This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



Webhooks are a simple paradigm for developing instant notifications and mashups based on simple HTTP requests. With HookPress you can set up webhooks so that a specified URL (a public service or something you set up) is requested when certain WordPress actions occur. Possible uses include generating push notifications or using non-PHP web technology to extend WordPress.

A tutorial video is available on

As seen on!

To learn about the various hooks WordPress provides, please consult the WordPress Plugin API’s Action Reference and Filter Reference. Not all hooks are supported yet, but more are in the works.

To learn more about webhooks, take a look at the wikipedia page and also The Pushbutton Web by Anil Dash. Webhooks champion Jeff Lindsay’s excellent slides are a particularly good place to start.

To write and host a target script The easiest option is to set up a script on your own server to catch POST requests and act on them. Requestbin is a nice, free service which will host an endpoint, collect all requests, and let you inspect them, which is a great way to test requests generated by your webhooks. There is also a PHP script which does a simple version of this, test.php, included with HookPress.


Upload the HookPress plugin to your blog’s wp-content/plugins/ directory and activate. In the admin section, go to Settings > Webhooks to add new webhooks.


If you have a feature request or question, please use the HookPress support forum.

How does HookPress affect performance?

HookPress currently makes requests synchronously so can measurably affect performance. I highly recommend using a caching plugin such as WP-SuperCache to stem the performance hit. If your filters’ results are time-sensitive or dependent on external data sources as well, make sure to set an appropriate cache expiration time.


unable to add web hook

try to add webhook its showing select one field at least i try with ctrl-click to add but its never response or add any feild

Plugin is broken

Unfortunately this plugin is broken and doesn’t work with WordPress 4.8.2: it’s not possible to select fields to be sent to a webhook, and therefore the plugin is useless (you can’t add a webhook this way).

Still works fine

This has been absolutely essential as I create cached versions of current WordPress posts for use elsewhere in the site. It has been working well and quietly for years. (Posted January 2018; using latest WordPress with PHP 7.0).

  • Important security fix to the test endpoint, test.php.
  • Code cleanup, fix bugs introduced in previous version.


  • Upgraded to work properly with jQuery 1.9+. Props liquidgecha.
  • Dropped the initial 0. in the version number, as that was just ridiculous. 🙂


  • Fix to register the right number of incoming arguments for actions.

    • supports webhooks based on WP actions

Future plans

  • Editing webhooks (rather than deleting and adding)
  • More custmization on a per-webhook basis
