The Avalara Item Classification API provides the user with the capability to submit products for HS Classification and retrieve the HS Codes. There are two subscriptions available for the Item Classification API, With Storage and Without Storage.
Item Classification With Storage will automatically store your item metadata as an Avalara Item object. This allows easy reference of your Items and metadata throughout Avalara using your own SKU.
Item Classification Without Storage lets you store your classified items as best suits your needs. If you choose Item Classification Without Storage, you will need to create a webhook to receive your classifications.
