    AB1010 - Invalid Session or Session Expired Please Re-Login

    Clients login their accounts in the morning but after 1 or 2 hr again they have to relogin.

    Due to this issue clients getting losses on live trading.


  • HI @PareshBhatiya

    The session generated through SmartAPI stays valid till 5 am of the subsequent day unless the user logs out. The session can expire in the following scenarios:

    1. We allow one active session per API key and per client id, so if a client tries to generate another session using same API key and client id, the earlier session will get expired.

    2. All sessions generated through SmartAPI will expire if the client resets his MPIN through Angel One mobile app or web.
