GST verification API
Confirm any GSTIN is valid, registered, and actively filing — with legal name, address, GSTR filing history, and e-invoicing status returned in a single real-time API call.
How GSTIN verification works
1. Send the GSTIN
Call GET /api/get-taxpayer-info/{gstin} with your API key in the x-api-key header.
2. Query live GST records
The API checks the GSTIN against live government records, not a cached or third-party copy.
3. Get a structured result
A JSON response returns legal name, status, address, filing history, and e-invoicing status — in one call.
Understanding GSTIN status
Every verification result includes a status field. Here's what each value means in practice:
The GSTIN is currently registered and in good standing.
GST registration has been cancelled — the business should not be treated as compliant.
Registration is temporarily suspended, often pending a compliance review.
