Taxpayer Authentication

Taxpayer Authentication establishes a secure authenticated session to fetch, save, reconcile and file GSTRs. Authentication is a necessary step to transact with the GST Network. Once authenticated, a session is created through which a taxpayer can fetch details, file returns, and reconcile using Taxpayer APIs.

3. In the 'Quick Links' section, go to 'Manage API Access'
4. Set 'Enable API Request' to 'Yes'
