Common questions
Does Volanta Labs build eBay API integrations?
Yes. Volanta Labs built Packit, a multi-channel e-commerce operations platform that connects a seller's Amazon and eBay accounts through the eBay API and Amazon SP-API, keeping inventory, orders, shipping and channel data in sync in real time from a single dashboard.
Can you sync listings and inventory between eBay and Amazon?
Yes — that is precisely what Packit does. It keeps inventory, orders and shipping synchronised across both marketplaces, and charts revenue split by channel so a seller can compare Amazon against eBay performance directly. Synchronisation runs on a schedule as background jobs rather than inside the request cycle.
How do you stop eBay sync jobs from overlapping?
Packit runs marketplace synchronisation as scheduled Sidekiq jobs — orders every ten minutes, FBA quantities every fifteen, Buy Box prices every two hours, listings nightly — with a Redis lock preventing two sweeps from overlapping. Without that lock a long eBay pass stacking behind another would starve the worker, so a slow marketplace response delays a background job rather than a page load.
