The Goods and Service Tax (GST) on July 18, 2024, notified regarding the New API Features of E-Invoice Interoperable services.
The following has been stated:
• Authentication token can be generated from any of the Portals – e-Invoice1, eInovice2, e-Waybill1 or e-Waybill2, and once generated the same token can be used to access services across portals. No need to generate separate token for einvoice1 and einvoice2 as it was before.
• At e-Invoice1 portal, you can access services of einvoice2 and vice versa. That is, IRNs generated at e-Invoice2 Portal will be available at e-Invoice1 for cancellation and ewaybill generation. Similarly, IRNs generated at e-Invoice1 will be available at eInvoice2.
• To access the services of einvoice2, namely ‘Get IRN’, ‘Cancel IRN’ and ‘Eway bill by IRN’ from einvoice1, the URL and end points are same as of einvoice1, an additional header parameter ‘irp’ with value ‘NIC2’ needs to be passed, which indicates that service requested is from e-Invoice2. Similarly ‘irp’ should be ‘NIC1’ to access these services of e-Invoice1 from e-Invoice2.
