DATEV Unternehmen Online is the cloud-based document exchange platform connecting German businesses with their tax advisors for accounting data exchange, document upload, and journal entry submission.

DATEV Unternehmen Online

Purpose: build and self-test before DATEV's technical review. Credentials: Apideck's temporary shared sandbox credentials, or your own DATEV app once it subscribes to an API product.

Obtaining production credentials from DATEV is a real, separate process gated by a passed technical review. Routing API calls to DATEV's production environment is not yet part of this connector's scope — sandbox is where builds and consumer connections currently run.
