Indian Tax API
Pre-release · FreeMicrosoft's standard Business Central APIs carry no India GST fields and cannot be extended, so every Indian integration rebuilds the same layer. Indian Tax API is that missing layer, built once: GST-aware REST/OData endpoints for master data and documents, with GST computed by Business Central itself. Free, open source and pre-release / early access.
- GST fields (GSTIN, HSN/SAC, place of supply, reverse charge) as first-class, writable API fields
- Customers, Vendors, Items, Locations, Sales and Purchase documents with lines
- Document actions: Release, Ship & Invoice, Receive & Invoice, Post
- Posted invoices with GST amounts, e-invoice IRN and bill of entry
- AI-ready: works with the built-in Business Central MCP server
