GET /caldav/calendars/{calendarUuid}/{path}
Overview
Authenticated event retrieval implemented at src/caldav/router.js:41 (controller.getEvent). A UUID .ics resource is resolved through the authorized calendar and returned as text/calendar with its deterministic ETag.
Authentication and access
Security scheme: basicAuth
| Control | Contract |
|---|---|
| Authentication | authenticated |
| Authorization | HTTP Basic credentials are verified by FeraAuth and the resolved principal must have read capability for the selected calendar context. |
| Licensing | The adapter has no separate local product-license middleware; it relies on FeraAuth credential verification and FeraCal calendar-access resolution for the effective instance. |
| Instance Context | Principal and instance routes supply an instance UUID. Calendar routes first resolve the calendar UUID to its owner instance, then verify credentials in that effective context. |
| Ownership | The verified FeraAuth user is resolved to a FeraCal person and calendar role; collection and event access is constrained to calendars for which that principal has the required capability. |
Parameters
| Name | Location | Type | Required | Description |
|---|---|---|---|---|
calendarUuid |
path | string (uuid) | Yes | FeraCal calendarUuid UUID used for CalDAV discovery and authorization. |
path |
path | string | Yes | Event resource filename. The basename must be a UUID and the extension must be .ics. |
