Generate procurement knowledge base articles with Groq, Gmail, and Google Sheets

Description

Quick overview
This scheduled workflow pulls recent resolved procurement tickets and chat queries, clusters similar issues, and uses Groq LLMs to analyze patterns and draft Markdown knowledge base articles, then emails an approval request via Gmail and logs approved articles to Google Sheets.

How it works
Runs daily on a schedule and fetches the last 7 days of resolved procurement tickets and procurement-related chat queries via HTTP requests.
Normalizes both sources into a common issue format, clusters similar issues into procurement topics, and creates a short text summary for each cluster.
Uses Groq (Llama 3.3 70B) to generate a structured JSON analysis per cluster (problem, root cause, resolution, and title) and emails an alert via Gmail if the analysis output is empty.
Uses Groq to generate a full Markdown knowledge base article from the analysis and emails an alert via Gmail if the draft output is empty.
Detects the target audience (Employees, Suppliers, or Procurement Specialists) with Groq and rewrites the article to match the audience tone while preserving facts.
Emails an approval request via Gmail (send-and-wait), and if rejected routes the draft back for revision.
When approved, sends a publication notification via Gmail and appends the article content and basic metrics fields to a Google Sheets knowledge base log.

Setup
Add a Groq credential and ensure the Groq chat model (llama-3.3-70b-versatile) is available for the analysis, drafting, audience detection, and tone rewrite steps.
Connect a Gmail OAuth2 account and set the approval recipient(s) and notification recipients in the Gmail send-and-wait and notification email steps.
Connect Google Sheets credentials and update the target spreadsheet document ID and sheet/tab used to append published articles.
Replace the sample JSONPlaceholder HTTP endpoints with your ticketing system and chatbot query APIs, including any required authentication and query parameters.
Review the scheduled trigger time (currently 09:00) and adjust it to match your desired daily publishing cadence.

Troubleshooting Guide

| Issue | Possible Cause | Solution |
| ------------------------------------ | ---------------------------------------------------- | ------------------------------------------------------ |
| No tickets are retrieved | Incorrect API URL or authentication | Verify endpoint URL, credentials, and API permissions |
| Chat queries not appearing | Chat API returning unexpected data | Validate API response structure and mapping |
| Clustering produces poor results | Keyword rules do not match your business terminology | Expand clustering logic and add additional categories |
| AI analysis fails | Invalid Groq credentials or API issue | Verify Groq API key and model access |
| Empty issue analysis output | AI model returned blank response | Check prompts, Groq quota, and API availability |
| KB article generation fails | Model response failure | Review AI node execution logs |
| Audience detection incorrect | Article content lacks sufficient context | Adjust audience detection prompt |
| Approval email not received | Gmail OAuth issue or recipient error | Reconnect Gmail credentials and verify recipient email |
| Approval process stalls | Reviewer did not respond | Follow up manually or implement reminders |
| Articles not stored in Google Sheets | Incorrect Sheet configuration | Verify spreadsheet ID, sheet name, and column mapping |
| Duplicate articles generated | Similar issues appear in multiple clusters | Add duplicate detection logic before publishing |
| Revision loop repeats continuously | Reviewer continuously rejects content | Improve prompts and approval criteria |
