Omitting `subscription_id` upserts the row for that tuple. * Only `Critical`, `Warning`, and `Info` severities are valid; `enabled` defaults to true. * Every call is recorded in the account audit log. Don't put secrets in request fields. ## OpenAPI ````yaml /api-reference/on-call.openapi.en.json post /incident-trigger-subscription/upsert openapi: 3.1.0 info: title: Flashduty Open API description: >- Public HTTP API for the Flashduty incident management platform — incidents, notification templates, channels, schedules, monitors, RUM, and platform administration. Every operation is authenticated with an `app_key` query parameter issued from the Flashduty console under Account → APP Keys. Responses follow a uniform envelope: `{ request_id, data }` on success, `{ request_id, error }` on failure. version: 1.0.0 servers: - url: https://api.flashcat.cloud description: Flashduty Open API security: - AppKeyAuth: [] tags: - name: On-call/Incidents description: '' - name: On-call/Channels description: '' - name: On-call/Alerts description: >- Search, inspect, and act on alerts.
