n8n, Make, and Zapier Builds, Step by Step

Learning objectives

• Explain why n8n's Reddit node is action-only with no native trigger.
• Build a scheduled polling workflow monitoring multiple subreddits.
• Compare Make.com's and Zapier's Reddit triggers against n8n's polling approach.
• Use RSS/Apify as no-API-key ingestion paths when approval is a blocker.

Prerequisites: Lesson 5.2.2.

Core concepts

n8n has a Reddit ACTION node, submit posts, get comments, fetch subreddits/profiles, but no native TRIGGER node (docs.n8n.io). You cannot fire the instant a post appears; you must poll on a schedule, typically every one to three hours, and design deduplication around that gap.

The clearest teaching artifact: n8n template #5894 ("Reddit bot automation: AI auto-reply & post monitor with GPT-4 + Google Sheets," ~$25, creator harryhaz) monitors multiple subreddits on a 3-hour cycle, sends comment context to GPT-4.1 for genuine-need scoring, filters bots/moderators, drafts a reply, and logs to Google Sheets (n8n.io). Import and study it, but do the ethics exercise: as shipped it auto-replies. Identify where the human-approval gate belongs and rebuild it accordingly:

1. Schedule Trigger, every 3 hours (no native Reddit trigger)
2. Reddit node, Get Posts (subreddits: multiple, sort: new)
3. Filter node, dedupe against logged post IDs
4. LLM node, score context 0-100 for buying intent; exclude bots/mods
5. IF node, score > threshold, continue; else stop
6. Google Sheets node, append URL, score, excerpt, timestamp
7. Slack node, post a digest tagging a human reviewer
8. [Manual, outside n8n], human drafts/edits and posts the reply

For teams hitting the 2-4 week approval wait: Reddit RSS feeds (.rss on any subreddit/search URL) and Apify scrapers feed directly into n8n/Make/Zapier without an approved OAuth app, a real workaround, though a stopgap, not a permanent architecture. Apply for proper access in parallel.

For a lighter no-code build: Make.com's Reddit module triggers on a new/updated link in a subreddit and routes to Discord, Notion, or Sheets (make.com). Zapier covers the same ground with "new post or comment matching search," and also hosts Reddit's native Lead Generation Ads integration, Reddit Lead Ads connects to 8,000+ apps via Zapier; in beta, LaunchDarkly saw a 30% CPL reduction and 25% more lead submissions (intelligencygroup.com).

Exercise

Import template #5894 or build the 8-step sequence in n8n/Make/Zapier, holding the reply step for human approval instead of auto-posting. Run 24 hours against your five anchor subreddits and log results.

Assignment

Write a workflow-architecture doc: chosen tool and why, polling interval and its latency tradeoff, deduplication method, and the exact human-review point before anything posts.

Claude workflow

• Skill idea: a workflow-auditor skill flagging any step that posts/comments/DMs without a preceding human-review node.
• Automation opportunity: steps 1-6 above are safely automatable end to end; only step 8 (posting) must stay manual.

Expected outcomes

• Working monitoring workflow with a 24-hour run log.
• Explains why n8n's Reddit node requires polling, not a trigger.
• Workflow-architecture doc marking the human-approval gate.
