Why print APIs matter for ERP teams
After an invoice is signed and an IRN or E-way bill is generated on the GST network, operations teams still need the official PDF printouts for transport, archives, and customer portals. Pulling those PDFs through the same API key as signing keeps integrations simple.
E-way bill print
IG E-Sign can download detailed, regular, or consolidate E-way bill PDFs using a 12-digit e-way bill number. Calls run through your tenant account with the GSTIN and NIC portal credentials stored on your company profile.
- Detailed E-way bill print by e-way bill number
- Regular and consolidate print variants for common logistics workflows
- Binary PDF download or JSON with base64 for server-side ERP clients
E-invoice print (IRN)
For e-invoices, pass the 64-character Invoice Reference Number (IRN) to download the official e-invoice PDF. The same company profile and API key used for GSTIN lookups and signing apply — no separate product login for print.
Setup checklist
Complete your company profile, save encrypted NIC portal credentials, keep your account Active, and call the print endpoints from a trusted backend. Never embed API keys or NIC passwords in browser code.
