This workflow fetches the channel’s message history and lets you ask natural-language questions (“what were the decisions?”, “who’s blocked?”, “summarize yesterday”). The assistant **only** answers from the channel’s actual messages—no guessing.\n\n---\n\n## ⚙️ Setup Instructions\n\n### 1️⃣ Set Up OpenAI Connection\n1. Go to [OpenAI Platform](https://platform.openai.com/api-keys) \n2. Navigate to [OpenAI Billing](https://platform.openai.com/settings/organization/billing/overview) \n3. Add funds to your billing account \n4. Copy your API key into the **OpenAI credentials** in n8n\n\n### 2️⃣ Connect Slack API\n1. Create an app → <https://api.slack.com/apps> \n2. **OAuth & Permissions** → add scopes you need to read channel history (typical: \n `channels:history`, `groups:history`, `im:history`, `mpim:history`, plus `channels:read`, `groups:read`, `users:read`. Add `chat:write` if you want the bot to reply in Slack.) \n3. **Install** the app to your workspace → copy the **Bot User OAuth Token** \n4. In n8n → **Credentials → New → Slack OAuth2 API** → paste token and save \n5. In the **Slack History** node, select your Slack credential and the **Channel ID** to read\n\n---\n\n## 🗣️ Example Questions You Can Ask\n- “Give me a 5-bullet summary of the last 24 hours.” \n- “What action items were assigned, and to whom?” \n- “List open questions that haven’t been answered yet.” \n- “Who was mentioned most this week?” \n- “Summarize decisions from the last sprint planning.” \n- “Show messages with the word ‘blocker’ from the past 2 days.” \n- “What files/links were shared today?”\n\n---\n\n## 📬 Contact\nNeed help customizing this or adding auto-replies back into Slack?\n\n- 📧 **robert@ynteractive.com** \n- 🔗 **[Robert Breen](https://www.linkedin.com/in/robert-breen-29429625/)** \n- 🌐 **[ynteractive.com](https://ynteractive.com)**\n", "workflow": { "meta": { "instanceId": "ad0113c344ee237399e44e9f11798b05baeb83a6196d514a9ae9d2ad71c3b5c9", "templateCredsSetupCompleted": true }, "nodes": [ { "id": "e2c58c94-6864-431d-a5e3-56ea2757cf10", "name": "Slack Channel Chatbot", "type": "@n8n/n8n-nodes-langchain.agent", "position": [ 192, -1328 ], "parameters": { "options": { "systemMessage": "You are a helpful assistant.
