The CAE (electronic authorization code) is the number ARCA (ex AFIP) assigns to each electronic comprobante when authorizing it. It's what turns a PDF into a fiscally valid invoice: without a CAE, the comprobante doesn't exist for ARCA. Along with the CAE comes its expiry date and the QR that verifies it.
The classic way to get it is logging into ARCA with your clave fiscal and typing the comprobante by hand. The alternative is invoicing software connected to ARCA's web services that requests the CAE automatically when issuing.
FacturaHub does exactly that, with AI in front: say "invoice Company X $200,000" via WhatsApp, from Claude or the dashboard, and the system builds the comprobante, requests the CAE and returns the authorized invoice with its QR and fiscal PDF — in seconds.
All of it is free and unlimited: invoices, expenses, clients, CRM, POS with stock, reports and access via WhatsApp, web dashboard and Claude. No card, no expiry. The only thing measured is AI: 25 free actions per month, and if you need more you buy a one-time token pack that never expires.
It works through three synced channels: WhatsApp to solve things on the go, Claude to operate from your desktop in plain language, and the web dashboard for the full picture: charts, reports and exports. All three touch the same data in real time.
FacturaHub requests the CAE from ARCA when issuing. You never touch the clave fiscal site.
Every comprobante includes its QR for AFIP verification, as required.
If ARCA is unavailable, we save the pending comprobante and notify you to retry when it comes back.

The CAE has an expiry date tied to the comprobante's authorization. FacturaHub stores it with the comprobante.
No. The CAI was for printed invoice pads. The CAE is its equivalent for electronic comprobantes, today's norm.
