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.
