Generate E-Invoice API
Generate a GST-compliant e-Invoice and receive the IRN, acknowledgement, signed invoice and QR code in one call, straight from your billing system.
What the Generate E-Invoice API does
Generate E-Invoice creates a GST-compliant electronic invoice and returns the Invoice Reference Number, acknowledgement details, the digitally signed invoice and its signed QR code.
Businesses above the turnover threshold must issue e-invoices, and an invoice without a valid IRN is not compliant. That has a direct consequence for the recipient: their input tax credit depends on it.

It carries the signed invoice details and allows verification of authenticity.
