Simply send a URL to the webhook endpoint, and the workflow will fetch the page content, process it through Google's entity recognition service, and return the structured entity data.\n\n### How to use\n1. Replace \"YOUR-GOOGLE-API-KEY\" with your actual Google Cloud API key (Natural Language API must be enabled)\n2. Activate the workflow and use the webhook URL as your endpoint\n3. Send a POST request to the webhook with a JSON body containing the URL you want to analyze: {\"url\": \"https://example.com/page\"}\n4. Review the returned entity analysis with categories, salience scores, and metadata\n\n## Webhook Input Format\nThe webhook expects a POST request with a JSON body in this format:\n```json\n{\n  \"url\": \"https://website-to-analyze.com/page\"\n}\n```\n### Response Format\nThe webhook returns a JSON response containing the full entity analysis from Google's Natural Language API, including:\n\nEntity names and types (PERSON, LOCATION, ORGANIZATION, etc.)\nSalience scores indicating entity importance\nMetadata and mentions within the text\nEntity sentiment (if available)"}, "typeVersion": 1}, {"id": "79add9a7-adca-4ce5-8a6a-5fcb75288846", "name": "Get Url", "type": "n8n-nodes-base.webhook", "position": [360, -420], "webhookId": "2944c8f6-03cd-4ab8-8b8e-cb033edf877a", "parameters": {"path": "2944c8f6-03cd-4ab8-8b8e-cb033edf877a", "options": {}, "httpMethod": "POST", "responseMode": "responseNode"}, "typeVersion": 2}, {"id": "081a52bc-2da7-44fb-bdc3-4cb73cbf8dd3", "name": "Get URL Page Contents", "type": "n8n-nodes-base.httpRequest", "position": [580, -420], "parameters": {"url": "={{ $json.body.url }}", "options": {}}, "typeVersion": 4.2}, {"id": "dda5ef3d-f031-4dd6-b117-c1f69aa66b63", "name": "Respond with detected entities", "type": "n8n-nodes-base.code", "position": [800, -420], "parameters": {"jsCode": "// Clean and prepare HTML for API request\nconst html = $input.item.json.data;\n// Trim if too large (optional)\nconst trimmedHtml = html.length > 100000 ? html.substring(0, 100000) : html;\n\nreturn {\n  json: {\n    apiRequest: {\n      document: {\n        type: \"HTML\",\n        content: trimmedHtml\n      },\n      encodingType: \"UTF8\"\n    }\n  }\n}"}, "typeVersion": 2}], "active": false, "pinData": {}, "settings": {"executionOrder": "v1"}, "versionId": "432203af-190a-4a89-81d8-f86682a0b63f", "connections": {"Get Url": {"main": [[{"node": "Get URL Page Contents", "type": "main", "index": 0}]]}, "Google Entities": {"main": [[{"node": "Respond to Webhook", "type": "main", "index": 0}]]}, "Get URL Page Contents": {"main": [[{"node": "Respond with detected entities", "type": "main", "index": 0}]]}, "Respond with detected entities": {"main": [[{"node": "Google Entities", "type": "main", "index": 0}]]}}}
