n8n Supplier Diversity Classifier: Groq + Notion + Slack Alerts

Automatically classify supplier diversity with Groq, save results in Notion, and alert your team on Slack

This n8n automation workflow takes a list of suppliers via webhook, uses Groq-hosted LLMs to classify each supplier’s diversity status and score, generates an alternative recommendation for low-diversity suppliers, then writes everything to Notion and notifies stakeholders through Gmail and Slack.

What this workflow does

• Receives supplier data via Webhook (POST): it exposes an endpoint (e.g., /supplier-onboarding) and expects a JSON body containing a suppliers array (fields like supplier_name, supplier_id, category, and country).
• Processes suppliers one-by-one: splits the incoming list into individual supplier records for classification.
• Classifies diversity with Groq LLM: labels each supplier as Minority Owned, Women Owned, Small Business, or Not Diverse, including a certification, a diversity score, and reasoning.
• Merges results back into the supplier record: adds the AI output plus a processing timestamp.
• Filters low-diversity suppliers: targets suppliers marked “Not Diverse” or with a diversity score below 50.
• Generates an alternative recommendation: for flagged suppliers, runs a second Groq LLM to produce a single standardized alternative supplier recommendation.
• Stores and alerts: creates a new page in a Notion database with supplier details and recommendation, then sends an alert email via Gmail and posts to a Slack channel before returning a JSON webhook response.

Use cases

• Supplier onboarding teams needing consistent supplier diversity classification during procurement workflows.
• SaaS operators and automation engineers building an auditable pipeline that logs decisions in Notion and escalates in Slack.
• Organizations periodically re-checking suppliers and requesting alternative options when scores are low.
