Package Exports
- n8n-nodes-vh3ai
- n8n-nodes-vh3ai/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (n8n-nodes-vh3ai) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
n8n-nodes-vh3ai
Community node for n8n that integrates with the VH3 AI field service management platform.
This package provides a single unified node (VH3 AI) that combines both BigChange API operations and VH3 AI intelligence features under one credential type. Resources are clearly labelled "(BigChange)" or "(VH3 AI)" in the dropdown.
The node is marked usableAsTool: true so it can be called directly by n8n AI agents.
Installation
Self-hosted n8n
Go to Settings → Community Nodes, click Install, and enter:
n8n-nodes-vh3ain8n Cloud
Search for VH3 AI in the community nodes section.
Manual / Development
cd n8n-nodes-vh3ai
npm install
npm run build
npm link
mkdir -p ~/.n8n/custom && cd ~/.n8n/custom
npm init -y
npm link n8n-nodes-vh3ai
n8n startCredentials
The node uses the VH3 AI API credential type:
| Field | Description | Default |
|---|---|---|
| API Key | Your VH3 API key (issued by VH3 AI) | — |
| Company ID | Your tenant / company ID | — |
| Base URL | VH3 Connect gateway URL | https://api.vh3connect.io |
| FSI Base URL | VH3 Field Service Intelligence API | https://api.vh3connect.io/api:kP8T1CK7 |
All operations authenticate using the same API Key and Company ID credentials.

Key Features
Simplify switch — LLM-friendly for cost-saving and efficiency
Every BigChange read operation exposes a top-level Simplify boolean. When ON, the node sends compact=true and the API returns LLM-optimised payloads (empty values stripped, nested structures flattened, custom fields collapsed to a key→value dict).
The Search › Autocomplete operation also has a Simplify toggle (default ON). This is handled at the node layer — it strips null, empty string, and empty array fields from each result and its nested extra object before returning data. false and 0 are retained as meaningful values.
List Invoices / Quotes / Sales Opportunities / Purchase Orders — automatic 12-month fallback
BigChange's finance list endpoints reject requests with no filter or date range. When no filter is supplied, the node automatically scopes the query to the last 12 months.
Email operations — attachment support
Classify Email and Ingest Email support optional attachments via URL (server-side fetch) or binary data (base64-encoded upload).
Search operations — per-result unwrapping
All search operations return one n8n item per result (envelope unwrapped at the node layer).
Sentinels — proactive monitoring
Deterministic checks (no LLM cost) against your VH3 AI platform fee. Available sentinels include Engineer Performance Slip, FVF Rate Drop, Workload Imbalance, Site Deterioration, Repeat Failure Escalation, and more.
Architecture & Patterns
Parameter casing
The n8n UI uses camelCase field names. The handlers map these to the appropriate API parameter format before sending.
Response normalisation
- BigChange:
extractItems()unwraps the three known envelope shapes into a flat item array. - VH3 AI: semantic search and autocomplete responses are unwrapped to per-hit / per-result items.
Auto-pagination
List operations expose a Return All toggle. When ON, the node walks every page automatically (capped at 200 pages).
AI tool compatibility
The node sets usableAsTool: true. n8n auto-generates a Tool variant (VH3 AI Tool) which implements the supplyData() interface for LangChain agents.
Deployment & Hosting
| Model | Description |
|---|---|
| Managed Hosting by VH3 AI | VH3 deploys and hosts the n8n instance at {customer}.n8n.vh3.ai. Runs the standard n8n Docker image from Docker Hub with n8n-nodes-vh3ai installed as a community node on startup. Database and config managed via environment variables on DigitalOcean. |
| BYOI (Bring Your Own Instance) | Customer runs their own n8n (self-hosted or n8n Cloud), installs n8n-nodes-vh3ai via Community Nodes, and gives VH3 an API key for workflow support. |
Compatibility
- n8n version: 1.0+ (tested on 2.16.x; community-node tool usage requires n8n ≥ 1.62 with
usableAsToolenabled) - Node.js: 18.10+
