Hey @SamReganCC thanks for the request! Are you interested in this functionality for child users or referral customers? If not, this will not work via API to enable/disable/delete a parent user (normal user's) API keys.

@Justintime50 For referral customers. We are creating them via the API and need to delete/disable their API keys when needed. Thanks.
