11st Open API (11번가) on a Mac

11st marketplace seller API · E-Commerce

11st (11번가) sellers get a 32-character Open API key in the OPEN API CENTER (openapi.11st.co.kr > API 관리) after logging in with the seller account. Seller-tool access permissions and allowed source IPs are configured on the same page. Seller APIs are XML over http(s)://api.11st.co.kr/rest/..., and responses are EUC-KR encoded. Since 2026-06-30 keys have a 180-day validity. Renewal opens 60 days before expiry, keeps the same key value, and expired keys stop all product, order and stock integration.
