Sendbill (센드빌) on a Mac
Korean e-tax invoice API · Accounting & ERP
Sendbill is an e-tax invoice service run by Netmania. Its REST API covers certificate management, member management, tax invoice issue and query, Hometax integration, business suspension/closure lookup (휴폐업 조회) and extra email sending. There is no self-serve key: you submit the 도입문의 (adoption inquiry), and a development SBKEY plus a guide are sent by email. A production key follows after the move to production. Calls first exchange the SBKEY plus a business number for a JWT. Errors are returned with HTTP 200 and a negative Result value.
