Create & Update Yandex Calendar Events via Webhook

Create & Update Yandex Calendar Events via Secure Webhook (CalDAV)

Send a webhook request with your event details—and this n8n workflow instantly creates or updates a corresponding Yandex Calendar event by generating an iCalendar (.ics) file and pushing it to Yandex using CalDAV over authenticated HTTP PUT.

What this workflow does

• Receives a POST webhook request containing event fields such as title, start, end, all-day, and an optional description (plus an optional calendarPath).
• Configures the CalDAV base URL and selects the target calendar path for Yandex.
• Generates or reuses a stable event UID so repeated requests update the same event (supporting deterministic updates if you provide a UID).
• Builds an iCalendar (.ics) event payload including UID and description.
• Uploads to Yandex Calendar via CalDAV using an authenticated HTTP PUT request with HTTP Basic Authentication (Yandex app password required).
• Responds with JSON summarizing the result: UID, event fields, HTTP status code, and whether the event was created (201) or updated (204).

Use cases

• Automate booking confirmations from your SaaS backend into Yandex Calendar.
• Update scheduled events when a user changes meeting time, title, or notes—using the same UID.
• Sync internal systems to Yandex without manual calendar editing.
