How to update Chrome driver?

(If you want to login immediately to place orders you can do manual login as mentioned here and update chromedriver after market hours)

For API login process, we have integrated Chrome automation through Selenium WebDriver and ChromeDriver.

Chrome automation will work only when Chrome and Chrome driver are having same version. This means whenever Chrome updated, you have to manually download the latest ChromeDriver and update in your system.

How to know 'When to update'

The Chrome login window doesn’t open OR open and closes instantly. You can check the WEBCONTROLLER logs to know the exact reason.
