  description: The Groww Trading API is the official programmatic interface to the Groww investing and trading platform, enabling algorithmic trading, order management, portfolio and position tracking, margin calculation, live market data (LTP, quote, OHLC, option chain, greeks) and historical candle data across the CASH (equity) and FNO (derivatives) segments on Indian exchanges. Requests are authenticated with a daily access token (or an OAuth2 / API-key + secret / TOTP flow) and versioned with the X-API-VERSION header.
