Overview (SDK for C)

OBS provides the event notification function. When this function is enabled, you will be notified of all specified operations on the bucket through simple message notification (SMN). An event notification contains the following configurations:

  • A unique ID. If no ID is specified, OBS will automatically assign one.
  • The URN of the event notification topic. Once OBS detects specific events in a bucket, it sends a notification to this topic.
  • List of event types that need to be notified.
  • Filtering rules. Objects can be filtered based on the prefixes or suffixes.

For more information, see Event Notifications.
