Reverse Voucher to Cash

POST {api-url}/reverseClosure?ns={community}

Execute a reverse closure transaction based on a given voucher number. You can process a partial reversal; however, take note that the original voucher number will be regenerated if partial. Any amount up to the voucher’s total can be entered, and funds are reversed from the voucher’s balance.

If the voucher corresponds to a Voucher Type, the type will be dissolved, and the funds returned back to the merchant’s balance as cash.
