Please note that the terminology and error codes used in the Card Issuing Sponsorship Guides differ from those found in the Newline Platform Overview Guides.

While both sets of documentation pertain to related services, they employ distinct naming conventions and error code formats. As such when referring to either guide, ensure that you are using the appropriate definitions and error codes specific to the guide in question to avoid any confusion or misapplication of information.
