Open Sandbox for Developers

The API platform for high‑performance EN16931‑compliant e‑invoicing.

Our open sandbox gives you the fastest possible entry into automated document processes. At its core is the full‑featured obwyseAPI: your powerful interface for end‑to‑end EN16931‑compliant e‑invoicing — including validation, extraction, and visualization of incoming invoices, as well as creator functions for outbound processing. Complementary integrated services for archiving and partner management ensure that all relevant data remains secure, audit‑proof, and cleanly linked. With the Order‑X tool and the corresponding creator API, you can also generate standardized purchase orders and documents that integrate seamlessly into your e‑invoice workflows. One platform, three core functions, maximum integration freedom.
