Set Config Node\n Edit the **Set Config** node with your values:\n - `product_name` — Your product name\n - `product_description` — Short description of your product\n - `upload_post_user` — Your Upload Post profile username\n - `upload_post_api_key` — Your Upload Post API key (from\n upload-post.com dashboard)\n - `spreadsheet_id` — Google Sheet ID (already set)\n\n ### 2. Google Sheet\n The sheet needs 2 tabs:\n - **Performance Log** — columns: `post_date, request_id,\n post_url, platform_post_id, title, description, strategy_notes,\n prompts_summary, views, likes, comments, shares, engagement_rate`\n - **Agent Skill** — columns: `id, skill_content, last_updated`\n - Copy to your drive this template and put the id : https://docs.google.com/spreadsheets/d/1jk1GvBd6b4DopVH1VXkIsY0yPoCmE-DsA9Kun0ZAfQU/edit?usp=sharing \n\n ### 3. Credentials Required\n - **Google Sheets OAuth2** — for reading/writing the sheet\n - **Google PaLM (Gemini)** — for the Strategy Agent (Gemini 2.5\n Pro)\n - **fal.ai (Header Auth)** — for image generation\n - **OpenAI** — for descriptions + skill updates (GPT-4.1)\n - **Upload Post** — for publishing to TikTok\n - **Upload Post (Header Auth)** — same API key, for analytics\n endpoints\n\n ### 4. How It Works\n Every run:\n 1. Reads all posts from the sheet\n 2. Fetches fresh TikTok stats for each post via Upload Post API\n 3. Updates stats in the sheet (views, likes, etc.)\n 4. Reads the Agent Skill file (accumulated learnings)\n 5. Gemini 2.5 Pro creates an optimized carousel strategy based on\n ALL past data + skill\n 6. Generates 4 images (9:16) with text via fal.ai\n 7. GPT-4.1 writes the TikTok description\n 8. Publishes to TikTok via Upload Post\n 9. Logs the new post to the sheet\n 10. GPT-4.1 analyzes all data and updates the skill file\n\n ### 5. First Run\n On the first run, the sheet is empty so the agent has no history.\n It will create a baseline post. From the 2nd run onwards, it\n starts learning and improving.", "height": 1100, "width": 744, "color": 5 }, "id": "8f742164-ac55-480c-842d-99ad108455f9", "name": "Note Setup1", "type": "n8n-nodes-base.stickyNote", "typeVersion": 1, "position": [ -1392, 112 ] } ], "pinData": {}, "connections": { "Daily Schedule": { "main": [ [ { "node": "Set Config", "type": "main", "index": 0 } ] ] }, "Set Config": { "main": [ [ { "node": "Read Performance Log", "type": "main", "index": 0 } ] ] }, "Read Performance Log": { "main": [ [ { "node": "Filter Posts for Stats", "type": "main", "index": 0 } ] ] }, "Filter Posts for Stats": { "main": [ [ { "node": "Get Post Analytics", "type": "main", "index": 0 } ] ] }, "Get Post Analytics": { "main": [ [ { "node": "Extract Stats", "type": "main", "index": 0 } ] ] }, "Extract Stats": { "main": [ [ { "node": "Update Stats", "type": "main", "index": 0 } ] ] }, "Update Stats": { "main": [ [ { "node": "Aggregate", "type": "main", "index": 0 } ] ] }, "Aggregate": { "main": [ [ { "node": "Get Profile Analytics", "type": "main", "index": 0 } ] ] }, "Get Profile Analytics": { "main": [ [ { "node": "Read Agent Skill", "type": "main", "index": 0 } ] ] }, "Read Agent Skill": { "main": [ [ { "node": "Read Fresh Data", "type": "main", "index": 0 } ] ] }, "Read Fresh Data": { "main": [ [ { "node": "Prepare Context", "type": "main", "index": 0 } ] ] }, "Gemini 2.5 Pro": { "ai_languageModel": [ [ { "node": "Strategy Agent", "type": "ai_languageModel", "index": 0 } ] ] }, "Think Tool": { "ai_tool": [ [ { "node": "Strategy Agent", "type": "ai_tool", "index": 0 } ] ] }, "Output Parser": { "ai_outputParser": [ [ { "node": "Strategy Agent", "type": "ai_outputParser", "index": 0 } ] ] }, "Prepare Context": { "main": [ [ { "node": "Strategy Agent", "type": "main", "index": 0 } ] ] }, "Strategy Agent": { "main": [ [ { "node": "Set Vars", "type": "main", "index": 0 } ] ] }, "Set Vars": { "main": [ [ { "node": "Generate Image 1", "type": "main", "index": 0 }, { "node": "Generate Image 2", "type": "main", "index": 0 }, { "node": "Generate Image 3", "type": "main", "index": 0 }, { "node": "Generate Image 4", "type": "main", "index": 0 } ] ] }, "Generate Image 1": { "main": [ [ { "node": "Extract URL 1", "type": "main", "index": 0 } ] ] }, "Extract URL 1": { "main": [ [ { "node": "Merge Images", "type": "main", "index": 0 } ] ] }, "Generate Image 2": { "main": [ [ { "node": "Extract URL 2", "type": "main", "index": 0 } ] ] }, "Extract URL 2": { "main": [ [ { "node": "Merge Images", "type": "main", "index": 1 } ] ] }, "Generate Image 3": { "main": [ [ { "node": "Extract URL 3", "type": "main", "index": 0 } ] ] }, "Extract URL 3": { "main": [ [ { "node": "Merge Images", "type": "main", "index": 2 } ] ] }, "Generate Image 4": { "main": [ [ { "node": "Extract URL 4", "type": "main", "index": 0 } ] ] }, "Extract URL 4": { "main": [ [ { "node": "Merge Images", "type": "main", "index": 3 } ] ] }, "Merge Images": { "main": [ [ { "node": "Aggregate Images", "type": "main", "index": 0 } ] ] }, "Aggregate Images": { "main": [ [ { "node": "Generate Description", "type": "main", "index": 0 } ] ] }, "Generate Description": { "main": [ [ { "node": "Upload to TikTok", "type": "main", "index": 0 } ] ] }, "Upload to TikTok": { "main": [ [ { "node": "Log to Sheets", "type": "main", "index": 0 } ] ] }, "Log to Sheets": { "main": [ [ { "node": "Update Skill", "type": "main", "index": 0 } ] ] }, "Update Skill": { "main": [ [ { "node": "Write Skill", "type": "main", "index": 0 } ] ] }, "When clicking ‘Execute workflow’": { "main": [ [ { "node": "Set Config", "type": "main", "index": 0 } ] ] } }, "active": false, "settings": { "executionOrder": "v1", "callerPolicy": "workflowsFromSameOwner", "availableInMCP": false }, "versionId": "1ce6e012-d178-4970-8785-008a6d6d5634", "meta": { "instanceId": "3378b0d68c3b7ebfc71b79896d94e1a044dec38e99a1160aed4e9c323910fbe2" }, "id": "GqeKzQgvF2M1wvNz", "tags": [] }
