n8n Workflow: Webhook Contract Renewal, Risk Scoring & Approvals

Automate contract renewal decisions with webhook intake, risk scoring, and approval routing in n8n

This n8n workflow exposes a /contract-lifecycle webhook that ingests contract details, calculates renewal urgency, calls external HTTP services for risk scoring and approval, and returns a complete lifecycle decision report—plus a request ID for auditability.

What this workflow does

• Receives contract data via POST webhook: Listens for incoming contract fields (e.g., title, vendor, value, endDate) and validates required inputs.
• Normalizes and prepares metadata: Ensures the incoming contract info is in a consistent format for downstream logic.
• Calculates renewal urgency: Computes days to contract expiry and flags whether renewal action is needed based on your configured renewal window.
• Calls external risk analysis: Sends contract context to an external HTTP risk endpoint, deriving a risk score and tier. If needed, it applies a fallback heuristic.
• Determines approval requirements: Chooses the required approval levels (or auto-approves) using contract value, risk tier, and renewal status.
• Submits to an external approval system: If not auto-approved, posts to an external HTTP approvals endpoint and interprets the result into a final lifecycle status.
• Returns a decision report via webhook response: Responds with status code, lifecycle outcome, audit details, and a request ID.

Use cases

• Contract operations teams need a consistent renewal process with risk-aware escalation.
• SaaS operators want webhook-driven contract lifecycle decisions integrated with external risk/approval services.
• Automation engineers need a clear, auditable workflow for renewal urgency, scoring, and approvals.

Technical details

• Nodes/tech stack: code, webhook, http request, wait, respond to webhook, sticky note.
• Webhook endpoint: POST to /contract-lifecycle.
• External integrations: Replace default risk and approval endpoint URLs (currently set to httpbin.org) with your real Risk Analysis and Approval System API endpoints.
