REST API & DATEV Export — Automation for Professionals
Access your invoice data programmatically with the Werkzeu.ge REST API. The DATEV export generates posting batches in EXTF format that your tax advisor can import directly.
REST API
The API uses Bearer token authentication. Create API keys in the tool and use them in your automations:
- GET /api/v1/invoices — List all invoices
- GET /api/v1/invoices/:id — Get single invoice with line items
- GET /api/v1/invoices/datev-export — DATEV posting batch as CSV
DATEV Posting Batch
The DATEV export creates a posting batch in the standardized EXTF format (version 700). This can be imported into DATEV accounting software used by German tax advisors.
Who Is This For?
Freelancers and small businesses who want to automate their accounting. Export your invoices monthly or quarterly as a DATEV file and send it to your tax advisor — no more manual data entry.
