It seems to me that authorize.net has lost sight of what is important and what isn't. Developers have been begging for important improvements for some time, with few tangible results. Instead of improvements such as exposing the expiration date in the CIM API, the ability to customize the CIM hosted form, or a token and ajax method we get more videos and JSON.
JSON certainly has some advantages over XML, but it doesn't give us any function we didn't have before. They are both text, presumably anyone who can write and parse one can write and parse the other.
Videos have their place, but I don't think it's here. Do we really want someone who can't read and understand the written word programming something that handles people's credit card data?
Both the videos and JSON are symptoms of the root problem, authorize.net's development seems to emphasize appearance, not function.
