The accept.js integration uses the Customer Information Manager (CIM) to store card details for reuse.
The API documentation for that is here https://developer.authorize.net/api/reference/index.html#customer-profil...
It appears there are no special fields beyond what is already being sent by the module.
This email appears to be notifying customers that they need to be using either ARB or CIM for stored payment details to be compliant.
I cannot find any information about these supposed "new API fields" mentioned.
