Every day at 8AM this workflow reads pending TikTok video URLs from your Google Sheet, checks if there are any to process, submits each to WayinVideo Summarization API, and stores per-video summaries. Once all videos are processed, a Code node aggregates all summaries into one combined string and GPT-4o-mini writes a clean daily digest \u2014 trend overview, per-video bullet points, top 3 content patterns, action recommendations, and trending tags. A Code node formats everything into a Telegram Markdown message with auto-truncation at 4000 characters. Telegram Bot sends the digest to your team channel. Google Sheets logs the digest and marks all processed videos.\n\n## How it works\n- **1. Schedule \u2014 Every Day 8AM** triggers the pipeline daily\n- **2. Google Sheets \u2014 Read Pending Videos** reads all rows from the Video Queue tab\n- **3. IF \u2014 Any Pending Videos Today?** stops the workflow cleanly if the queue is empty\n- **4\u20136. WayinVideo Summarization** submits each URL, waits 60 seconds, polls until SUCCEEDED\n- **7. IF \u2014 Summary Complete?** checks status \u2014 retries via 30-second wait if not ready\n- **9. Code \u2014 Extract Summary Per Video** extracts summary, highlights array, and tags per video\n- **10. Code \u2014 Aggregate All Summaries** collects all per-video items into one combined text string for GPT \u2014 this node sits above the main flow as it waits for all items\n- **11. AI Agent \u2014 Write Daily Digest** uses GPT-4o-mini to write a 5-section digest with trend overview, video summaries, top patterns, action recommendations, and top tags\n- **13. Code \u2014 Format Telegram Message** builds a Markdown-formatted Telegram message with section headers and auto-truncates at 4000 characters\n- **14. Telegram \u2014 Send Daily Digest** sends the message to your team channel via Bot API\n- **15. Google Sheets \u2014 Log Digest** appends the digest summary to the Digest Log tab\n- **16. Google Sheets \u2014 Mark Videos Processed** updates each Video Queue row with Processed status\n\n## Set up steps\n1. In **4. WayinVideo \u2014 Submit Summarization** and **6. WayinVideo \u2014 Get Summary Results** \u2014 replace `YOUR_WAYINVIDEO_API_KEY`\n2. In **12. OpenAI \u2014 GPT-4o-mini Model** \u2014 connect your OpenAI credential\n3. In **2** and **15** and **16** \u2014 connect Google Sheets OAuth2 and replace `YOUR_TREND_SHEET_ID`\n4. In **14. Telegram \u2014 Send Daily Digest** \u2014 replace `YOUR_TELEGRAM_CHAT_ID` and connect your Telegram Bot credential (create bot via @BotFather, get chat ID via getUpdates)\n5. Create a Google Sheet named TikTok Trend Tracker with two tabs: Video Queue (columns: Video URL, Video Title, Niche / Category, Date Added, Status, Processed Date) and Digest Log (columns: Digest Date, Niche, Videos Processed, Overview, Top Patterns, Action Recommendations, Top Tags, Telegram Sent, Sent On)" }, "typeVersion": 1 }, { "id": "91cd6804-d1fa-458f-9c57-92f8e366ce36", "name": "Section \u2014 Schedule Trigger", "type": "n8n-nodes-base.stickyNote", "position": [ -3872, 64 ], "parameters": { "color": 5, "width": 260, "height": 324, "content": "## Schedule Trigger\nFires every day at 8AM automatically.
