n8n-nodes-work4all

This is an n8n community node package that integrates work4all — the all-in-one ERP and CRM system — into your n8n workflows.

Features

• Create Incoming Invoices — post incoming invoices to work4all via GraphQL, with support for:
  • Form-field mode (fill each field individually)
  • JSON mode (pass a single JSON object — ideal for LLM output)
  • File attachments (PDFs, XMLs, ZIPs) via binary data from upstream nodes

Authentication

This node uses OAuth2 Client Credentials to authenticate against the work4all API.

You will need:

| Field | Description | |-------|-------------| | API URL | Base URL of your work4all instance, e.g. https://api.work4all.de | | Token URL | OAuth2 token endpoint, e.g. https://auth.work4all.de/connect/token | | Client ID | Your OAuth2 client ID | | Client Secret | Your OAuth2 client secret |

Contact your work4all administrator to obtain client credentials with the required permissions.

Installation

In n8n (recommended)

1. Go to Settings → Community Nodes
2. Click Install a community node
3. Enter n8n-nodes-work4all
4. Click Install

Manual (self-hosted)

Operations

Create Incoming Invoice

Creates a complete incoming invoice in work4all including line items and optional file attachments.

Supplier lookup — you can identify the supplier by (in priority order):

• Supplier Code (internal work4all ID)
• Supplier Name
• Customer Number at Supplier
• Supplier Contact Email
• Supplier IBAN

Invoice items — enter manually via form fields or provide a JSON array.

Attachments — attach files from binary properties of upstream nodes (e.g. HTTP Request, Gmail, Read Binary File). Supports form mode or JSON array mode for dynamic/LLM-driven attachment selection.

Example Workflows

The examples/createIncomingInvoice/ directory contains ready-to-import workflows:

| File | Description | |------|-------------| | w4a-invoice-gmail.json | Polls a Gmail inbox for invoice emails, extracts attachments, and creates incoming invoices in work4all | | w4a-invoice-exchange.json | Polls a Microsoft Exchange/Outlook inbox for invoice emails and creates incoming invoices in work4all |

To import: open n8n → Workflows → Import from file.
