I am using the Upstox API in my custom trading portal. I have generated an API key from my Upstox developer account and configured the redirect URI accordingly.
When I integrate the Upstox login flow in my application, it successfully redirects to the Upstox login page and works correctly for my own account (the one used to generate the API key).
However, the issue is that when another user (for example, my friend with a different Upstox account) tries to log in through my portal using the same API integration, the login does not work. It seems that only my own account can log in successfully, while other Upstox users cannot.
Could you please help me resolve this issue? I would like to allow multiple Upstox users to log in through my application using their own accounts via the same API integration.
Please let me know if any additional configuration or permission is required for this.
