Users can set a streaming destination for a top-level group to receive all audit events about the group, its subgroups, and
projects as structured JSON.
Top-level group owners can manage their audit logs in third-party systems. Any service that can receive
structured JSON data can be used as the streaming destination.
Each streaming destination can have up to 20 custom HTTP headers included with each streamed event.
NOTE:
GitLab can stream a single event more than once to the same destination. Use the `id` key in the payload to deduplicate incoming data.
## Add a new streaming destination
WARNING:
Streaming destinations receive **all** audit event data, which could include sensitive information. Make sure you trust the streaming destination.
### Use the GitLab UI
Users with the Owner role for a group can add streaming destinations for it:
1. On the top bar, select **Main menu > Groups** and find your group.
1. On the left sidebar, select **Security and Compliance > Audit events**.
1. On the main area, select **Streams** tab.
1. Select **Add streaming destination** to show the section for adding destinations.
1. Enter the destination URL to add.
1. Optional. Locate the **Custom HTTP headers** table.
1. Ignore the **Active** checkbox because it isn't functional. To track progress on adding functionality to the
**Active** checkbox, see [issue 367509](https://gitlab.com/gitlab-org/gitlab/-/issues/367509).
1. Select **Add header** to create a new name and value pair. Enter as many name and value pairs as required. You can add up to
20 headers per streaming destination.
1. After all headers have been filled out, select **Add** to add the new streaming destination.
### Use the API
To enable streaming and add a destination, users with the Owner role for a group must use the
`externalAuditEventDestinationCreate` mutation in the GraphQL API.
```graphql
mutation {
externalAuditEventDestinationCreate(input: { destinationUrl: "https://mydomain.io/endpoint/ingest", groupPath: "my-group" } ) {
errors
externalAuditEventDestination {
id
destinationUrl
verificationToken
group {
name
}
}
}
}
```
Group owners can also optionally specify their own verification token (instead of the default GitLab-generated one) using the GraphQL `auditEventsStreamingHeadersCreate`
mutation. Verification token length must be within 16 to 24 characters and trailing whitespace are not trimmed. GitLab recommends setting a cryptographically random and unique value. For example:
```graphql
mutation {
externalAuditEventDestinationCreate(input: { destinationUrl: "https://mydomain.io/endpoint/ingest", groupPath: "my-group", verificationToken: "unique-random-verification-token-here" } ) {
errors
externalAuditEventDestination {
id
destinationUrl
verificationToken
group {
name
}
}
}
}
```
Event streaming is enabled if:
- The returned `errors` object is empty.
- The API responds with `200 OK`.
Group owners can add an HTTP header using the GraphQL `auditEventsStreamingHeadersCreate` mutation. You can retrieve the destination ID
by [listing all the streaming destinations](#use-the-api-1) for the group or from the mutation above.
```graphql
mutation {
auditEventsStreamingHeadersCreate(input: { destinationId: "gid://gitlab/AuditEvents::ExternalAuditEventDestination/24601", key: "foo", value: "bar" }) {
errors
}
}
```
The header is created if the returned `errors` object is empty.
## List streaming destinations
Users with the Owner role for a group can list streaming destinations.
### Use the GitLab UI
To list the streaming destinations:
1. On the top bar, select **Main menu > Groups** and find your group.
1. On the left sidebar, select **Security and Compliance > Audit events**.
1. On the main area, select **Streams** tab.
1. To the right of the item, select **Edit** (**{pencil}**) to see all the custom HTTP headers.
### Use the API
Users with the Owner role for a group can view a list of streaming destinations at any time using the
`externalAuditEventDestinations` query type.
```graphql
query {
group(fullPath: "my-group") {
id
externalAuditEventDestinations {
nodes {
destinationUrl
verificationToken
id
headers {
nodes {
key
value
id
}
}
eventTypeFilters
}
}
}
}
```
If the resulting list is empty, then audit streaming is not enabled for that group.
You need the ID values returned by this query for the update and delete mutations.
## Update streaming destinations
Users with the Owner role for a group can update streaming destinations.
### Use the GitLab UI
To update a streaming destinations custom HTTP headers:
1. On the top bar, select **Main menu > Groups** and find your group.
1. On the left sidebar, select **Security and Compliance > Audit events**.
1. On the main area, select **Streams** tab.
1. To the right of the item, select **Edit** (**{pencil}**).
1. Locate the **Custom HTTP headers** table.
1. Locate the header that you wish to update.
1. Ignore the **Active** checkbox because it isn't functional. To track progress on adding functionality to the
**Active** checkbox, see [issue 367509](https://gitlab.com/gitlab-org/gitlab/-/issues/367509).
1. Select **Add header** to create a new name and value pair. Enter as many name and value pairs as required. You can add up to
20 headers per streaming destination.
1. Select **Save** to update the streaming destination.
### Use the API
Users with the Owner role for a group can update streaming destinations custom HTTP headers using the
`auditEventsStreamingHeadersUpdate` mutation type. You can retrieve the custom HTTP headers ID
by [listing all the custom HTTP headers](#use-the-api-1) for the group.
