ReplyBox can send webhook events that notify your application any time a new comment is posted. This is especially useful for notifying external services such as Zapier of new comments.

To add a webhook endpoint, head over to your site dashboard and navigate to the Notifications tab. Click Add Endpoint. Webhooks require a Pro subscription.

ReplyBox add webhook endpoint

When a new comment is submitted, a POST request will be made to your endpoint with the following JSON payload:

  "user": {
    "name": "John Doe",
    "avatar_url": ""
  "comment": {
    "id": 12345,
    "url": "",
    "parent_id": 1234,
    "markdown": "I am ~~never~~ wrong.",
    "html": "<p>I am <strike>never</strike> wrong.</p>",
    "plaintext": "I am never wrong.",
    "spam": false
  "page": {
    "id": 123,
    "url": "",
    "identifier": "my-awesome-post",
    "title": "My Awesome Post"
