What is the e-Invoice API for Tally Prime & ERP 9?

The WhiteBooks Tally e-Invoice TDL surfaces IRN generation as a native action on Tally Prime invoice screens. Click "Generate IRN" after voucher save and the connector calls WhiteBooks API + writes IRN, signed QR, and signed JSON back to the Tally voucher for printing.

No external dashboard, no separate login — Tally users continue working in Tally and the e-Invoice compliance happens transparently. The TDL also supports bulk IRN for monthly billing runs (multi-voucher selection → bulk generate).

Frequently asked questions

Is cancellation supported from Tally?
