The base tag

This base tag should be included on every page of your website. It will generate a custom profile key in the background and store it in a cookie. This profile key is used in various requests

<script>
    (function(w, d, l, i, u) {
      w['_twa'] = l;
      w[l] = w[l] || [];
      w[l].push({ 'twa.start': new Date().getTime(), event: 'twa.js' });
      w[l].push({ 'twa.instance': i, event: 'twa.init' });
      var f = d.getElementsByTagName('script')[0],
          j = d.createElement('script');
      j.async = true;
      j.src = u;
      f.parentNode.insertBefore(j, f);
    })(window, document, 'tweakwiseLayer', '{INSTANCEKEY}', "//navigator-analytics.tweakwise.com/bundles/scout.js");
</script>

Replace {INSTANCEKEY} with your Tweakwise instance key.

The profile key

Customer identification is done through a profile key. This is our way to identify your customers using a unique identifier.

Using custom profile key

In some cases, you might want to determine the profile key yourself. For example, if you want to support cross-device personalization, it is recommended to use the currently authenticated user. Use this extended version of the base tag to pass your own custom profile key to the tag.

<script>
    var profileKey = '{PROFILEKEY}';

    (function(w, d, l, i, p, u) {

      w['_twa'] = l;
      w[l] = w[l] || [];
      w[l].push({ 'twa.start': new Date().getTime(), event: 'twa.js' });
      w[l].push({ 'twa.instance': i, event: 'twa.init' });
      
      p && w[l].push({ 'twa.profile': p, event: 'twa.profile' });
  		if(p){ w[l].getProfileKey = function(){ return p; } }

      var f = d.getElementsByTagName('script')[0],
          j = d.createElement('script');
      j.async = true;
      j.src = u;
      f.parentNode.insertBefore(j, f);

    })(window, document, 'tweakwiseLayer', '{instancekey}', profileKey, "//navigator-analytics.tweakwise.com/bundles/scout.js");
    </script>

Replace {INSTANCEKEY} with your Tweakwise instance key.

Replace {PROFILEKEY} with your custom profile key.

You can determine the profile key yourself. Generally account id's are used for logged-in users and visitor-id's for anonymous users.

Format of a custom profile key

The profile key should be a string with a maximum length of 100 characters.

Accepted characters:

• A-Z or a-z
• 0-9
• Dash (-)

Profile keys with other characters will not be processed correctly.

If no profile key is supplied, our Tweakwise Analytics JS will generate a unique identifier for the current user.
