Vanilla Bean Slack Hooker

Automated notifications from your WordPress site to your Slack / Mattermost application channels and webhooks.

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
• Multiple webhook support – Send to Slack, Mattermost, Discord, 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"]
