Monitor emails

To set up email monitoring with the Email Audit API, an adminstrator sets a date range for the auditor to receive a copy of a particular user's sent and received emails as an attachment. The maximum number of monitor creation and deletion requests per day is 1000 requests. This limit is per domain, and includes all requests made by any administrator during the day.

A monitored email scenario includes three types of users:

Administrator — Any domain administrator can create, retrieve, update, and delete an email monitor using the monitor resource of the Email Audit API. In addition, an administrator can use the API to download the mailbox. These operations can only be done within the domain over which the administrator exercises control.
Source user — The source user is the user who receives or sends messages that are being audited by the monitoring destination user. Any domain administrator or account user can be a source user. The source user must be in the same domain as the administrator and destination user.
Destination user — The destination user is the auditor who receives the audited email messages.
- Receives blind carbon copies (Bcc) of all incoming and outgoing email messages including inbound and outbound attachments, forwarded messages, and email messages sent from mobile devices.
- As an option, a domain administrator can enable additional auditing features for the destination user. The optional features include the auditing of saved email drafts, the auditing of archived Hangouts chats with other users who can be in or outside of the domain.
- Even though the destination user receives a Bcc copy of the message, the Bcc association isn't visible in the message headers accessible in the source user's account.
- Each audited email message is sent to the destination user as an email attachment. And the domain administrator can configure these messages to be either the full email message or only the message headers.
- This destination user must have an active email account in the monitored domain. This must be the same domain associated with the administrator and source user.
- A destination user can be an administrator or a user within the domain. And, this destination user can switch roles to become a source user audited by another destination user who, in turn, receives copies of all audited email messages sent to the first destination user.
- A domain administrator creates one audited email monitor for one unique 'destination user - source user' pair. In other words, the audit relationship is one destination user to one source user. Each audit is done using an API monitor resource. Using multiple API monitors, a destination user can audit many users in the domain. And, using multiple API monitors, many destination users can audit one source user.
- If an additional API monitor is created or an existing API monitor is updated for a 'destination user - source user' pair, the monitor which was the last created supersedes any pre-existing monitors for this pair. Basically, this is how you update an API monitor. For more information about updating a monitor, see Update an email monitor.

Create an email monitor

To create an email monitor, send the following POST request with the email monitor resource:

POST https://apps-apis.google.com/a/feeds/compliance/audit/mail/monitor/DOMAIN_NAME/SOURCE_USERNAME

Replace the following:

DOMAIN_NAME: the Google Workspace domain name—for example, example.com.
SOURCE_USERNAME: the username that you want to monitor.

The POST request contains the following Content-type header:

Content-type: application/atom+xml

For a full list of parameters to use in an email monitor request, see Resources: monitor.

Example for creating a new monitor

The example uses the following parameters:

The user to be audited is amal@example.com.
The destUserName is izumi.
The beginDate is June 15, 2022, 00:00 hours.
The endDate is June 30, 2022, 23:20 hours.
The incomingEmailMonitorLevel is FULL_MESSAGE.
The outgoingEmailMonitorLevel is HEADER_ONLY.
The draftMonitorLevel is FULL_MESSAGE.
The chatMonitorLevel is FULL_MESSAGE.

If successful, the server returns a 201 CREATED status code and an AtomPub entry with the entry element showing new monitor settings:

Update an email monitor

When updating a monitor with the same source user and destination user, the initial monitor's property settings are replaced by the new settings.

To update the audit configuration in an email monitor, send a POST request to the monitor feed's URI and include the Authorization header:

POST https://apps-apis.google.com/a/feeds/compliance/audit/mail/monitor/DOMAIN_NAME/SOURCE_USERNAME

Replace the following:

DOMAIN_NAME: the Google Workspace domain name—for example, example.com.
SOURCE_USERNAME: the username of the email monitor that you want to update.

Example for updating an email monitor

This example updates the monitor created in the example for creating an email monitor by updating the required property endDate and the optional property chatMonitorLevel. This example uses the following parameters:

The new endDate is August 30, 2022, 23:20 hours.
The chatMonitorLevel is now HEADER_ONLY.
The user to be audited remains amal@example.com.
The destUserName remains izumi.

The monitor properties that weren't updated revert to their default values. For instance, in this example, the incomingEmailMonitorLevel and outgoingEmailMonitorLevel properties revert to FULL_MESSAGE, and the draftMonitorLevel reverts to NONE.

Protocol

POST https://apps-apis.google.com/a/feeds/compliance/audit/mail/monitor/example.com/amal

</atom:entry>

If successful, the server returns a 201 CREATED status code and an AtomPub entry with the updated entry elements. The properties that weren't updated and shown in the response revert to their default values.

Retrieve all email monitors of a source user

To retrieve all monitors associated with a source user, make an HTTP GET request to the monitor feed URI, using the UTC format for the date, and include the Authorization header:

GET https://apps-apis.google.com/a/feeds/compliance/audit/mail/monitor/DOMAIN_NAME/SOURCE_USERNAME

Replace the following:

DOMAIN_NAME: the Google Workspace domain name—for example, example.com.
SOURCE_USERNAME: the username of the email monitor that you want to retrieve.

This operation has no parameters in the request body, so the XML body is empty.

Example for retrieving all email monitors

This example retrieves all the monitors created for the user amal@example.com:

Protocol

GET https://apps-apis.google.com/a/feeds/compliance/audit/mail/monitor/example.com/amal

If successful, the server returns a 201 CREATED status code and an AtomPub feed with the entry elements for two monitors showing the settings for two destination users (izumi@example.com, taylor@example.com).
