The Pay Tray App has a set of settings for each integration.
Settings Set Per User
All settings in the CP Pay Tray App are scoped to each user’s windows profile. This means that when a user logs in to Windows for the first time after the CP Pay Tray App has been installed, they will need to configure their settings.
If you switch between Windows profiles, the settings, and the tray app will reflect the user who is using the computer.
