cppkiteconnect

Unofficial headers only c++ client for communicating with the Kite Connect API.

It is based on official zerodha dotnetkiteconnect.

Kite Connect is a set of REST-like APIs that expose many capabilities required to build a complete investment and trading platform. Execute orders in real time, manage user portfolio, stream live market data (WebSockets), and more, with the simple HTTP API collection.

Documentation

• Kite Connect HTTP API documentation

Requirements

• GCC 4.9.x (std::regex supported) or Visual Studio 2017 / 2015 update 3 (on windows): c++11 compliant compiler.

Dependent Libraries

• fmt : A modern formatting library.
• Boost : boost-regex (csv parsing) & boost-log Logging ( I have used boost 1.67 ). I plan to remove boost & fmt for spdlog and std::regex for csv-parser.
• CPR : C++ Requests.
• nlohmann-json : C++11 headers only json parser.

All these can be added (sourced & compiled ) wrt your platform by using Microsoft vcpkg. You must give it a try. Note i have build this code only on windows machine, but it should compile on Linux

Installation Using vcpkg

On Windows:

• Install git
• Install Visual Studio 2017
• Install vcpkg Remember that in this (vcpkg) dir all the libraries will be built, so this drive should have sufficient space.
• Open command prompt or powershell prompt and change dir to vcpkg dir
• Install dependent libraries : vcpkg.exe install cpr fmt nlohmann-json boost
• Git clone or download cppKiteConnect.
• Start a new C++ project in Visual Studio
• Open example directory and build

On Linux:

• Install git
• Install latest gcc.
  • CentOs
    • yum install devtoolset-7-gcc* libstdc++-static glibc-static
    • scl enable devtoolset-7 bash
  • Ubuntu
    • https://gist.github.com/jlblancoc/99521194aba975286c80f93e47966dc5
• Install dependent libraries
  • CentOs
    • yum install curl fmt boost
    • nlohmann-json : need to clone and install.
    • CPR : need to compile and install.
    • cppKiteConnect : clone git, use the header files present in include.
  • Ubuntu
    • sudo apt-get install curl fmt boost nlohmann-json-dev
    • CPR : need to compile and install.
    • cppKiteConnect : clone git, use the header files present in include.
