증명서 자동 신청 및 다운로드
hometax__certificate__apply_auto_downloadREQUIRES prior hometax__session__login call with same account_link_id. Apply for the 납세증명서 (national tax payment certificate) with the fixed default issuance options and download the issued PDF in one step. The application happens first, so this files an application with the NTS and a receipt record (cvaId + rcatNo) is created; there is no cancel action. Template and issuance options are not configurable on this tool (use hometax.certificate.apply.national_tax_payment for options). Call without confirm first to get a preview, show it to the user, then retry with confirm=true. Never set confirm=true on your own. Files: the document the institution issued, unchanged, as PDF, listed in artifacts[] of the result with a download_url that works for 15 minutes; each file is kept for 7 days. If a link has expired, call xdata__job__result with the job_id from the result for fresh links.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| confirm | No | Set true ONLY after showing the preview to the user and receiving their explicit approval. Omit it on the first call to obtain the preview. | |
| account_link_id | No | Account link ID (UUID v4). Optional — the server auto-resolves from your API key when omitted. Provide explicitly only when you have multiple certificates for the same provider. Each institution has a separate ID (Hometax != NHIS != NPS != FourInsure). |
