# Automation Webhooks

> The comment.received event and the other notifications your webhook starts getting.

As soon as the feature is on, your [webhook](/api-reference/webhooks) starts receiving notifications for new activity. If your webhook has no event filter, you get them automatically:

| Event                                                       | When it fires                                                                                                                                                                                 |
| :---------------------------------------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `comment.received`                                          | Someone else commented on one of your posts. Facebook and Instagram: posts published through bundle.social. TikTok: those plus imported videos, once we've flipped the TikTok switch for you. |
| `conversation.created`, `conversation.message.created`, ... | New DMs and conversation changes, see [Direct Messages → Webhooks](/api-reference/direct-messages/webhooks)                                                                                   |

`comment.received` fires for every such comment (comments by the account itself and your automated replies are left out), whether or not a flow reacts to it, so you can also use it to build a live comments feed. `data.comment` has the same shape as items from the [Comments API](/api-reference/comments) (on imported TikTok videos, `postId` is `null` both there and in `data`, and `comment.importedPostId` is set instead), and its `id` is exactly the `fetchedCommentId` you use for [private replies](/api-reference/direct-messages/private-replies) and [test runs](/api-reference/automations/testing-and-logs#test-a-flow).

```json theme={null}

  "type": "comment.received",

    "comment": {
      "id": "fetched_1",

    },

<Warning>
  **Your endpoint has to keep up.** New comments and DMs can mean a lot of events. Answer each one with a `2xx` within 15 seconds, **including event types you don't handle**, and do the heavy work asynchronously. If your endpoint keeps failing and goes **7 days without a single successful delivery**, we disable it automatically. You'll get an email and a dashboard notification, and you then have to re-enable it (or set up a new one) in the [Webhooks dashboard](https://bundle.social/dashboard/organization/webhooks). Events sent while it was disabled are not replayed. More in [Webhooks](/api-reference/webhooks).
