FAQ
Does Niceggie AI Customer Service work with Best Buy Marketplace?
Yes. Authorizing your Best Buy store with its seller backend API key syncs buyer messages and orders into the workbench; no mailbox is needed.
Are Best Buy US and Best Buy Canada both supported?
Yes. Each site has its own seller backend and its own API key, so authorize each store with the key from its own site.
Why can't I see the API Key menu?
Only an administrator account in the Best Buy seller backend can view or generate the API key; sub-accounts don't see the menu.
Does the AI reply to Best Buy buyers automatically?
Not by default. The AI drafts and you confirm in the workbench before anything is sent. Auto-reply rules can answer recurring questions without you, under conditions you set: channel, store, inquiry type, buyer sentiment and hours.
