Employee Directory Contact Automation using Qualtrics file service

Hi Team,

I want to import directory contact details from SAP Success Factors using Qualtrics File Service. Does this require any API coding and API tool like POSTMAN or can we directly do this through Success Factors? Can we push the import file from SAP Success Factor to Qualtrics HTTPS endpoint. Please advice. ( I have gone through the contents in Support portal for this automation)

Regards,
Satheesh
