In the Authentication section, select Anonymous and Use certificate from file:
Note: For the Certificate file location, the expected format is file.pfx pointing to the client certificate used by Qlik Sense. Do note that this is a filename and not a file location. The file system location of the file is determined by the CertificateDirectoryPath key in the Qlik REST connector config (C:\Program Files\Common Files\Qlik\Custom Data\QvRestConnector\QvRestConnector.exe.config). The default location where the Qlik REST connector will look for certificates is C:\ProgramData\Qlik\Sense\Engine\Certificates
This user will need to have the needed rights on the API endpoint. Using a RootAdmin account here is recommended.
Note: If using INTERNAL accounts, it is recommended to use the sa_api user rather than sa_repository. The sa_repository user is used by the Repository Service whereas the sa_api user is purpose built for use in API use cases. This allows better tracking through logs should you need to investigate what occurred on a system.
Test the connection and save it when it is successful.
