Introducing the Bolta API

Some links point to the service guide, which is in Korean.

Bolta provides RESTful APIs for issuing e-tax invoices and cash receipts, issuing documents, and looking up business registration status, bank account holders, revenue and expense records, and bank account transactions. Test keys prefixed with test_ let you test your integration without connecting to the National Tax Service (NTS).
