Margin Issue while squaring off existing position via API's

I have been trading via API’s for more than a month now and it was working fine. Today, i faced one issue.
I had an open position(purchased yesterday- 31/07/2023) in option(FINNIFTY 01 AUG 20350 CALL), But when placing SELL order around 15:05 today (01/08/2023)via API the order failed asking for more margin which should not be the case as i am squaring off my position. Can you please investigate as it could derail my trading strategies.
