We've been notified by DHL of the following problem with their sandbox system: > due to today's changeover of the sandbox environment for the Business Customer Shipping API to a new platform, there is currently some misbehaviour in the sandbox area. > > Among other things, this particularly affects some services that can no longer be accessed because the corresponding permissions are no longer available. > > Also, the use of the sender reference in the sandbox temporarily no longer works, so it is currently not possible to create labels via the sender reference or with a logo. > > All shipment numbers assigned by the sandbox currently end with the letter "C".
