GST Verification
Retrieve comprehensive GSTIN data across five sections — basic, HSN, branch, filing, and liability-paid.
Overview
What the GST Advanced API does
The GST Advanced API consolidates registry-grade GSTIN data into five sections: basic entity details, HSN codes traded, branch addresses, filing history, and liability-paid records. It gives underwriting and KYB teams a fuller view of a business's tax compliance than a standard GST check.
