DATEV Online APIs (Sandbox)

DATEV Online APIs (Sandbox)

Sandbox environment for the DATEV Online APIs — read accounting Mandanten (clients), document types and DUO version metadata against DATEV's test data. Use this while you build and test; every new DATEV app must run in sandbox until DATEV grants production approval. Same OAuth2 Authorization Code + PKCE flow as production, pointed at DATEV's sandbox endpoints.

Configurar DATEV Online APIs (Sandbox)

Directamente de la definición del conector: dónde encontrar las credenciales, qué permisos necesitan y con qué API habla este adaptador. Proporcionadas en inglés por el autor del conector.

Use this connector for testing. Every DATEV app runs in the sandbox until DATEV completes its production-approval review — so this is where you start.

Setup:

  1. Create a Confidential app on the DATEV-Entwicklerportal (https://developer.datev.de) with OpenID Connect Authorization Code Flow. Set the redirect URI to <your-server>/api/mcp-oauth/callback.
  2. Subscribe the app to the sandbox API products: accounting:clients 2.0 and accounting:documents 2.0.
  3. Set DATEV_CLIENT_ID and DATEV_CLIENT_SECRET (from the portal — copy the secret in full, it is shown only once).
  4. Import this adapter — it is pre-configured for the sandbox (authorize login.datev.de/openidsandbox/authorize, token sandbox-api.datev.de/token, API base platform-sandbox/v2) and authenticates at the token endpoint via HTTP Basic (client_secret_basic), which DATEV requires.
  5. Run the one-time OAuth flow: POST /api/connectors/{id}/oauth/authorize -> open the returned URL -> log in with your DATEV-Konto -> the platform stores an encrypted refresh token automatically.
  6. Every call then sends Authorization: Bearer <token> AND the mandatory X-DATEV-Client-Id: <DATEV_CLIENT_ID> header automatically.

Going to production: once DATEV approves your app for production, use the separate DATEV Online APIs connector (same credentials, production endpoints).

Scopes requested: datev:accounting:clients accounting:clients:read accounting:documents. Do NOT add openid — it is the issuer name, not a requested scope.

Mandant scoping: every per-client tool takes a clientId parameter — the Mandant UUID (RFC4122), returned by datev_list_clients. Distinct from DATEV_CLIENT_ID (the OAuth app identifier, sent in the header).
