Hi @deecha_87,

Buy Feed V1 API is currently unavailable in eBay's sandbox environment. Use of the APIs in production is restricted. See Production eligibility requirements in the Buying Integration Guide for more information.

And getItemFeed call can be used to download a TSV_GZIP file of the items in top-level (L1) categories for a specific marketplace. You can refer to the "Retrieve a gzip feed file" guide for more details.
