TSS API facility updated

If you submit large numbers of ENS declarations, you can automate the submission process through use of an API. 

Following a recent upgrade, the API will soon support the upload of simplified frontier declarations for controlled goods as well as supplementary declarations for standard goods.  

Guidance to support your development of an API can be found here. When you’re ready to start testing this new functionality please raise a case to access the test environment through the TSS Portal, as new credentials will be required. 

In the meantime, you can also use the GOV.UK Trade Tariff online tool to validate your inventory data, in preparation for making your declarations over the updated API.
