IRN Generation FAQ
What buyers ask.
What if the GSP relay fails?
Auto-retry with exponential backoff. The invoice draft is preserved; the IRN call retries until the GSP and IRP both respond. Idempotency keys prevent duplicate IRNs on retry. Status is visible on the invoice.
Is the local schema validation strict?
Yes. The GSTN schema is enforced fully before any GSP call. Common errors (bad GSTIN format, missing HSN, wrong place of supply, tax mismatch) are caught locally with field-level error messages, so most rejections never reach the GSP.
Multi-IRP. Why does it matter?
The GSTN has designated multiple IRPs for redundancy. If the primary NIC IRP is unavailable, the system can route to a secondary IRP without invoice intervention. This is why broker-led integrations are slower; we are integrated as an authorised GSP and route directly.
