Several clients extend the expiration date through API to show longevity of the credentialee. There is currently no way to send a "renewal" email. I was hoping since our system knows to charge a credit there must be some sort of trigger we could create so that when a credential is renewed via an extension of the expiration date an email could be sent to the recipient notifying them of the credentials renewal. This is also common for clients who allow their recipients to renew early.
