Sale Request - Pre-Authorize Supplement

It is possible to increase the pre-authorized amount of a sale by using a pre-authorized supplement. It works as a referenced payment to a completed and existing pre-authorized transaction, requiring its id and authorization code.

Note that you can increase the pre-authorization amount with several supplements, and apply a reversal to each one of them, but the pre-authorized amount can never exceed the total amount of the sale (so if you need to increase the sale's total amount, you will have to use the Modify Sale functionality).

Also, if you need to reverse a pre-authorization, you'll need to make sure all its supplements are reversed. On the other hand, refunding a pre-authorization will refund all its supplements automatically.
