Server events Connector events AS2 events

Transfer Family events detail reference

All events from AWS services have a common set of fields containing metadata about the event. These metadata can include the AWS service that is the source of the event, the time the event was generated, the account and Region in which the event took place, and others. For definitions of these general fields, see Event structure reference in the Amazon EventBridge User Guide.

In addition, each event has a detail field that contains data specific to that particular event. The following reference defines the detail fields for the various Transfer Family events.

When you use EventBridge to select and manage Transfer Family events, consider the following:

The source field for all events from Transfer Family is set to aws.transfer.
The detail-type field specifies the event type.

For example, FTP Server File Download Completed.
The detail field contains the data that is specific to that particular event.

For information on constructing event patterns that enable rules to match Transfer Family events, see Event patterns in the Amazon EventBridge User Guide.

For more information on events and how EventBridge processes them, see Amazon EventBridge events in the Amazon EventBridge User Guide.

SFTP, FTPS, and FTP server events

The following are the detail fields for SFTP, FTPS, and FTP server events:
