n8n Webhook JSON Tech Trends from Data Table

Get Today’s Tech Trends as JSON—Built for Desktop Widgets

This n8n workflow serves a CORS-enabled webhook endpoint that returns today’s tech trends as application/json. It reads rows from an n8n Data Table, splits results into news and YouTube lists, and responds with a ready-to-consume payload for your desktop widget or any client.

What this workflow does

• Receives an HTTP request via a webhook trigger.
• Queries the n8n Data Table named tech_trends and filters rows using the configured date logic.
• Separates items by source (YouTube vs. non-YouTube), sorts each group by rank, and builds two top-3 arrays of titles.
• Returns an HTTP 200 response with:
  • Content-Type: application/json
  • Access-Control-Allow-Origin: * (CORS-enabled)

Use cases

• Desktop widget data feed: Pull daily “tech trends” directly from n8n and render them in a widget UI.
• Productivity dashboards: Display top-ranked technology items with a clean JSON schema.
• SaaS operations & monitoring: Provide consistent trend data to multiple front-end clients without rebuilding logic.
• Automation engineers: Use it as a webhook + Data Table pattern for structured, date-driven responses.

Technical details

• Workflow trigger: webhook
• Data source: n8n Data Table (tech_trends) with fields for date, rank, title, and source
• Processing: Code step to split by source (YouTube vs. non-YouTube) and format news and youtube arrays
• Response node: “Respond to Webhook” with JSON output and CORS headers

Setup quick start

Activate the workflow, copy the production webhook URL into your desktop widget/client, populate the tech_trends Data Table, and ensure the Data Table query’s date filter matches your “today” definition.
