🔗 Slack + Bitly UTM Generator — Powered by OpenAI
Description:
This no-code n8n workflow transforms how marketing teams generate Bitly links with UTM parameters — directly from Slack. Powered by AI and fully automated, this system extracts relevant campaign data from a Slack message, creates a clean Bitly shortlink with UTM tags, and logs everything to a Google Sheet for tracking and reporting.
Perfect for growth marketers, content teams, and anyone tired of manually building UTM-tagged links.

⚙️ How It Works
🟢 Slack Trigger
The workflow starts when a user mentions the bot in a Slack channel (e.g., @BitlyBot link this for IG campaign).
🧠 AI Agent (LangChain)
Uses GPT-4o-mini to infer UTM values (e.g., utm_source, utm_medium, utm_campaign)
Normalizes short forms like "IG" to "instagram"
Follows UTM naming conventions (e.g., lowercase, underscore-separated)
🔍 Information Extractor
Pulls cleanly structured UTM data from the AI response to prep for Bitly.
🔗 Bitly Tool Node
Generates a short link using the inferred target URL + UTM values.
📋 Google Sheets Logger
Automatically appends the full details (Bitly link, UTM parameters, campaign owner) to a Google Sheet for easy access.
📢 Slack Response
Replies in-thread with the new Bitly link and campaign details, formatted clearly for the user.
🛑 Error Handling
If Bitly link generation fails, the workflow gracefully stops with an error message.
