Important Note :
1: Use the Outlet Login APIs to perform 2FA before initiating any AePS cash withdrawal transaction. For Outlet login API Click here.
2: Cash Withdrawal should be done within 3 minutes of 2FA
3: To determine whether a transaction is Onus or Ofus, check the isOnusTxn key in the response. If isOnusTxn is true, the transaction is Onus; if false, it is an Ofus transaction.
