Turn TallyPrime into a
Modern REST API.
Empower your developers. We wrap Tally's complex XML gateway in a secure, high-speed REST API so you can connect your mobile apps, custom portals, and SaaS tools effortlessly.
The Business Problems We Solve
Siloed Data: Field agents can't see live outstanding balances because Tally is stuck on an office LAN.
Developer Frustration: Your modern React/Node developers refuse to work with archaic Tally XML.
Security Risks: Exposing Tally's default port 9000 to the public internet is a massive security vulnerability.
Delayed Syncs: Relying on daily manual Excel exports means business decisions are always 24 hours behind.
How the Data Flows
A clear, secure, and automated data pipeline.
API Request
Your custom App sends a standard HTTP GET/POST request (e.g., fetch Customer Outstanding).
Secure Proxy
Our Node.js API Gateway authenticates the request via JWT and validates the parameters.
XML Fetch
The Gateway queries Tally locally via XML, ensuring maximum speed and security.
JSON Response
The XML is parsed back into a clean JSON array and returned to your App.
Standard vs. Custom Tally Integration
Limitations of Standard Tally
- • Tally does not have native API authentication (like Bearer Tokens or API Keys).
- • Tally cannot cache data. If 500 field agents query stock at once, Tally will freeze.
- • Tally's default XML response includes hundreds of unnecessary nodes, causing massive data payloads.
The Custom Integration Advantage
- We build a secure middleware layer with robust API Key and JWT authentication.
- We implement Redis caching so frequent queries (like Item Master lists) return in milliseconds without hitting Tally.
- Our API strips out Tally's bloat, returning only the clean, specific data points your app actually needs.

Tally API Integration FAQs
Technical and operational answers about integrating your systems with Tally.
Does TallyPrime have a built-in REST API?
No, Tally natively communicates via XML over HTTP. We build custom Node.js middleware to wrap Tally's XML interface into a clean, modern REST API (JSON) that your developers can easily consume.
Can my mobile app fetch live stock from Tally via API?
Yes. We expose an endpoint (e.g., /api/stock) that your mobile app can query. The middleware fetches the live data from Tally and returns it instantly to the app.
How do you secure the Tally API?
Our middleware acts as a secure proxy. We implement JWT authentication, IP whitelisting, and rate limiting so external apps never have direct access to your Tally server or internal network.
Can you trigger an API call FROM Tally to an external app?
Yes, using custom TDL (Tally Definition Language). For example, when a user saves a Sales Invoice in Tally, we can write a TDL script that fires an outbound webhook to your CRM instantly.
What is required on the server side for this API?
Tally needs to be running with the company open on a server. Alongside Tally, we deploy our lightweight middleware service (Node.js/Python) which handles the API routing and data translation.
Do you integrate Tally APIs with n8n or Zapier?
Absolutely. Once we expose the Tally data via standard REST endpoints, it can be seamlessly plugged into low-code automation tools like n8n, Make, or Zapier for limitless workflow automations.
