TallyPrime Voucher API Consulting

I’m extending my own e-commerce automation software and need expert guidance on TallyPrime 7.0’s Sales Voucher Creation API. The main objective is to pipe order data from my platform straight into Tally without manual entry, so I’d like to understand the best-practice workflow for “integration with external systems.”

Here’s what I’m after:
• A short remote session (or two) where you walk me through authentication, payload structure, and endpoint setup for creating sales vouchers in real time.
• Sample XML/JSON requests that match TallyPrime 7.0’s schema, plus clear notes on mapping common e-commerce fields (order ID, taxes, discounts, payment modes).
• Advice on handling duplicate checks, batching, and any error responses Tally might return so I can build reliable logging in my code.
• A concise write-up outlining the steps I should follow whenever Tally upgrades.

My side is already collecting orders; I just need your TDL / ODBC / REST expertise to bridge it cleanly into TallyPrime. If you have previous experience wiring custom platforms—or even Shopify, WooCommerce, or Magento—into Tally, that context will help, but the emphasis here is on a bespoke solution.

Deliverables are complete once I can push a test order from my software and see an accurate sales voucher appear in TallyPrime without errors.
