Hi I'm using the CIM API, and am curious what kind of transaction I will be billed for. From my understanding, if I call and AUTH_ONLY and later a PRIOR_AUTH_CAPTURE I will be hit with two transaction charges from Authorize.net (Please correct me if I'm wrong). Will I also be charged for creating user profiles, adding payment profiles, getting transaction details, ect... ? Or will Authorize.net only bill me when authorizing a payment, and or capturing one. Thanks!
You are correct. In addition to the monthly $20.00 fee for using CIM, you are also charged if you perform a transaction that requires authorization or capture. In your specific example, there are two: one for Authorization Only and a second for Prior Authorization and Capture.
There are no fees for managing profiles using CIM, or obtaining data using the transaction details API.
