Frequently Asked Questions
Everything you need to know about the GST Advance Verification API.
1. What makes the "Advance" version different from basic GST verification?
While basic verification only confirms the GSTIN's existence, the Advance API provides deep business intelligence including GSTR-1 and 3B filing trends, taxpayer constitution, jurisdiction details, and an algorithmic compliance score.
2. How current is the GST filing data provided?
Our API performs real-time queries against the GSTN database. You receive the exact filing status as of the moment the request is made, ensuring zero lag in your compliance audits or vendor risk assessments.
3. Can I use this API for automated vendor onboarding?
Yes. The API is designed for programmatic integration. It returns structured JSON which can be used to auto-populate master data records, verify trade names, and automatically approve or flag vendors based on their filing history.
4. Does the API provide Principal Place of Business addresses?
Yes, the response includes the complete registered address, including the principal place of business and any additional places of business registered under that specific GSTIN.
5. Is it possible to detect "Cancelled" or "Suspended" GSTINs?
Absolutely. The API returns the exact current status of the taxpayer (Active, Cancelled, Suspended, or Provisonal) along with the date of cancellation where applicable.
6. Does the API support checking multiple GSTINs at once?
While standard requests are per-GSTIN, our enterprise infrastructure supports high-volume concurrent processing. For bulk audits, you can iterate through our high-speed endpoints with minimal overhead.

The Advance API tracks the filing status of GSTR-1 (Outward Supplies) and GSTR-3B (Summary Return), providing the return period, date of filing, and mode of filing for the last 10-15 periods.
9. What is the success rate of the API?
We maintain a >99% API success rate. Our system includes automatic retry logic and intelligent caching for jurisdictional data to provide a seamless experience even during peak government portal traffic.
