# Transmission

> Send signed invoices to NRS

## Purpose

Transmission sends a signed invoice to NRS for fiscalization. Use this step after you sign or after you sign and transmit in a single call.

## Options

* `POST /api/v1/einvoice/sign-transmit` signs and transmits in one request.
* `GET /api/v1/einvoice/transmit/{IRN}` transmits a previously signed invoice.

## After transmission

Use lookup and invoice retrieval endpoints to confirm status and access the stored record.
