e-Way Bill API for Tally Prime & ERP 9

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

The WhiteBooks Tally e-Way Bill TDL surfaces EWB actions on Tally Prime delivery/sales vouchers. Click "Generate EWB" after voucher save and the connector calls WhiteBooks API, writes the EWB number + validity back to the voucher, and supports Part-B update + extension as separate menu actions.

For multi-warehouse Tally setups, the connector picks up the source warehouse GSTIN automatically and routes EWB generation to the correct GSTIN account at NIC.
