The [Invoicetronic API][2] is a RESTful service that allows you to send and receive invoices through the Italian [Servizio di Interscambio (SDI)][1], or Interchange Service. The API is designed to be simple and easy to use, abstracting away SDI complexity while providing complete control over the invoice send/receive process. It provides advanced features as encryption at rest, multi-language pre-flight invoice validation, multiple upload formats, webhooks, event logging, client SDKs, and CLI tools. For more information, see [Invoicetronic website][2] ## Before you start For the full integration guide, tutorials, SDKs and quickstarts, see the **[Documentation](https://invoicetronic.com/en/docs/)**. A few cross-cutting topics worth knowing before integrating: - **[Prerequisites](https://invoicetronic.com/en/docs/prerequisites/)** — what you need to start in Sandbox and what's required to move to production. - **[API Keys](https://invoicetronic.com/en/docs/apikeys/)** — how `ik_live_` and `ik_test_` keys select the environment. - **[Sandbox](https://invoicetronic.com/en/docs/sandbox/)** — free test environment that mirrors the live workflow, with no credits consumed. - **[Rate Limiting](https://invoicetronic.com/en/docs/ratelimiting/)** — per-second, per-minute and per-day limits; how to handle `429 Too Many Requests`. - **[Pagination](https://invoicetronic.com/en/docs/pagination/)** — `page` and `page_size` parameters and the `Invoicetronic-Total-Count` response header. - **[CORS](https://invoicetronic.com/en/docs/cors/)** — calling the API from the browser; allowed origins are configured per key. - **[Webhooks](https://invoicetronic.com/en/docs/webhooks/)** — real-time event notifications with HMAC-SHA256 signature validation. - **[Localization](https://invoicetronic.com/en/docs/accept-language/)** — use the `Accept-Language` header to receive error messages in Italian, English or German.
