Taxation API integration for GST, e-Invoice and e-Way Bill
Validate GSTINs, file and track returns through an authorised GSP, generate IRNs on the Invoice Registration Portal and raise e-Way Bills — GST compliance as an API.

Generate, update and cancel e-Way Bills for the movement of goods through the NIC EWB system.
GST compliance is not one integration, it is three systems with different owners. Return filing goes through the GSTN via an authorised GST Suvidha Provider. e-Invoicing is handled by the NIC Invoice Registration Portal, which issues the IRN and the signed QR code. e-Way Bills run on the NIC EWB system and are tied to the physical movement of goods. They share a taxpayer identity and almost nothing else.
Our taxation API integration presents all three through one consistent interface. GSTIN validation and return filing run through our authorised GSP gateway. IRN generation returns the signed QR payload ready to print on the invoice. e-Way Bills can be generated, updated and cancelled as consignments change. For finance teams this collapses a monthly reconciliation exercise into an automated step inside the billing system that already creates the invoice.
What you can build with taxation APIs
Invoice-time compliance
Generate the IRN and signed QR code at the moment the invoice is raised, so a compliant e-invoice is produced by the billing system rather than assembled later.
Automated return filing
Validate GSTINs on the counterparty master, prepare the return payload and file or track GSTR submissions through an authorised GSP without leaving your ERP.
Goods movement, documented
Raise an e-Way Bill when a shipment is booked, update it if the vehicle or route changes, and cancel it cleanly when an order is withdrawn.
Counterparty verification
Check a supplier or customer GSTIN and legal name before onboarding them, which is the cheapest available control against input-credit disputes later.

Frequently asked questions
Do we need our own GSP licence?
No. Return filing runs through Aeologic's authorised GST Suvidha Provider gateway, so you integrate against our endpoints rather than pursuing GSP accreditation.
Can e-Invoice and e-Way Bill be generated in one call?
They are separate systems and separate calls, but our connectors chain them so a single invoice event in your ERP can produce both the IRN and the corresponding e-Way Bill without a second workflow.
What happens when a GST scheme change lands?
Scheme and schema changes are absorbed by Aeologic as part of the engagement. Your integration contract stays stable while the upstream payload changes underneath it.
