lexoffice (rebranded to "lexware Office" in 2025) is a German cloud accounting, invoicing, and bookkeeping SaaS from Lexware (Haufe Group). Its public REST API lets developers push and pull business data - contacts, invoices, quotations, order confirmations, delivery notes, credit notes, dunnings, bookkeeping vouchers, files, payments, and profile metadata - and subscribe to webhooks via event subscriptions. Authentication is a self-serve Bearer API key. The API gateway moved from api.lexoffice.io to api.lexware.io on 26 May 2025 as part of the rebrand; the legacy host remained available through December 2025.
