Overview

Call POST /verification/v2/gst/get/{gst_in}/ from your backend with Authorization: Bearer <token>. Replace {gst_in} in the path with the 15-character GSTIN (URL-encode if your client requires it). The request body is typically empty unless OpenAPI lists fields for your tenant.

Key features

• Direct GSTIN pull when you already know the registration number.
• Pairs with PAN discovery: Use GST Details from PAN when you only hold PAN first.
