Server Templates Consent Management

Problem that solved by this standard

Server GTM does not have a built-in consent management system. Most of the SGTM templates require ad_storage consent. This standard provides a way to manage consent in the SGTM templates.

Standard description

• Each template must have a consentSettingsGroup parameter.
• consentGroup must contain a adStorageConsent parameter.
• adStorageConsent must contain one of these values optional, required.
• By default, adStorageConsent must be optional.
• If adStorageConsent is required, the template must check if the consent is given and send data only if the consent is given.
• If adStorageConsent is optional, the template must send data always.
• The template must check if the consent is given by the consent_state or x-ga-gcs property.

Example Code

const eventData = getAllEventData();

if (!isConsentGivenOrNotRequired()) {
 return data.gtmOnSuccess();
}

function isConsentGivenOrNotRequired() {
 if (data.adStorageConsent !== 'required') return true;
 if (eventData.consent_state) return !!eventData.consent_state.ad_storage;
 const xGaGcs = eventData['x-ga-gcs'] || ''; // x-ga-gcs is a string like "G110"
 return xGaGcs[2] === '1';
}

Example UI

{
  "type": "GROUP",
  "name": "consentSettingsGroup",
  "displayName": "Consent Settings",
  "groupStyle": "ZIPPY_CLOSED",
  "subParams": [
    {
      "type": "RADIO",
      "name": "adStorageConsent",
      "displayName": "",
      "radioItems": [
        {
          "value": "optional",
          "displayValue": "Send data always"
        },
        {
          "value": "required",
          "displayValue": "Send data in case marketing consent given"
        }
      ],
      "simpleValueType": true,
      "defaultValue": "optional"
    }
  ]
}
