Zerodha API Login Flow


Type of Zerodha API

  1. Zerodha API for trading

    Zerodha offers different APIs to its users through Kite Connect to place, modify and cancel various order types like regular orders, after-market orders, cover orders, and GTT orders. It also has an API to retrieve user holdings and positions and calculate margin values. Currently, Zerodha does not have any API to integrate the back-office data.

    Zerodha API for Algo Trading

    There are various ways you can use Zerodha APIs to automate trading. You can convert your trading ideas into trading strategies using Zerodha APIs and build your own algorithmic trading system. The Kite Connect APIs are for trade execution. It does not offer you access to any technical indicators. The technical indicators are required to be created on your own. In case you plan to automate trading end-to-end, you are required to obtain the necessary exchange approvals to that effect.

    You can also use these Zerodha APIs to connect with third-party algo trading software like Amibroker to set up your trading strategies. All of these require coding skills and programming knowledge.

    Apart from this, Zerodha also offers Zerodha Streak that allows you to do algo trading without any coding knowledge requirement.

    It is important to note that an algo to perform well requires thorough back testing before implementing it to live.

  2. Zerodha WebSocket API

    Zerodha WebSocket API allows you to access 3,000 instruments across all exchanges on a single WebSocket connection and receive live quotes for them during market hours that include open, close, high, low, and market depth view for the top five orders. It also provides notifications for order updates in the form of text messages.

    To connect to Kite WebSocket API, you need an API key, access token, and a WebSocket client library in your choice of programming language. The access token gets generated once you enter the API key, API secret, and the request token. The request token is the token that gets generated on the registered redirect URL on successful login.

  3. Zerodha Historical data API

    The historical data API provides users with archived data for several years back in time. The data is available for all instruments across various exchanges and contains the timestamp, Open, High, Low, Close, Volume, and OI (open interest). The data is presented in the form of a candle and is available in several time intervals like 5 minutes, 15 minutes, hourly, daily, etc.

    The historical data is imperative for back testing purposes when one intends to do algo trading to give correct trading signals. The historical data API is available at Rs.2000 per month. It is important to note that you cannot subscribe to historical data API alone without a subscription to the live data as it is an add-on subscription to Kite connect.

  4. Zerodha Publisher API

    Kite Publisher API enables users to add buttons to their apps or websites that allow trade execution in one click. The publisher API is available for free and is beneficial for individuals who have their websites or apps related to stock market investments, research, advisory services that help people with investment decisions. The website visitors can click on the embedded buttons to place an order directly from there rather than leaving the website and logging into the Zerodha account separately to place the order.

    This feature is beneficial for both parties as it enhances the user experience and increases website traffic. You can add buttons for a specific stock or a basket with a maximum of 10 shares added to it. The buttons created can be either branded with the Kite logo, customized or dynamic.

  5. Zerodha Coin API

    Zerodha Coin APIs are the APIs built on the top of the BSE STAR MF platform that allows mutual fund investments. Zerodha Coin APIs enable individuals to buy, sell, and manage the SIPs of mutual funds listed on Zerodha's Coin platform. The orders for mutual funds do not get sent to the exchange immediately but in batches that run at frequent intervals. You can use the mutual fund APIs to place, modify, or cancel your orders. The APIs are also available to retrieve individual orders, entire order history for the last seven days, user portfolio, and instrument list.


Zerodha API example

You can use Zerodha API for different activities that can make trading easy and convenient for you as per your requirement. Let us see some of the simple examples of Zerodha API usage:

Example 1: If you wish to accumulate a certain quantity of a particular stock, you can schedule a daily program using Zerodha API to buy an 'X quantity of stock with price conditions/target that you may have in mind. With this, you need not place an order manually daily.

Example 2: You may want to know the margins for a bunch of stocks you intend to purchase. Currently, you use the margin calculators by keying in one-by-one stock details.

Span, Exposure, Option premium, Cash margin, VAR margin, etc.) for a list of orders in one go.
