Returns one adjustment with its header, its lines and its attributes.

Ask by RecVue's adjustmentId or by the externalId the caller sent. At least one is required; when both are sent, adjustmentId decides.

An adjustment belonging to another tenant is reported as not found.

Reading the answer: every response carries statusCode in the body, and that is the status to act on. The service returns it as the HTTP status too, but the gateway in front of these APIs currently answers 200 for refusals and leaves the real code in the body - the same behaviour raised for another endpoint in CS-41997. Read statusCode from the body and you are correct either way.
