3 Whenever external learning content is integrated into a course via the** LTI tool **course element, the learning platform transfers information to the external tool when the LTI link is used. This data transfer enables the tool to clearly identify the course, the participant, and the respective situation of use.
4
5 Apart from anonymous context information, you can specify which additional information should be sent to the LTI tool in the **Parameters** tab of the LTI Tool course element.

7 {{info}}
8 Exact data transfer depends on the LTI settings in the course and the requirements of the integrated tool. Check the [[Data and parameters transfer via LTI>>doc:LMS.Benutzerhandbuch OPAL.Lehren.Kursbausteine.LTI-Tool.Daten- und Parameterübertragung über LTI.WebHome]] page for general information on data transfer to an LTI tool.

The result of the entered expert rule is transferred to the LTI tool as a string. The **Preview button (5)** offers a test evaluation.

57 Which key-value parameters can be transferred depends on the connected LTI tool and should be documented there.
