Can I get started with HR WORKS straight away?

Theoretically yes, if you have your own HR WORKS instance, you only need a simple configuration in clock:it.
Once you have activated clock:it for HR WORKS, you must enter the field name for the transponder number in the settings.
The name for this has been created on the HR WORKS side under “Free fields”. In our standard system, we use “Transpondernummer” or for our English customers "Transpondernumber".

If you have the correct field name, go to clock:it Administration under Basic settings -> Settings. In the tree structure there is the entry HR Systems-> HR WORKS -> CardIdFieldName.
You can change the value here using the Edit button (or as seen in the Screenshot "Bearbeiten"). Enter the field name from HR WORKS here. Confirm by saving.

Important: After you have set the setting, you must restart the AppService.
