sevdesk is a German cloud accounting, invoicing, and bookkeeping platform for freelancers and small businesses. Its RESTful API (base https://my.sevdesk.de/api/v1) exposes everything the web application does - contacts, invoices, orders, credit notes, vouchers (receipts), bank check accounts and transactions, parts (inventory), tags, plus DATEV and CSV exports - authenticated with a per-administrator API token passed in the Authorization header. Nested resources can be pulled in with the embed query parameter.
