@webseos Thanks for your simple and effective answer. This works really well.

@admin How long the session created by the API call api.generateSession(config.clientId, config.password) is valid? Does the API give any notification/event when the session expires? I am developing a a trading software that will continuously run as a service and I would like to know how the session is managed. If the session expiry is based on a time interval, I want to invalidate the current session and create a new one before the expiry interval. Please help!

@Mnagesh That is awesome. In short, setting all price values to float and quantity values to int will work. It is very logical and according to JSON spec. Thanks for your prompt and very accurate reply.

@admin I am a proficient Python/REST API programmer. When I try to use api.placeOrder(orderParams)
with the following parameters, I am getting the exception "string indices must be integers" intermittently.
I have seen a resolution in another thread suggesting to use all parameter values as string. I followed the same. Still I am getting the exception. For the sake of completeness, I am setting all 15 parameters. Please help me to resolve the issue ASAP as it is blocking me. Here is the set of parameters that I am using:

{
"variety": "NORMAL",
"tradingsymbol": "MARUTI30JUN22FUT",
"symboltoken": "56863",
"transactiontype": "BUY",
"exchange": "NFO",
"ordertype": "MARKET",
"producttype": "CARRYFORWARD",
"duration": "DAY",
"price": "0",
"quantity": "100",
"triggerprice": "0",
"squareoff": "0",
"stoploss": "0",
"disclosedquantity": "0",
"ordertag": "api-order"
}

I installed SmartAPI with the command "pip install smartapi-python" without giving any version number.

@Bharath-Raj-M Did you get this problem solved? I am facing the same issue and it is very intermittent.
If this is solved. can you please let me know how?
