Dhan API Integration

Lesson Content

The Dhan API provides developers with robust tools to build algorithmic trading systems for the Indian stock market. To integrate Dhan's API, begin by creating an account and generating your API credentials. The API uses REST architecture with JSON data format, requiring proper authentication through API keys and secret keys. For implementation, use Python with the 'requests' library to send HTTP requests to Dhan's endpoints. Key functionalities include placing equity orders, managing positions, retrieving market data, and accessing account details. When placing orders, ensure proper validation of parameters like exchange (NSE/BSE), tradingsymbol, quantity, and transaction type. Error handling is crucial - implement checks for insufficient funds, invalid symbols, and market status conditions. For advanced users, consider implementing webhook handlers for real-time order updates and market data streams. Always use HTTPS for secure communication and store credentials securely, never hardcoding them in your scripts. Test thoroughly in the sandbox environment before deploying with real capital.
