Example: Google Tag Manager Server Side#

You can use the HTTP target to send events to Google Tag Manager Server Side, where the Snowplow Client tag is installed.

To do this, you will need to include a transformation that converts your events to JSON — spEnrichedToJson.

Here’s an example configuration. Replace <your-gtm-host> with the hostname of your Google Tag Manager instance, and — optionally — <preview-token> with your preview mode token.

target {
  use "http" {
    url                        = "https://<your-gtm-host>/com.snowplowanalytics.snowplow/enriched"
    request_timeout_in_seconds = 5
    content_type               = "application/json"

    # this line is optional, in case you want to send events to GTM Preview Mode
    headers                    = "{\"x-gtm-server-preview\": \"<preview-token>\"}"
  }
}

transform {
  use "spEnrichedToJson" {}
}
