Rate limit: 120 requests per fixed minute per API key, shared by all job-change monitor endpoints. > [!NOTE] > > Job-change monitoring requires a **V2 workspace API key**. V1 (Bubble) API keys are not supported by these endpoints. Monitors and monitoring credits belong to the V2 workspace associated with the key. Mark one event as read after your integration has handled it. The response returns the event with its `read_at` timestamp, and the monitor's unread count decreases. The request accepts an empty body or `{}`. A body that is present but not valid JSON returns `400`. > [!NOTE] > > Treat the event ID as the durable acknowledgement key. Webhook retries use the same event ID, so processing it idempotently prevents duplicate downstream work. An event can be marked read once. Marking an event that is already read returns `404 event_not_found`, so treat that response as already acknowledged when you know the event exists. Reading an event does not delete it. You can still retrieve it through [List job-change events](https://docs.airscale.io/api-reference/job-change-monitors/events.md) or the monitor detail response. ## Next step Review [Create a job-change monitor](https://docs.airscale.io/api-reference/job-change-monitors/create.md) for webhook setup and signature verification. ## OpenAPI ````yaml openapi.json POST /v1/job-change-monitors/{monitor_id}/events/{event_id}/read openapi: 3.1.0 info: title: Airscale Public API version: '2026-09-11' description: >- Search, enrich, resolve public business data, and monitor job changes with Airscale. x-airscale-source-repository: ViceScale/airscale-code x-airscale-source-sha: 1de19e1b70a052a4b8d9c2075021a7e5e7a94d51 servers: - url: https://api.airscale.io description: Production security: - bearerAuth: [] tags: - name: Search and discovery description: Search people, companies, and the web. - name: Contact data description: Find professional and personal contact data. - name: Profiles and reverse lookup description: Extract profiles or resolve a person from known contact data. - name: Post engagement description: Retrieve and enrich people who liked or commented on LinkedIn posts. - name: LinkedIn content description: >- Search LinkedIn posts, read profile and company feeds, and retrieve profile comments and comment reactions. - name: Job change monitoring description: Track LinkedIn profiles and receive job-change events. - name: Account description: Inspect workspace account state. - name: Miscellaneous description: >- Find website technologies and check WhatsApp availability, Meta ads, and email deliverability. paths: /v1/job-change-monitors/{monitor_id}/events/{event_id}/read: post: tags: - Job change monitoring summary: Mark a job-change event as read description: >- Marks one unread event read and returns the event with its read_at timestamp.
