DHL draws no distinction between a missing key and an\ninvalid one — both collapse into one generic refusal, unlike UPS/FedEx which at least\nkeep the error constant across a stable code (`250002` / `NOT.AUTHORIZED.ERROR`) that a\nclient could branch on; here even the vocabulary gives no signal about *why* access was\ndenied.\n\n## CORS/gateway fingerprint\n`access-control-allow-origin: https://developer.dhl.com` and\n`access-control-allow-headers` explicitly lists `DHL-API-Key` and `Correlation-Id` —\nconfirming the header name and that the API is meant to be called cross-origin from\nDHL's own developer portal UI. `x-request-id` and `correlation-id` are both minted\nper-request.
