WordPress updates available notifications on your phone.

Three steps to your first push

How to set up the WordPress updates available 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 Updates available 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-updates-available.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 — Updates available
10. Description: Sends a push through JustPush Studio when WordPress, plugin or theme updates are available.
11. */
12. // Check twice a day (WordPress already looks for updates on its own schedule), and only
13. // push when the list of available updates has changed since the last push.
14. add_action('justpush_check_updates', function () {
15. require_once ABSPATH . 'wp-admin/includes/plugin.php';
16. require_once ABSPATH . 'wp-admin/includes/update.php';
17. $items = array();
18. foreach ((array) get_core_updates() as $update) {
19. if (isset($update->response) && $update->response === 'upgrade') {
20. $items[] = 'WordPress ' . $update->current;
21. }
22. }
23. foreach (get_plugin_updates() as $plugin) {
24. $items[] = $plugin->Name . ' ' . $plugin->update->new_version;
25. }
26. foreach (get_theme_updates() as $theme) {
27. $items[] = $theme->get('Name') . ' ' . $theme->update['new_version'];
28. }
29. // Nothing waiting: forget what we sent, so the next update pushes again.
30. if (!$items) {
31. delete_option('justpush_updates_sent');
32. return;
33. }
34. $fingerprint = md5(implode('|', $items));
35. if (get_option('justpush_updates_sent') === $fingerprint) {
36. return;
37. }
38. update_option('justpush_updates_sent', $fingerprint, false);
39. wp_remote_post('your webhook URL', array(https://••••••••/•••••••• your personal URL, shown after install
40. 'blocking' => false, // don't slow the page down waiting for JustPush
41. 'timeout' => 3,
42. 'headers' => array('Content-Type' => 'application/json'),
43. 'body' => wp_json_encode(array(
44. 'event' => 'updates.available',
45. 'site' => get_bloginfo('name'),
46. 'items' => $items,
47. 'url' => admin_url('update-core.php'),
48. )),
49. ));
50. });
51. add_action('init', function () {
52. if (!wp_next_scheduled('justpush_check_updates')) {
53. wp_schedule_event(time() + 60, 'twicedaily', 'justpush_check_updates');
54. }
55. });
56. ```
57. The check runs on WP-Cron, which needs visits to your site to trigger. If you remove the file later, the scheduled `justpush_check_updates` event stays behind but does nothing.
58. 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 updates.available webhook

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