1.1 About this document
This document specifies the Sipajak API surface — the complete set of endpoints exposed for integration with partner and customer systems. It is intended for developers integrating Sipajak's tax-compliance services into their own platforms — typically backend engineers building connectors from an ERP, accounting platform, or master-data system.
The API surface is organised into six functional modules: Organization (profile and NPWP registration), VSWP (taxpayer validation), e-Faktur (VAT invoices), e-Bupot (withholding tax receipts), SPT (tax returns), and e-Billing (payment-code issuance). Sections 4 through 9 of this document cover each module in turn. The conventions established in section 3 (response envelope, authentication, soft-error pattern, date formats) apply across all modules and should be read once before working with any of them.
This is version 1.8 of the document. All module sections are now fully specified: Section 4 (Organization), 5 (VSWP), 6 (e-Faktur), 7 (e-Bupot), 8 (SPT), and 9 (e-Billing). The cross-cutting material (sections 1–3, 10–11) is complete and stable.

1.3 Module overview
The API surface is organised into six functional modules. Sections 4 through 9 cover each module in detail; the table below offers an at-a-glance summary.
| Module | Purpose | Section |
|---|---|---|
| Organization | Client profile, usage, history, and NPWP registration. The entry point for any new integration. | 4 |
| VSWP | Taxpayer-status validation (NPWP / NIK lookup against DJP Coretax CTAS). | 5 |
| e-Faktur | VAT invoice lifecycle: create, replace, cancel, return — for output and input invoices, including equivalent documents. | 6 |
| e-Bupot | Withholding-tax receipts (Bukti Potong) across all DJP variants. | 7 |
| SPT | Tax-return submission with seven-step lifecycle ending in DJP BPE acknowledgement. | 8 |
| e-Billing | DJP payment-code issuance for tax-payable amounts. | 9 |
1.4 Document conventions
Throughout this document:
- JSON path notation (e.g.
body.data.status) refers to the JSON Pointer–equivalent location in a request or response payload. - Path templates enclose path parameters in braces, e.g.
/v1/vswp/{id}. - Placeholder values in examples (such as
1234567890123000) are synthetic — they are valid in shape but do not correspond to real taxpayers.
