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.

Inputs

  • Gstin
  • Consent artefact id

Returns

  • Basic details
  • HSN codes
  • Branch details
  • Filing history
  • Liability paid summary

POST /v1/gst/advanced
