Car Accident Claims Triage Workflow: n8n + Sheets + Slack + Gemini

Car Accident Claims Triage in minutes—automated with n8n, Google Sheets, Slack, and Gemini

This n8n workflow automates the first stage of car accident claims triage: it collects claim details via an n8n form, checks the submitted policy in Google Sheets, detects potential AI-generated photo risk, generates field-visit instructions with Google Gemini, then dispatches the case to your team in Slack and logs everything back into Sheets.

What this workflow does

• Receives claim submissions through an n8n Form, including an uploaded photo (.jpg/.png).
• Validates policy status by looking up the submitted policy number in Google Sheets. If the policy is missing or inactive, it alerts a Slack channel and stops.
• Assesses photo authenticity risk by extracting image metadata and sending the uploaded photo to the Walterwrites image-detector API to estimate whether it is AI-generated.
• Routes for manual review when needed: the workflow scores image authenticity, categorizes it as suspicious, review, or likely authentic, and posts a Slack alert when manual review is recommended.
• Uses Google Gemini to triage the claim: with a LangChain agent, it decides whether a visit is required and generates priority, specialist type, tools needed, and a one-sentence technician brief.
• Dispatches and logs outcomes by sending a formatted dispatch request to Slack and appending/updating a Google Sheets dispatch log row with the claim details and AI assessment.

Use cases

• Insurance or claims teams that want faster first-response triage for incoming accident claims.
• SaaS operators building claim intake automation with policy validation and evidence risk scoring.
• Automation engineers deploying an n8n workflow for Slack-based dispatch with persistent audit logging in Sheets.
