Overview

What the GST Verification API does

GST Verification checks a GSTIN against India's Goods and Services Tax records and returns the essential registration details: legal and trade name, registered address, taxpayer type and current status.

This is the baseline check for onboarding any business customer. It confirms the entity exists, is registered, and matches the name it gave you, which is the minimum before extending credit or settling money.
