Automated Certification – Assessment System in n8n

Built an automated Assessment & Scoring Pipeline using n8n! 🚀 This workflow handles incoming assessment submissions, validates payloads, updates database records, and calculates average scores automatically: Webhook Endpoint: Listens for incoming POST requests ( /webhook-test/submit-assessment ) containing candidate submissions (e.g., quiz, practical, final project). Input Validation: Validates submission data integrity before execution continues. Database Operations: Saves assessment entries directly to Supabase ( Save Assessment ) and retrieves historical scores ( Get All Scores ). Data Transformation: Calculates total score averages dynamically across submitted assessments using a custom Code node. Progress Tracking: Updates overall candidate progress ( Update User Progress ) and returns structured JSON confirmation responses back to Postman/client. Eliminates manual grading and score tracking.
