The Forced Authorization API is used to manually enter card numbers for authorization transactions when card information cannot be read. After calling this API, the forced authorization request will be pushed to the specified payment terminal, and the API returns immediately, indicating that the request has been successfully dispatched (does not mean the transaction is complete). The cashier manually enters the card number on the payment terminal, and the customer completes PIN entry and other operations on the payment terminal. Transaction results are obtained through asynchronous notification or active query.
