Webhook event types

ButterCMS automatically sends webhook notifications for various content events including blog posts, pages, and collection items. These events enable real-time integration with your applications, triggering immediate responses to content changes. Event Types: Webhooks are triggered for create, update, publish, unpublish, and delete operations across all content types. Delivery Method: All webhook events are delivered as HTTP POST requests to your configured endpoint URLs, with JSON payloads containing event metadata and complete content data.

Event timing

Understanding when events fire helps you build reliable integrations:

​

Immediate events

These events fire immediately when the action is taken:

• *.draft - Fires immediately when content is saved
• *.delete - Fires immediately when content is deleted
• *.unpublished - Fires immediately when content is unpublished

​

Conditional events

These events may fire immediately or be delayed:

• *.published - Fires immediately for manual publish, or at scheduled time for scheduled content
• media.videouploaded - Fires when video processing completes (may take time for large files)
