Getting started

A-CUBE API helps you handling the interaction with SDI (Sistema Di Interscambio) through simple REST APIs.

When you get onboard the A-CUBE API Platform you will receive:

This is the process to create and send a new invoice explained in few steps:

  1. Login into the platform to obtain a JWT token
  2. Create an invoice payload in JSON format
  3. The invoice payload is sent to POST /invoices
  4. The invoice payload is validated, translated into FatturaPA XML format and sent to the SDI
  5. Every notification from SDI will be dispatched in real time to the configured endpoints. All the notification will always be available using the notifications API
