Apify Reddit Keyword Monitor → LinkedIn Ideas to Notion

Turn Apify Reddit keyword insights into LinkedIn content ideas in Notion

This n8n workflow listens for Apify Reddit Keyword Monitor webhooks, pulls the most relevant matched Reddit posts, uses Anthropic Claude to generate one LinkedIn idea per keyword theme, and automatically logs everything into a Notion content calendar—with Slack alerts if anything fails.

What this workflow does

• Receives Apify webhook notifications: When the Apify actor run completes, it accepts a POST webhook, immediately responds “OK” to acknowledge receipt.
• Fetches matched Reddit posts: Using the Apify API, it retrieves up to 200 matched Reddit posts from the run’s default dataset.
• Groups by keyword theme: Posts are grouped by the matched keyword theme, then the workflow selects the highest engagement-velocity post as the representative for each theme.
• Generates LinkedIn ideas with Anthropic Claude: For each theme, it sends the top post context to Anthropic Claude to produce a JSON response containing a LinkedIn hook, angle, content type, and estimated performance.
• Writes to Notion: It parses Claude’s output (with a fallback if parsing fails) and creates a new page in a Notion database including idea details, the source Reddit post URL, subreddit, status, and date added.
• Alerts on failures: If the Apify fetch or Claude request errors occur, it posts a formatted Slack message to notify you.

Use cases

• Content teams turning Reddit keyword trends into weekly LinkedIn posts, automatically tracked in Notion.
• SaaS operators monitoring market conversations via Apify and converting themes into publication-ready angles.
• Automation engineers building a reliable pipeline with webhook-driven enrichment, AI generation, and calendar logging.
