Candis

Candis is a Berlin-based fintech (founded 2015) offering an AI-driven financial process automation and accounts-payable platform for SMEs. It captures incoming invoices, reads invoice data via OCR (business partner, amount, date, IBAN), routes them through approval workflows, and exports approved postings to accounting systems and ERPs. As a licensed DATEV interface partner it also integrates with Sage and Wolters Kluwer, and supports three-way matching of invoices against purchase orders and goods receipts. Candis exposes a public REST API (developer.candis.io) with an Export API, Core Data API, and read-only Invoice, Reimbursement Item, and Purchase Request Data APIs, secured with OAuth2/OIDC and fronted by an official MCP server.

Candis publishes 6 APIs on the APIs.io network, including Core Data API, Exports API, Invoices API, and 3 more. Tagged areas include Company, Fintech, Accounts Payable, Spend Management, and Invoice Management.

Candis’ developer surface includes documentation, API reference, getting-started guide, engineering blog, support, changelog, authentication, and 23 more developer resources.
