What authentication method does Workday use?

Workday uses OAuth 2.0 with a registered API Client. You'll need to provide your Client ID, Client Secret, and a Refresh Token — all generated from within your Workday tenant by an administrator.

Can I check PTO balances for my direct reports?

Yes. The `get_time_off_balances` tool retrieves current PTO balances for any worker within the security scope configured for your Integration System User. Data is returned per plan type (vacation, sick, personal).

Does it support Workday Report-as-a-Service (RaaS)?

Absolutely. Use the `execute_raas_report` tool with your report URL to retrieve any custom Workday report, including those with prompt parameters. Results are returned in JSON format.

Can I navigate the entire organizational hierarchy?

Yes. The `get_org_structure` tool fetches supervisory organizations, cost centers, and company hierarchies, allowing you to traverse the full org tree from any starting point.
