I built an n8n workflow that creates and publishes YouTube videos automatically — from script to upload

Hey community! I’ve been working on a fully automated YouTube content pipeline using n8n, and I wanted to share the architecture with you all.

The Pipeline

Trigger (Schedule/Telegram)
  → AI Script Generation (GPT-4o/Claude via HTTP Request)
  → ElevenLabs TTS Voiceover
  → Pexels Stock Footage Search
  → Shotstack Video Assembly
  → YouTube Data API Upload
  → Telegram Notification
  → Google Sheet Status Update

How it works

  1. Trigger — I use a Telegram bot webhook. Sending “yap” to the bot starts the workflow. You can also use a schedule trigger for daily posts.

  2. AI Script — n8n’s HTTP Request node calls GPT-4o-mini with a structured system prompt. The key is requesting JSON output with intro_text, voiceover_segments[], image_prompts[], and outro_text. Without structured output you get a blob you can’t parse.

  3. ElevenLabs TTS — Each voiceover segment goes to ElevenLabs via HTTP Request. Turbo v2 generates ~10min of audio in 2 minutes. ~$0.30 per 10-min video.

  4. Stock Footage — Pexels API searches for each image_prompt. Falls back to Gemini Imagen/DALL-E if no results. All automated — never touch a download button.

  5. Video Assembly — Shotstack API takes a JSON timeline and renders the MP4. Timeline structure: silent intro → section 1 (audio+video) → section 2 → … → outro. ~3-5 min render for a 10-min video.

  6. YouTube Upload — YouTube Data API v3. Uploads as unlisted first for review. :warning: Quota warning: 1 upload = 1,600 units, daily limit = 10,000.

  7. Notification + Tracking — Telegram tells me when it’s done. Google Sheet tracks status so nothing gets re-processed.

Error Handling (critical!)

Without proper error handling, one API failure kills the entire pipeline. I use:

  • n8n Error Workflow trigger (catches ANY node failure)
  • Retry on Fail for critical nodes (ElevenLabs, Shotstack)
  • State tracking in Google Sheet (script_done → voice_done → video_done)
  • Resume from last checkpoint on failure

Best Niches for Faceless AI Channels

  • Top 10 lists (evergreen, simple structure)
  • News commentary (timely, high engagement)
  • Educational explainers (high retention)
  • Motivational content (high shareability)
  • Fact channels (fast production, high volume)

Monetization

  1. YouTube AdSense ($1–$5 CPM)
  2. Sell the n8n workflow template ($29–$49)
  3. n8n cloud affiliate ($10–$20/referral)
  4. Done-for-you service ($500–$2K/setup)

I’m happy to share more details about any part of the pipeline. What niche would YOU automate with n8n?
