Event Notifications

The Event Notifications feature lets you create integrations that take action on events in your Backblaze B2 Cloud Storage buckets. You can create event notification rules using either the Backblaze web UI or the Backblaze API. These rules associate your webhook endpoint with a bucket, one or more event types, and, optionally, the path to a set of files. When an event that matches a rule occurs, Backblaze B2 attempts to send a signed HTTP POST message to the associated webhook endpoint.

You can use Event Notifications to perform the following tasks, as well as many others:

• Transcode video files as they are uploaded to Backblaze B2.
• Record Backblaze B2 file changes in an audit log.
• Archive metadata in a database when files are deleted from Backblaze B2.

The guides in this section provide more information about Event Notifications and how to use them.

You can also use the Backblaze B2 API to manage Event Notifications:

• Get Bucket Notification Rules
• Set Bucket Notification Rules
