Webhook Events

Comment received event

Fired when a new comment is received on a tracked post. Delivered for Instagram, Facebook, Threads, YouTube, LinkedIn, Bluesky, Reddit and TikTok. X/Twitter does NOT fire this event. Instagram, Facebook and TikTok arrive in real time from the platform's own webhook; the rest are poll-driven, so delivery is not instant. TikTok needs an account connected through the TikTok for Business app.

postWebhookcomment.received

Payload

idstring required

Stable webhook event ID: the dedupe key, also sent as the X-Zernio-Event-Id header and identical on every retry and redelivery. It identifies the event only, never an account or other resource.

testboolean

Always true when present: only a sample sent by POST /v1/webhooks/test with an event carries it. Real deliveries never do.

event'comment.received' required

timestampstring date-time required

UTC time at which Zernio generated this event (set once when the event payload is built, before delivery is queued). Retries and redeliveries keep the original value, so it reflects the event, not the delivery attempt.

Example payload

{
  "profiles": [
    {
      "externalId": "tenant_42"
    }
  ]
}

Response

Webhook received successfully

Changes

Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
