Mock

Mock. This operation is part of the approved contract but its module is not built yet. Run Core with N1_API_MODE=mock N1_DEV_AUTH=stub to get deterministic demo-shop data from it. The real server answers NOT_IMPLEMENTED until it ships; the schema and examples here will not change when it does.

Your id for this request (8–128 characters of A–Z a–z 0–9 . _ : -). Echoed back in the response header and in every error, so you can quote it when reporting a problem. Core makes one if you send none.
