GST Advanced API
Enhanced GSTIN verification with compliance and filing history, promoter details, turnover data and e-invoice applicability for deeper KYB checks.
What the GST Advanced API does
GST Advanced goes beyond confirming a registration exists. It returns the business details together with compliance history, promoter and director information, turnover bands and whether e-invoicing applies.
Filing behaviour is the signal that matters most here. A business that files consistently looks very different from one with long gaps, and that difference is directly relevant to credit decisions and to your own input tax credit risk.
Where teams use the GST Advanced API
Assessing a business borrower's compliance behaviour
Estimating turnover band for credit limits
Identifying promoters behind a merchant entity
Checking e-invoice applicability before transacting
Frequently Asked Questions (FAQs)
What does filing history reveal?
Consistency. Regular filings suggest an operating, organised business; extended gaps suggest distress or dormancy and warrant caution.
How precise is the turnover data?
It is reported in bands rather than exact figures, which is enough for segmentation and credit limits.
Why does e-invoice applicability matter?
Businesses above the threshold must issue e-invoices. If a supplier should be doing so and is not, their invoices may not support your input tax credit.
