Rate limit: 120 requests per fixed minute per API key, shared by all post engagement monitor endpoints. > [!NOTE] > > Post engagement monitoring requires a **V2 workspace API key**. Legacy V1 API keys are not supported by these endpoints. Monitors and their credits belong to the V2 workspace associated with the key. Re-arm one delivered engager's webhook. Airscale resets the attempt count and sends the engager again to the monitor's **current** webhook URL with its current signing secret. Redelivery never re-runs a check and spends no credits. A paused monitor holds the delivery until it is resumed. The request accepts an empty body or `{}`. The `202` response returns `engager_id` and the new `webhook` receipt, normally `pending` with `attempt_count: 0`. If a send for the engager is already in flight, its `sending` receipt is returned unchanged. > [!WARNING] > > The engager keeps the same event ID and `Idempotency-Key: post-engagement-engager:` header. Your receiver may already have processed an `uncertain` delivery, so handle the engager idempotently. A monitor without a webhook returns `422 webhook_not_configured`. Track the outcome through the `webhook` receipt in [List engagers](https://docs.airscale.io/api-reference/post-engagement-monitors/engagers.md). ## Next step Use [Update a post engagement monitor](https://docs.airscale.io/api-reference/post-engagement-monitors/update.md) to change the webhook URL or rotate its signing secret before redelivering. ## OpenAPI ````yaml openapi.json POST /v1/post-engagement-monitors/{monitor_id}/engagers/{engager_id}/webhook/redeliver 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: New hire monitoring description: Watch companies or the market for people who start a matching role. - name: Post engagement monitoring description: >- Follow LinkedIn company pages and profiles and receive the people who engage with their posts. - name: Account description: Inspect workspace account state. - name: Miscellaneous description: >- Find website technologies and check WhatsApp availability, Meta ads, and email deliverability. paths: /v1/post-engagement-monitors/{monitor_id}/engagers/{engager_id}/webhook/redeliver: post: tags: - Post engagement monitoring summary: Redeliver an engager webhook description: >- Re-arms one delivered engager's webhook.
