Understanding skuType and skuTypeId

In the /api/v4/product/ endpoint, the skuType field identifies the type of SKU associated with a product.

skuType A string value that describes the SKU type.

Currently, the only expected value is "regular".

skuTypeId A numeric identifier that corresponds to the skuType.

1 → "regular"

2 → (reserved for future SKU types)

If both skuType and skuTypeId are present, their values should be consistent with each other.
