September 21 certificate change with SHA-2

[Wayne]

I inherited an application that uses a post to https://secure.authorize.net/gateway/transact.dll to get payment authorization while out in the field.

All I know is the application is using c# .net and the users enter in the credit card info on the laptop and get the authorization using the post above.

I am trying to see if the new certificate changes will affect me and if so what I need to have my developers do. 

ANY help or guidance in this matter will be great.

thx

Hi Wayne,

As mentioned here the update was already completed on secure.authorize.net in May. The upcoming update is only referring to api.auth.net. If your application is working and uses secure.authorize.net, then you should be good to go.

Thanks,

Joy
