How to create Shared Interview Schedule?

Hi All,

I understand that creating a Shared Interview Schedule is a prerequisite for triggering automated interview invitations to candidates. The Shared Interview Schedule allows candidates to view the interviewer's availability and book an interview slot.

I also understand that a recruiter can create a Shared Interview Schedule on behalf of an interviewer.

My question is: Is there any supported way to bulk create Shared Interview Schedules, such as through HDL, REST APIs, Spreadsheet Loader, or any other mass upload mechanism? We are looking for an option to avoid having each interviewer create their Shared Interview Schedule individually.

Has anyone implemented this successfully, or is manual creation the only supported approach?
