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

- Enter

npm install n8n-nodes-work4allThen restart your n8n instance.
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.
