About Maesn

Maesn is a Unified API for ERP and accounting integrations. Software teams build one integration to Maesn and connect to DATEV, SAP, Sage, Microsoft Dynamics 365, Exact Online, Lexware, sevdesk, Xero, Odoo, Fortnox and 30+ more systems through a single REST API. Maesn unifies authentication (API keys, OAuth, database credentials, 2FA), pagination and filtering, webhooks, logging, monitoring and error handling, and normalises responses into a common data model for invoices, journal entries, contacts, payments and more. Custom fields are mapped into one schema, and synthetic webhooks cover systems without native ones. SDKs, sandboxes and quickstarts are available for Python, JavaScript, PHP, Go, Ruby and Java. Integrations run white-label under your brand, including certified marketplace listings and an embedded auth flow. Maesn is built and hosted in Germany, ISO 27001 certified, GDPR compliant and DORA-ready, and processes API calls in real time without storing customer data.
