Unlock system users via the API

Navigate to the Administraion and then the API reference guide. 
Under "user" in the API reference there is an API call for "Get a paginated list of users" 
Set Domain ID (this is typically 1)
Toggle "Includesystem" to true
Toggle "IncludeDisabled" to true 
You may need to increase page size or search for a specific user but this is not required. 
Click Try it out 




The response body should return a list of users. 


You would collect the username that is locked and then navigate to  "Unlock a user account that was locked due to too many invalid/failed login attempts" under the User API header. 



Input the domain Id and the user id and click try it out. This should reset the system user account.
