Login flow

The login flow starts by navigating to the public Kite login endpoint.

https://kite.zerodha.com/connect/login?v=3&api_key=xxx

A successful login comes back with a request_token as a URL query parameter to the redirect URL registered on the developer console for that api_key. This request_token, along with a checksum (SHA-256 of api_key + request_token + api_secret) is POSTed to the token API to obtain an access_token, which is then used for signing all subsequent requests. In summary:

  1. Navigate to the Kite Connect login page with the api_key
  2. A successful login comes back with a request_token to the registered redirect URL
  3. POST the request_token and checksum (SHA-256 of api_key + request_token + api_secret) to /session/token
  4. Obtain the access_token and use that with all subsequent requests

An optional redirect_params param can be appended to public Kite login endpoint, that will be sent back to the redirect URL. The value is URL encoded query params string, eg: some=X&more=Y). eg: https://kite.zerodha.com/connect/login?v=3&api_key=xxx&redirect_params=some%3DX%26more%3DY

Here's a webinar that shows the login flow and other interactions.

Kite Connect handshake flow

Warning

Never expose your api_secret by embedding it in a mobile app or a client side application. Do not expose the access_token you obtain for a session to the public either.

type endpoint  
POST /session/token Authenticate and obtain the access_token after the login flow
GET /user/profile Retrieve the user profile
GET /user/margins/:segment Retrieve detailed funds and margin information
DELETE /session/token Logout and invalidate the API session and access_token

Authentication and token exchange

Once the request_token is obtained from the login flow, it should be POSTed to /session/token to complete the token exchange and retrieve the access_token.

curl https://api.kite.trade/session/token \
   -H "X-Kite-Version: 3" \
   -d "api_key=xxx" \
   -d "request_token=yyy" \
   -d "checksum=zzz"
