inFlow Concepts

Entity IDs vs Names

Most resources accept either a GUID entity ID or a name. The node automatically detects which format you're using.

Include Parameters

When fetching products or orders, you can include related data:

• cost - Product cost information
• defaultPrice - Default selling price
• inventoryLines - Stock levels by location
• vendorItems - Vendor-specific product info

Smart Filter

The smart filter searches across multiple fields (name, SKU, barcode) to find matching records.

Error Handling

The node provides detailed error messages from the inFlow API:

Code	Description
400	Bad Request - Invalid parameters
401	Unauthorized - Invalid API key
404	Not Found - Resource doesn't exist
409	Conflict - Duplicate entry
422	Unprocessable - Validation failed

Security Best Practices

1. Protect API Keys: Store credentials securely using n8n's credential system
2. Limit Permissions: Use API keys with minimum required access
3. Audit Access: Regularly review API key usage in inFlow
4. Use HTTPS: All API calls use HTTPS encryption

Development

# Install dependencies
npm install

# Build
npm run build

# Run tests
