API Only User Is Not Appearing When Creating a Service In [Admin > LaunchPoint]

[#1]

Issue Description
API Only user is not appearing when creating a service in [Admin > LaunchPoint]

Issue Resolution
It is highly likely that the reason why the API user was not appearing because it did not have "API Only" ticked. This can be checked in [Admin > Users & Roles > User > Edit User]. However, this cannot be modified once the API user is created, so in order for the API user to appear in LaunchPoint, "API Only" must be ticked when the API user is created.
