Seller API overview
The Seller API lets verified LoLBoost sellers manage listings and orders programmatically instead of doing everything by hand in the Seller Area. It’s built for sellers who run their own stock systems and want LoLBoost to stay in sync automatically.Who it’s for
You need an approved, active LoLBoost seller account before you can use the API. If you’re not selling on LoLBoost yet, start with Start selling first.What you can do
Manage offers
Create, update, list, and remove account and item offers from your own system.
Bulk stock updates
Remove many offers at once when stock changes outside LoLBoost.
Keep accounts and items in sync
Map your internal IDs to LoLBoost listings with
external_id.React to events
Get notified the moment an offer sells, so your own stock updates instantly.
