Transport request intake webhook with field validation

How it works

1. 1.A Webhook node accepts POST requests at transport-intake-lite and waits for a downstream response node.
2. 2.Normalize Fields trims the string fields and parses weight_kg, replacing comma decimal separators with dots.
3. 3.Validate Required Fields builds a missing_fields array and sets status to ready or needs_review.
4. 4.Build Result assembles a normalized_request object alongside status and missing_fields.
5. 5.Respond to Webhook returns HTTP 200 with a Content-Type application/json header.

Use cases

• Pre-screening transport requests before they enter operational systems.
• A lightweight validation endpoint for an external form or app submitting transport jobs.
• Normalizing request payload shape before storage or handoff to another workflow.

Requirements

• Activate the workflow in n8n so the webhook can receive requests.
• Send pickup_postcode, delivery_postcode, pickup_date, and weight_kg in the JSON body.
• No credentials are needed since all nodes are local operations.

Setup and testing in n8n

1. POST a request with all valid fields and verify the response status is ready.
2. POST with a non-numeric weight_kg and confirm it appears in missing_fields and weight_kg is null.
3. POST with empty fields and check status is needs_review with the correct missing_fields list.
