# Merchant confirmed a correction to the lottery incident

In order to prevent the introduction of coupons when they are not connected to the ability to collect coupons, causing problems in which the coupons cannot be collected, the correction of the voucher collection event needs to be confirmed before being connected.

This API must be called to turn on the voucher function before any other API, such as creating vouchers, can be called.

# Be careful

In order to prevent a correction conflict that results in a voucher receipt error, the final correction address is the address at which the correction was confirmed at the latest.
