what exactly response you're getting?

Hi Angel One Team,

We are currently encountering the following error while calling the ltp_data method:

{
    "timestamp": "2025-08-07T11:12:56.119578",
    "method": "ltp_data",
    "params": null,
    "response": {
        "success": false,
        "message": "Invalid Token",
        "errorCode": "AG8001",
        "data": ""
    },
    "error": null
}

The integration was functioning as expected until 1:00 PM today, and no changes have been made to our production environment.

Could you please investigate this issue at the earliest?

Best regards,
Roshan Grewal

Hi @rajanprabu

The code mentioned at:
https://github.com/angelbroking-github/smartapi-python

Does contain two parts:
Part 1:
Ordering through API

Part 2:
Ordering through Websockets

am I correct?

Hi Team / @admin

I am very new to using SmartAPI and would like to use Python library for placing orders. Can someone suggest steps to start using SmartAPI and provide the Difference between publisher | trading | market feeds API.

Thanks,
