Generate multi-channel release notes from ClickUp tasks with GPT-4o, Notion & Slack

This workflow converts raw ClickUp task updates—received directly through a webhook—into fully automated release documentation. It validates incoming payloads, fetches and cleans task details, enriches them with AI-generated metadata, produces structured release notes using GPT-4o, publishes them to Notion, notifies stakeholders on Slack, emails a formatted summary, and logs the release into Google Sheets. The system handles malformed events gracefully by logging invalid payloads and continues only when a valid task_id is present. It extracts structured fields (title, description, links, priority, assignee), then augments them with AI-driven classifications such as risk level, change type, module, and impact score. GPT-4o generates polished release notes following a strict template. Finally, the workflow distributes the release across multiple channels while maintaining an auditable, centralized history.

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

🟢 Webhook — Receive ClickUp Task Update Captures incoming events from ClickUp via POST and forwards the raw body for parsing.

🧹 Code in JavaScript — Extract task_id Parses the raw webhook body and safely extracts task_id. Invalid JSON → forwarded to error logging.

🔍 Validate Incoming ClickUp Task Event Checks if task_id exists. Valid → continue workflow Invalid → log error to Google Sheets

📄 Fetch Full Task Details from ClickUp Retrieves full task metadata: title, description, status, priority, links, assignee details, and due date.

🧩 Extract Clean Task Fields from ClickUp Data Normalizes and structures the task fields into a clean, usable JSON object.

🧠 Provide GPT-4o Model for Metadata Extraction Loads the language model for metadata generation.

🔍 Generate Release Metadata via AI AI generates structured metadata including: • risk_level • change_type • module • impact_score • requires_testing

🧹 Parse AI Metadata JSON Output Parses stringified JSON from the AI node into valid structured JSON. Malformed metadata → returned as an error object.

🔀 Merge Task Details with Metadata Combines clean task fields with AI-generated metadata into a complete release-ready object.

🧠 Provide GPT-4o Model for Release Notes Supplies the language model needed to generate formal release notes.

✍️ Generate Structured Release Notes via AI Produces uniform release notes containing: • Summary • Improvements & Features • Bug Fixes • Impact Analysis • Known Issues

📝 Extract Release Notes Title & Final Output Extracts title from markdown and prepares final content for publishing.

📘 Create Release Notes Page in Notion Saves the release notes as a new page in the Notion Release Notes database.

💬 Post Release Announcement to Slack Sends formatted release notes + Notion link to the specified Slack user/channel.

📧 Send Release Summary Email Sends a structured HTML email with the release summary, full notes, and Notion link.

📊 Append Release Log Entry to Google Sheet Writes a complete release log entry including: • task ID • title • priority • module • risk level • Notion URL • Slack message URL • release date

🛑 Log Invalid ClickUp Events to Google Sheet Stores any invalid or incomplete webhook payload for debugging and auditing.
