# Lexware Office — Accounting API: overview

> Canonical URL: https://developers.apideck.com/apis/accounting/lexware-office/overview

German SMB cloud accounting and invoicing platform by Haufe Group, formerly known as lexoffice.
- Status: beta
- Authentication: apiKey

- **partnership required:** false
- **partnership url:** https://www.lexware.de/partner/modelle/technologiepartner/
- **difficulty reason:** API key authentication — consumers create credentials manually
- **costs:** The public API requires the XL plan (€32.90/month, or €16.45/month introductory); no additional API fee.
- **webhooks:** Native — invoice, credit-note and contact (customer/supplier) change events; no bill events.
- **account type required:** Lexware Office XL plan — the tier that includes Public API access.
- **sandbox note:** Build against a free Lexware Office test account: all XL features for 30 days, unlimited accounts, no certification review.
- **apideck credentials note:** An API-key connector has no shared Apideck application to provide.
- **important to know:** Invoices and credit notes cannot be edited or deleted once created — the API has no update endpoint for either, at any status — so a document's status has to be right at creation. The connector attributes the invoice-deletion block to German GoBD record-keeping rules.
A Public API key is valid for at most 24 months, then deactivates and is deleted. The consumer has to extend it or mint a replacement before that date, or the connection stops working.
Payments has no equivalent resource on this connector — Lexware Office exposes only a voucher's payment-status summary, not a discrete payment record with a transaction date, amount or account reference.
Ledger accounts are read-only and list-only — there is no way to fetch, create, or modify an individual ledger account.

- **environment notes:**   - **environment:** Single environment
  - **description:** Lexware Office runs one environment (api.lexware.io). Testing and production use the same kind of credential — there are no separate development credentials to swap in later.
  - **environment:** Testing
  - **description:** Every call hits a live account and creates real business documents, so keep development on an account of its own rather than on a consumer's production data.
