Dear Angel One Team,

I'm developing a trading platform that needs to integrate with Angel One's real-time data feed. After reviewing the WebSocket documentation (https://smartapi.angelbroking.com/docs/WebSocket2), I have some concerns about the implementation approach.

The current documentation suggests that a client code is required for WebSocket connections. However, as a platform provider, I need to:

1. Connect to real-time data feeds without individual client codes
2. Serve multiple users through a single platform connection
3. Maintain a scalable architecture for multiple concurrent users

Questions:

• Is there a separate API documentation for platform-level WebSocket integration?
• Do you provide a different authentication mechanism for platforms vs individual traders?
• What is the recommended approach for implementing real-time data feeds at a platform level?

I would greatly appreciate any clarification on the proper implementation path for trading platforms.

Thank you for your assistance.

Angel One SmartAPI User Login Flow Issue

Issue Description:
When integrating Angel One's SmartAPI user login (https://smartapi.angelone.in/publisher-login), we're encountering issues with the login response handling. The login window remains static after authentication, and we're unable to capture the response or redirect back to our application.

Current Behavior:

1. Login window opens successfully
2. User authenticates
3. Response is received (visible in Network tab):

json
{
"status": 302,
"url": "https://steadfastapp.in/angelone/redirect",
"data": {
"jwtToken": "...",
"refreshToken": "...",
"feedToken": "..."
}
}

4. But the window remains open and static

Attempted Solutions:

1. Direct response capture using MutationObserver
2. Response interception using injected scripts
3. Redirect URL handling

Request:

1. Please add support for localhost URLs during development (http://localhost:*)
2. Consider implementing a proper OAuth2 redirect flow similar to other brokers

Why localhost support matters:

• Essential for local development and testing
• Industry standard practice (used by Zerodha, Flattrade)
• Speeds up integration and reduces development time
• Helps in debugging and testing security implementations

Would appreciate guidance on the recommended way to handle the authentication flow during development. Thanks!

@Moderator_3 Why? how do you expect us to develop apps on SmartAPI if localhost cannot be used? is there way to overcome this?
