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\": \"{{ $env.WEBHOOK_URL }}\"}\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\": \"{{ $env.WEBHOOK_URL }}\"\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,"notes":"This stickyNote node performs automated tasks as part of the workflow."},{"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,"notes":"This webhook node performs automated tasks as part of the workflow."},{"id":"081a52bc-2da7-44fb-bdc3-4cb73cbf8dd3","name":"Get URL Page Contents","type":"n8n-nodes-base.httpRequest","position":[580,-420],"parameters":{"url":"{{ $env.BASE_URL }}","options":{}},"typeVersion":4.2,"notes":"This httpRequest node performs automated tasks as part of the workflow."},{"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,"notes":"This code node performs automated tasks as part of the workflow."}],"active":false,"settings":{"executionOrder":"v1","saveManualExecutions":true,"callerPolicy":"workflowsFromSameOwner","errorWorkflow":null,"timezone":"UTC","executionTimeout":3600,"maxExecutions":1000,"retryOnFail":true,"retryCount":3,"retryDelay":1000},"versionId":"432203af-190a-4a89-81d8-f86682a0b63f","connections":{"Respond to Webhook":{"main":[[],[],[],[],[]]},"Google Entities":{"main":[[],[],[],[],[]]},"Get Url":{"main":[[],[],[],[],[]]},"Get URL Page Contents":{"main":[[],[],[],[],[]]}},"description":"Automated workflow: Google Page Entity Extraction Template.
