To link a tracker to a geofence collection you can use either the console, API, or CLI. The following procedures walk you through each option.

Link a tracker resource to a geofence collection using the Amazon Location Service console:

1.  Open the Amazon Location console.

1.  In the left navigation pane, choose **Trackers**.

1.  Under **Device Trackers**, select the name link of the target tracker.

1.  Under **Linked Geofence Collections**, choose **Link Geofence Collection**.

1.  In the **Linked Geofence Collection window**, select a geofence collection from the dropdown menu.

1.  Choose **Link**.

1.  After you link the tracker resource, it will be assigned an Active status.

Link a tracker resource to a geofence collection using the Amazon Location APIs:

Use the `AsssociateTrackerConsumer` operation from the Amazon Location Trackers APIs. The following example uses an API request that associates an `ExampleTracker` with a geofence collection using its Amazon Resource Name (ARN).

```
        POST /tracking/v0/trackers/ExampleTracker/consumers
        Content-type: application/json
        {
           "ConsumerArn": "arn:aws:geo:us-west-2:123456789012:geofence-collection/GOECOLLECTION_NAME"
            }
```

Link a tracker resource to a geofence collection using AWS CLI commands:

Use the `associate-tracker-consumer ` command. The following example uses an AWS CLI to create a geofence collection called `GOECOLLECTION_NAME`.

```
aws location \
associate-tracker-consumer \
    --consumer-arn "arn:aws:geo:us-west-2:123456789012:geofence-collection/GOECOLLECTION_NAME" \
    --tracker-name "ExampleTracker"
```
