Score supplier reliability from incidents with Claude, Google Sheets, and SendGrid

Description

Quick overview
This workflow receives supplier incident reports via webhook, uses Anthropic Claude to classify the incident and generate a recommendation, calculates an explainable reliability score, logs every incident to Google Sheets, and escalates high-risk suppliers by sending emails through SendGrid.

How it works
Receives a POST webhook request containing a supplier incident report and recent performance metrics.
Uses Anthropic Claude to extract structured incident details such as severity, root cause, SLA breach status, and a short summary.
Routes low-confidence or unclear reports to a “Needs Manual Review” webhook response instead of scoring them.
Calculates an updated 0–100 supplier reliability score and tier using a rule-based formula that applies severity, SLA, root-cause, and incident-rate penalties.
Uses Anthropic Claude to generate a procurement-focused recommendation, reasoning, and corrective actions based on the incident and updated score.
Appends a scorecard row for the incident to a Google Sheets SupplierScorecard tracker via the Google Sheets API.
Sends escalation and supplier-improvement emails via SendGrid when the tier is At Risk/Critical or the recommendation is Probation/Terminate, then responds to the webhook with either an escalated or routine JSON result.

Setup
Add Anthropic credentials for the two Claude chat model steps.
Configure Google Sheets OAuth2 credentials and replace YOUR_SHEET_ID and the target range (SupplierScorecard tab) used by the Google Sheets API append request.
Add your SendGrid API key by replacing YOUR_SENDGRID_API_KEY in both email requests and set the “from”/recipient email addresses (including [email protected] and [email protected]).
Activate the workflow and copy the webhook URL into your incident source system so it can POST incident payloads to /supplier-incident-inbound.
