Purpose

Use the invoice endpoints to validate payloads, sign invoices, and retrieve stored invoices. PASCA expects a structured invoice document with supplier and customer parties, line items, totals, and tax information.
  1. Validate the invoice payload with POST /api/v1/einvoice/validate.
  2. Sign the invoice with POST /api/v1/einvoice/sign to generate the IRN.
  3. Use the IRN for transmission, updates, and retrieval.
