The Partner API provides a set of hardcoded test accounts in the test environment. Each account is pinned to a single point in the order and contract lifecycle, so you can build and verify your integration against every state — including error and edge cases — without submitting real orders or triggering any grid operation processes. For every test account, the customer number and contract number are identical and include the state suffix (for example D0000004_Delivery). Pass the full value, suffix and all, wherever an endpoint expects a customerNumber or contractNumber.
Test accounts return deterministic, synthetic data. They exist only in the test environment (test-api.rabot-charge.de) and never appear in production.

​
Available Accounts

Each account maps to one order state and its corresponding delivery state. The Scenario column describes what the account is designed to help you test.
For GET /partner/v1/orders and GET /partner/v1/orders/{contractNumber}, the Scenario text above is returned in the response-envelope message field, so you can confirm which account you are hitting. The /contracts, /metrics, and dayaheadworkingprice endpoints keep their own message semantics.

​
Supported Endpoints

The test accounts resolve on the following read endpoints:
Test orders are only returned from GET /partner/v1/orders/:contractNumber when you explicitly filter by a test account’s contract number. They never appear in unfiltered order lists, so they won’t pollute your normal integration flows.

​
Behaviour Notes

​
Null delivery state

For D0000001_Open and D0000002_Processing, the order has been exported but no delivery state has been reported yet. On these accounts the entire deliveryState object is null — not just deliveryState.state. Handle the object being absent, not merely a null inner field.

​
End of delivery

endDateOfDelivery is only populated for D0000006_Cancelled (2026-09-30). All other accounts return null.

​
Quick Start

Fetch the happy-path contract to confirm your credentials and base URL are wired up correctly:
From there, swap the account in the path to walk through each order state your integration needs to handle — D0000007_Rejected for the denial path, D0000006_Cancelled for terminations, D0000009_Unspecified for defensive edge-case handling.
