Payload attributes issues

Hello,
As per Github, for placing order the code starts with order_id = kite.place_order(....etc)
if order_id is a variable so I can put any name instead of order_id? or should i give order_id for placing orders (buy and sell, SL order?

Example: I am using for first buying buy_order_id and selling sell_order_id, then stop loss stoploss_order_id. I noticed that sometimes sell and stop loss orders fail to place. I have tried all other ways to solve it. The issues come from these variables.
