Core concepts

PASCA uses a few key concepts throughout the API.
  • Invoice Reference Number (IRN): A unique identifier for each invoice. You use it to sign, transmit, and retrieve invoices.
  • Fiscalization: The process of transmitting a signed invoice to NRS for compliance validation.
  • Websign: PASCA signing workflow that produces a signed invoice and IRN.

​
Typical flow

  1. Validate your invoice payload.
  2. Sign the invoice to generate an IRN.
  3. Transmit the signed invoice for fiscalization.
  4. Check status or retrieve the invoice as needed.
