Amount (in cents) to clear. Typically this will match the amount in the original authorization, but can be higher or lower. The sign of this amount will automatically match the sign of the original authorization's amount. For example, entering 100 in this field will result in a -100 amount in the transaction, if the original authorization is a credit authorization.

If amount is not set, the full amount of the transaction will be cleared. Transactions that have already cleared, either partially or fully, cannot be cleared again using this endpoint.
