E-Invoice API Reference

API reference for BigLedger’s Malaysia MyInvois (e-Invoice) module — the endpoints an integrator calls to submit, query, cancel and track e-invoices. The backend serves 855 e-invoice routes; these five pages document the 16 that the workflows below need, and every path on them is a row in the generated route table named in the front matter. The rest are rows in the same route table and will be rendered from it.

The operator’s view of the same workflows — screens, pools, month-end — is in the e-invoice guides and the sourced My E-Invoice Admin applet reference; this section keeps to the HTTP surface and links there rather than repeating them.
