What is the WhiteBooks e-Invoice API?

A REST API that generates IRN (Invoice Reference Numbers) through the official IRP, supports cancellation within the 24-hour window, and exposes status / verification endpoints. WhiteBooks holds GSP certification, so the API uses the authorised government channel.

Can the API generate IRN in bulk?

Yes. Submit an array of invoices in a single request (up to 1,000 per call) and the API returns IRN + QR per invoice, with per-row error codes for any that failed validation.

How long does an IRN take to generate?

Typical end-to-end latency is 200–400 ms for a single-invoice request and 2–4 seconds for a 100-invoice batch. SLAs apply on enterprise plans.

What if the IRP is down?

WhiteBooks queues failed requests and retries automatically when the IRP comes back up. Webhook callbacks notify your system once each IRN is successfully generated.

How do I get sandbox credentials?
