Quick overview

This workflow receives an RFx completion webhook, scores suppliers against cost, risk, lead time, and rating constraints, generates award scenarios, and uses Groq (LangChain agent) to produce a structured procurement recommendation, then stores results in Notion and posts success or failure alerts to Slack.

How it works

  1. Receives an HTTP POST webhook with an RFx ID, a suppliers array, and optional evaluation constraints.
  2. Validates that at least one supplier is provided, and if not, posts an error to Slack and returns an “invalid input” webhook response.
  3. Filters and scores suppliers using weighted cost, risk, lead time, and rating factors, then selects three scenarios (best cost, lowest risk, and balanced) and returns a ranked supplier list.
  4. Sends the scenario data to a Groq-hosted LLM via a LangChain agent to generate a JSON-only executive summary, insights, trade-off analysis, and a final recommendation.
  5. Parses and validates the AI JSON output, and if it fails, posts an error to Slack and returns an “AI error” webhook response.
  6. Stores the recommendation and insights in a Notion database, posts a completion message to a Slack channel, and returns a success response to the original webhook request.

Setup

  1. Copy the webhook URL from the Webhook trigger and configure your RFx system to POST rfx_id, suppliers[] (with cost, risk, lead_time, rating), and optional constraints to that endpoint.
  2. Add Groq API credentials for the LangChain Groq Chat Model used by the AI analysis step.
  3. Add Notion credentials and select the target database, ensuring it has properties for RFx ID, Best Supplier, Executive Summary, Cost Insight, Risk Insight, Trade-off, and Final Recommendation.
  4. Add Slack credentials and set the target channel for both success and failure notifications.
  5. Review and adjust the scoring weights and constraint defaults in the supplier scoring logic to match your award criteria.

Troubleshooting Guide

Issue Possible Cause Solution
No suppliers processed Empty suppliers array Ensure suppliers are passed correctly
Workflow stops early Validation failure Check webhook payload
Incorrect scoring Missing supplier fields Ensure cost, risk, lead_time, rating exist
AI output invalid Improper JSON response Adjust AI prompt formatting
Slack not sending messages Invalid credentials Reconnect Slack API
Notion not saving data Wrong database mapping Verify database fields
API returns error AI validation failed Check AI output node
Unexpected results Constraints too strict Relax constraints
