List categories
Requires an active API credential with the catalog:read permission. Lists the categories of products you can order now. Pass include_unavailable=true to also include the categories of out-of-stock and unavailable products, as the Products endpoint does with the same parameter; every category in the default list is still included. Sandbox credentials return the static sandbox category. Use the Products endpoint with a sandbox key to find scenario product IDs.
