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" {}
}
