New method for capturing authorizations: While Authorizations are created the same way as in v2.0, capturing that Authorization now looks more similar as creating a payment. The main advantages for this are:
Support for multiple partial captures: Availability depends on region, please contact your Technical Account Manager for more details.
You can now add an order_id to each individual Capture, meaning that you can add your own external reference to each of them. Previously only the Authorization had this feature.
Refunds are now applied to individual Captures, and not to the Authorization.
Request headers now need to include API version (eg: X-Version = 2.1). Learn more here.
