This API will allow you to reverse a payment to platform. The original external requestId (extRequestId) from the original payment to platform request is needed to match the original transaction.
The amount field is optional, some considerations:
If no amount is provided, it will attempt to reverse the entire value from the original extRequestId
If an amount is provided, it can be up to the entire amount of the original extRequestId (paymentToPlatform)
However, there is also tracking of the partial amounts that have previously been reversed. The partner cannot go over the original paymentToPlatform amount that was sent in increments of reversals.
