Enable TrustArc integrations. Sends a "TrustArc Consent" data layer event, which contains "trustarc.consent" as a string indicating each consent status, much like how OneTrust reports consent updates.

CMAPI_Integration.js

<script>
  var __i__ = self.postMessage && setInterval(function () {
    if (self.PrivacyManagerAPI && __i__) {
      var apiObject = {
        PrivacyManagerAPI:
        {
          action: "getConsentDecision",
          timestamp: new Date().getTime(),
          self: self.location.host
        }
      };
      self.top.postMessage(JSON.stringify(apiObject), "*");
      __i__ = clearInterval(__i__);
    }
  }, 50);
  
  self.addEventListener("message", function (e, d) {
    try {
      if (e.data && (d = JSON.parse(e.data)) && (d = d.PrivacyManagerAPI) && d.capabilities && d.action == "getConsentDecision") {
        var newDecision = self.PrivacyManagerAPI.callApi("getGDPRConsentDecision", self.location.host).consentDecision.toString();
        self.dataLayer && self.dataLayer.push(
          newDecision==="0" ?  {"event": "TrustArc Pre-Consent"}
                            :  {"event": "TrustArc Consent", "trustarc": {"consent": newDecision}}
        );
      }
    } catch (xx) { /** not a cm api message **/ }
  });
</script>

The idea of this gist is to send a single data layer push containing the consent agreed as metadata within the push.

Amazing, just what I needed as well.

Thanks for this 🙏
