Hvor gemmer e-conomic momspercentage?

Hej alle!

Jeg er ved at lave et system hvor jeg kan oprette fakturaer lidt nemmere, uden hele tiden at logge ind i e-conomic (bare rolig, jeg har styr på sikkerheden!)

Jeg kan sagtens trække en liste med varer ud af e-conomic, via deres REST API.
Så får jeg følgende output (altså, jeg har fjernet alle varer undtagen den første, for ikke at fylde debatten unødigt):

Array

    [0] => stdClass Object
    (
        [collection] => Array
        (
            [0] => stdClass Object
            (
                [productNumber] => 1,
                [name] => 'Arbejdstime',
                [recommendedPrice] => 700,
                [salesPrice] => 700,
                [barred] => '',
                [lastUpdated] => '2022-05-19T13:22:00Z',
                [productGroup] => stdClass Object
                (
                    [productGroupNumber] => 3,
                    [name] => 'Ydelser m/moms',
                    [salesAccounts] => 'https://restapi.e-conomic.com/product-groups/3/sales-accounts',

                ),
                [pricing] => stdClass Object
                (
                    [currencySpecificSalesPrices] => 'https://restapi.e-conomic.com/products/1/pricing/currency-specific-sales-prices'
                ),
                [self] => 'https://restapi.e-conomic.com/products/1'
            )
        ),
        [pagination] => stdClass Object
        (
            [skipPages] => 0,
            [pageSize] => 1000,
            [maxPageSizeAllowed] => 1000,
            [results] => 70,
            [resultsWithoutFilter] => 70,
            [firstPage] => 'https://restapi.e-conomic.com/products/?skippages=0&pagesize=1000',
            [lastPage] => 'https://restapi.e-conomic.com/products/?skippages=0&pagesize=1000'
        ),
        [metaData] => stdClass Object
        (
            [create] => stdClass Object
            (
                [description] => 'Create a new product',
                [href] => 'https://restapi.e-conomic.com/products/?skippages=0&pagesize=1000',
                [httpMethod] => 'post'
            )
        ),
        [self] => 'https://restapi.e-conomic.com/products/?skippages=0&pagesize=1000'
    )
)

Jeg kan se i productGroup->name at det er en "'Ydelser m/moms"

Men hvordan ved e-conomic at det er 25% Moms? Eller er det hardcoded i e-conomic?
