Request MAC Key Class Diagram

Requesting a new MAC Key involves the Merchant authenticating themselves as in the previous example. At this point, there are two possible scenarios:

  1. This is an existing merchant who is renewing their MAC generation key. In this case, the merchant must also supply their last key to verify their identity.
  2. There is no existing MAC Key for a new merchant. A new MAC generation key will be generated without any additional authentication criteria.
