook Trigger - Receive Measurement Data": { "main": [ [ { "node": "Workflow Configuration", "type": "main", "index": 0 } ] ] } } }
