This problem is born of JSDCLOUD-630: SSO integration with JIRA Service Desk.
We do currently have an internal endpoint which is called when resetting the customer password
However, this can only be run by copying the command from the browser dev-tools console to cURL. The drawback of this is the copied command is only valid for the life of that browser session.
Create an external endpoint for resetting JSD customer passwords to allow Jira Service Desk admins to have move options when managing customer accounts.
