Automated eDIS authorization for https://dhan.co/

This script streamlines the eDIS authorization process for https://dhan.co/ without the need for browser automation tools like Selenium. The primary advantage of this approach is its efficiency on small virtual machines, especially those with limited resources where running browsers like Google Chrome might be challenging due to high memory consumption.

Before integrating this script into your project, I recommend thorough testing to validate its functionality and to ensure compatibility with your specific use case. The script has been designed to automate the eDIS authorization flow exclusively through the API, eliminating the need for browser involvement.

1. Clone this repository to your local machine.
2. Navigate to the project directory and install all dependencies.
3. Customize the script if needed, and ensure it aligns with your project requirements.
4. Update the required environment variables:

   DHAN_ACCESS_TOKEN
   DHAN_CLIENT_ID
   DHAN_TPIN
   

5. This script requires permissions to read email for the authorization OTP. It assumes that the email is hosted on Gmail. Follow the Google's app setup guide mentioned on this page to get programmatic access to your Gmail account. When the script is executed for the first time, it will prompt you to authorize access to your Gmail account and download the credentials file. This setup is required only once.
6. Execute the script:

   python main.py

7. Monitor the output for any error messages or unexpected behavior.
