<h1>GST Portal Introduces e-Invoice JSON Download Feature; Access via IRN or Period, Available for Six Months.</h1> The GST Network has launched a new e-Invoice JSON download feature on the GST Portal, allowing users to download generated and received e-Invoices in JSON format. Users can log in to the portal, navigate to the appropriate section, and search by Invoice Reference Number (IRN) or period to download individual or bulk e-Invoices. Downloads are available for up to six months from the IRN generation date and should be scheduled during off-peak hours to avoid system overload. The functionality is also accessible through GST Suvidha Providers via Government-to-Business APIs. A detailed manual and FAQ are available for guidance.
