Vanilla Bean Slack Hooker

Automated notifications from your WordPress site to your Slack, Mattermost and Google Chat channels.

Notify one or more webhook endpoints when things happen on your site: plugin installs and updates, post publication, comments, signups, PHP errors, WooCommerce sales, or anything you like via shortcodes, hooks and filter functions.

There is no limit to the ways you may integrate this plugin.

It supports all other Vanilla Bean plugins and is available for under-the-hood use as well as shortcode access.

Key Features

• Real-time WordPress notifications – Post status changes, comments, user registrations
• WooCommerce integration – Sales notifications with order details
• Plugin management alerts – Install, update, and deletion notifications
• PHP Error Alerts – Route PHP errors to Slack with a call trace and configurable exemptions. Off by default (NEW in 5.6.4)
• Multiple webhook support – Send to Slack, Mattermost, Google Chat, or custom endpoints
• Formatted data messages – Rich attachments with structured name-value pairs (NEW in 5.5.2)
• Smart queueing – Non-blocking message delivery with optional immediate sending
• Email fallback – Send notifications via email when webhooks aren’t available
• Shortcode support – Easy integration in posts and pages
• Programmatic API – Full developer access with PHP functions

Shortcode Examples

[slackhooker text="Here is a message from my WordPress site"]

or

[slackhooker text="Here is a message" channel="general" username="My WordPress"]

or

[slackhooker text="Here is a message" channel="https://myorg.slack.com/services/xxoxlsodsfsfsdfds#channelname" username="My WordPress"]

Messages are queued last in the PHP process to ensure your other page processing is not interrupted, but you can override:

[slackhooker text="Here is a message from my WordPress." sendnow="true"]

Multiple or custom webhooks supported:

[slackhooker text="Here is a message to multiple webhooks" alsoto="https://hooks.slack.com/services/T03TDTbUF/BBG9SQV6X/abcdefghij,https://hooks.slack.com/services/T03TDTbUF/BBG9SQV6X/abcxxxxxxx"]
