GSTIN API is a REST-based interface for real-time verification of Goods and Services Tax Identification Numbers in India. The software provides instant access to taxpayer details, including legal business names, addresses, registration dates, taxpayer status, return-filing history, and e-invoicing activation through a single endpoint. Designed for ease of use, the API delivers predictable JSON responses and supports integration in JavaScript, PHP, and Python. The platform enables single or bulk GSTIN lookups, streamlining vendor validation processes. Security features include TLS encryption and API key authentication, ensuring secure data transmission. With direct integration to official GST data, the software delivers instantaneous results, avoiding delays from cached or batch-processed systems.
