You can use this endpoint to reverse a pre-loan amount due to a confirmed reversal event by the network to the processor. Moreover, the amount of the reversal is subtracted from the pre-loan or transaction amount by MO. If the remaining pre-loan amount is less than or equal to zero, MO does not reject the transaction. Instead, it waits for either a rejection or settlement from the processor.
