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