Classify Developer Questions with GPT-4o from Slack to Notion & Airtable

📘 Description: This workflow automates the Developer Q&A Classification and Documentation process using Slack, Azure OpenAI GPT-4o, Notion, Airtable, and Google Sheets. Whenever a new message is posted in a specific Slack channel, the workflow automatically: Captures and validates the message data Uses GPT-4o (Azure OpenAI) to check if the question matches any existing internal FAQs Logs answered questions into Notion as new FAQ entries Sends unanswered ones to Airtable for human follow-up Records any workflow or API errors into Google Sheets This ensures that every developer query is instantly categorized, documented, and tracked, turning daily Slack discussions into a continuously improving knowledge base.

⚙️ What This Workflow Does (Step-by-Step)

🟢 Slack Channel Trigger – Developer Q&A Triggers the workflow whenever a new message is posted in a specific Slack channel. Captures message text, user ID, timestamp, and channel info.

🧩 Validate Slack Message Payload (IF Node) Ensures the incoming message payload contains valid user and text data. ✅ True Path → Continues to extract and process the message ❌ False Path → Logs error to Google Sheets

💻 Extract Question Metadata (JavaScript) Cleans and structures the Slack message into a standardized JSON format — removing unnecessary characters and preparing a clean “question object” for AI processing.

🧠 Classify Developer Question (AI) (Powered by Azure OpenAI GPT-4o) Uses GPT-4o to semantically compare the question with an internal FAQ dataset. If a match is found → Marks as answered and generates a canonical response If not → Flags it as unanswered

🧾 Parse AI JSON Output (Code Node) Converts GPT-4o’s text output into structured JSON so that workflow logic can reference fields like status, answer_quality, and canonical_answer.

⚖️ Check If Question Was Answered (IF Node) If status == "answered", the question is routed to Notion for documentation; otherwise, it’s logged in Airtable for review.

📘 Save Answered Question to Notion FAQ Creates a new Notion page under the “FAQ” database containing the question, AI’s canonical answer, and answer quality rating — automatically building a self-updating internal FAQ.

📋 Log Unanswered Question to Airtable Adds unresolved or new questions into Airtable for manual review by the developer support team. These records later feed back into the FAQ training loop.

🚨 Log Workflow Errors to Google Sheets Any missing payloads, parsing errors, or failed integrations are logged in Google Sheets (error log sheet) for transparent tracking and debugging.

🧩 Prerequisites: Slack API credentials (for message trigger) Azure OpenAI GPT-4o API credentials Notion API connection (for FAQ database) Airtable API credentials (for unresolved questions) Google Sheets OAuth connection (for error logging)

💡 Key Benefits: ✅ Automates Slack Q&A classification ✅ Builds and updates internal FAQs with zero manual input ✅ Ensures all developer queries are tracked ✅ Reduces redundant questions in Slack ✅ Maintains transparency with error logs

👥 Perfect For: Engineering or support teams using Slack for developer communication Organizations maintaining internal FAQs in Notion Teams wanting to automatically capture and reuse knowledge from real developer interactions
