We received a notice from you about the changes to the customs declaration category, see below.

When I go the the Products page as suggested, I can see there are two new categories: Commercial Sale of Goods (B2B) and E-commerce Goods (B2C).

When I look at the current specification, it is still version 1.0.0.
In the customsDeclarationCategory field, these are missing.
Now, I wonder how to set these fields and if they are required.

API: https://api.parcel.royalmail.com/
API spec: https://api.parcel.royalmail.com/doc/v1/click-and-drop-api-v1.yaml

Could you please update your API specification to reflect the changes?
If you cannot do that, please let me know what the new values are that are accepted.

----------------- Royal Mail message below -----------------

We recently notified you about a legislative change affecting item
declaration categories.

As part of this change, the 'Sale of goods' and 'Mixed' declaration
categories will soon no longer be valid. Using either of these
categories will prevent your orders from being processed, so any
products in your catalogue currently assigned to them will need to be
updated before this takes effect.

To help you do this, we have added a migration tool to the Products
page:
https://business.parcel.royalmail.com/products

This tool will also update your default customs package contents
declaration category if it is currently set to 'Sale of goods' or
'Mixed'. If your product declaration categories already meet the
updated requirements, the tool will not be displayed.