```graphql
mutation {
externalAuditEventDestinationDestroy(input: { id: destination }) {
errors
}
}
```
Streaming destination is updated if:
- The returned `errors` object is empty.
- The API responds with `200 OK`.
Group owners can remove an HTTP header using the GraphQL `auditEventsStreamingHeadersDestroy` mutation. You can retrieve the header ID
by [listing all the custom HTTP headers](#use-the-api-1) for the group.
```graphql
mutation {
auditEventsStreamingHeadersDestroy(input: { headerId: "gid://gitlab/AuditEvents::Streaming::Header/1" }) {
errors
}
}
```
The header is deleted if the returned `errors` object is empty.
## Delete streaming destinations
Users with the Owner role for a group can delete streaming destinations.
When the last destination is successfully deleted, streaming is disabled for the group.
### Use the GitLab UI
To delete a streaming destination:
1. On the top bar, select **Main menu > Groups** and find your group.
1. On the left sidebar, select **Security and Compliance > Audit events**.
1. On the main area, select the **Streams** tab.
1. To the right of the item, select **Delete** (**{remove}**).
To delete only the custom HTTP headers for a streaming destination:
1. On the top bar, select **Main menu > Groups** and find your group.
1. On the left sidebar, select **Security and Compliance > Audit events**.
1. On the main area, select the **Streams** tab.
1. To the right of the item, **Edit** (**{pencil}**).
1. Locate the **Custom HTTP headers** table.
1. Locate the header that you wish to remove.
1. To the right of the header, select **Delete** (**{remove}**).
1. Select **Save** to update the streaming destination.
### Use the API
Users with the Owner role for a group can delete streaming destinations using the
`externalAuditEventDestinationDestroy` mutation type. You can retrieve the destinations ID
by [listing all the streaming destinations](#use-the-api-1) for the group.
```graphql
mutation {
externalAuditEventDestinationDestroy(input: { id: destination }) {
errors
}
}
```
Streaming destination is deleted if:
- The returned `errors` object is empty.
- The API responds with `200 OK`.
Group owners can remove an HTTP header using the GraphQL `auditEventsStreamingHeadersDestroy` mutation. You can retrieve the header ID
by [listing all the custom HTTP headers](#use-the-api-1) for the group.
```graphql
mutation {
auditEventsStreamingHeadersDestroy(input: { headerId: "gid://gitlab/AuditEvents::Streaming::Header/1" }) {
errors
}
}
```
The header is deleted if the returned `errors` object is empty.
## Verify event authenticity
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/345424) in GitLab 14.8.
Each streaming destination has a unique verification token (`verificationToken`) that can be used to verify the authenticity of the event. This
token is either specified by the Owner or generated automatically when the event destination is created and cannot be changed.
Each streamed event contains the verification token in the `X-Gitlab-Event-Streaming-Token` HTTP header that can be verified against
the destination's value when [listing streaming destinations](#list-streaming-destinations).
### Use the GitLab UI
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/360814) in GitLab 15.2.
Users with the Owner role for a group can list streaming destinations and see the verification tokens:
1. On the top bar, select **Main menu > Groups** and find your group.
1. On the left sidebar, select **Security and Compliance > Audit events**.
1. On the main area, select the **Streams**.
1. View the verification token on the right side of each item.
## Event type filters
> Event type filters API [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/344845) in GitLab 15.7.
When this feature is enabled for a group, you can use an API to permit users to filter streamed audit events per destination.
If the feature is enabled with no filters, the destination receives all audit events.
A streaming destination that has an event type filter set has a **filtered** (**{filter}**) label.
### Use the API to add an event type filter
Prerequisites:
- You must have the Owner role for the group.
You can add a list of event type filters using the `auditEventsStreamingDestinationEventsAdd` query type:
```graphql
mutation {
auditEventsStreamingDestinationEventsAdd(input: {
destinationId: "gid://gitlab/AuditEvents::ExternalAuditEventDestination/1",
eventTypeFilters: ["list of event type filters"]}){
errors
eventTypeFilters
}
}
```
Event type filters are added if:
- The returned `errors` object is empty.
- The API responds with `200 OK`.
### Use the API to remove an event type filter
Prerequisites:
- You must have the Owner role for the group.
You can remove a list of event type filters using the `auditEventsStreamingDestinationEventsRemove` query type:
```graphql
mutation {
auditEventsStreamingDestinationEventsRemove(input: {
destinationId: "gid://gitlab/AuditEvents::ExternalAuditEventDestination/1",
eventTypeFilters: ["list of event type filters"]
}){
errors
}
}
```
Event type filters are removed if:
- The returned `errors` object is empty.
- The API responds with `200 OK`.
## Payload schema

Streaming audit events can be sent when authenticated users push, pull, or clone a project's remote Git repositories:
- [Using SSH](../user/ssh.md).
- Using HTTP or HTTPS.
- Using the **Download** button (**{download}**) in GitLab UI.
Audit events are not captured for users that are not signed in. For example, when downloading a public project.
To configure streaming audit events for Git operations, see [Add a new streaming destination](#add-a-new-streaming-destination).
