The sender of the XML message needs to have a Government Gateway account. Further information on how to obtain a Government Gateway account can be found on ATWD's Registering, enrolling and activating to use ATWD Service page.
If you are already registered on the Government Gateway and are enrolled to use the ATWD Service you will be eligible to use XML.
However, you will only be able to use XML provided you have the correct software installed.
Please note: It is the responsibility of the warehousekeeper or proprietor to arrange for XML software to be installed on their computer system.
