If the wrong split has been sent you can cancel it through Payaut’s API with an empty request body.
Splits can be cancelled whilest they have not yet been reconciled. Once reconciled, further investigation by the Payaut support team is needed to cancel a split payment.
There are several reasons for cancelling a split e.g. if they payment was not completed or if the wrong split information was sent e.g. the wrong distribution of funds.
