WordPress new comment notifications on your phone.

Three steps to your first push

How to set up the WordPress new comment webhook

1. Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
2. Copy the PHP snippet from the setup notes below. It already contains your endpoint URL.
3. Save it as a new .php file in wp-content/mu-plugins/ on your site (create the folder if it doesn't exist).
4. WordPress loads it automatically. Trigger a New comment to test.
5. WordPress doesn't send webhooks by itself, so this recipe comes with a small **must-use plugin**. Save the code below as `wp-content/mu-plugins/justpush-new-comment.php` (create the `mu-plugins` folder if it doesn't exist). WordPress loads files there automatically; there's nothing to activate.
6. ```php
7. <?php
8. /**
9. Plugin Name: JustPush — New comment
10. Description: Sends a push through JustPush Studio when a new comment is posted.
11. */
12. add_action('comment_post', function ($comment_id, $approved) {
13. // Spam and trashed comments aren't worth a push.
14. if ($approved === 'spam' || $approved === 'trash') {
15. return;
16. }
17. $comment = get_comment($comment_id);
18. // Real comments only, not pingbacks or trackbacks.
19. if (!$comment || !in_array($comment->comment_type, array('comment', ''), true)) {
20. return;
21. }
22. $pending = (string) $approved !== '1';
23. wp_remote_post('your webhook URL', array(https://••••••••/•••••••• your personal URL, shown after install
24. 'blocking' => false, // don't slow the page down waiting for JustPush
25. 'timeout' => 3,
26. 'headers' => array('Content-Type' => 'application/json'),
27. 'body' => wp_json_encode(array(
28. 'event' => 'comment.created',
29. 'site' => get_bloginfo('name'),
30. 'status' => $pending ? 'pending' : 'approved',
31. 'author' => $comment->comment_author,
32. 'post_title' => get_the_title($comment->comment_post_ID),
33. 'excerpt' => wp_trim_words($comment->comment_content, 20),
34. 'url' => $pending
35. ? admin_url('edit-comments.php?comment_status=moderated')
36. : get_comment_link($comment),
37. )),
38. ));
39. }, 10, 2);
40. ```
41. To stop the notifications, delete the file.

What runs when the webhook arrives

Studio calls handleRequest(request) with the incoming webhook and sends the message it returns. It's yours after install; change anything.

The WordPress comment.created webhook

This is what WordPress sends to your URL for new comment. It is a sample, trimmed to the fields recipes use.
