The script injected to the browser is based on the code example provided by BlueConic on this page.

<script>
(function postSegmentsWhenReady() {
       function postSegments() {
       var segments = window.blueConicClient.getSegments().map((el) => {
            return el.id
        });

       if (segments.length) {
          var retrieveSegmentsXhr = new (XMLHttpRequest || ActiveXObject)('MSXML2.XMLHTTP.3.0');
          retrieveSegmentsXhr.open('POST', '/plugins/public/blueconic/segments', true);
          retrieveSegmentsXhr.setRequestHeader('Content-type', 'application/json');
          retrieveSegmentsXhr.withCredentials = true;
          retrieveSegmentsXhr.send(JSON.stringify(segments));
       }
    }

    if (typeof window.blueConicClient !== 'undefined' &&
       typeof window.blueConicClient.event !== 'undefined' &&
       typeof window.blueConicClient.event.subscribe !== 'undefined') {
       postSegments();
    } else {
    window.addEventListener('onBlueConicLoaded', function () {
       postSegments();
       }, false);
    }
})();
</script>

If you are creating your own script to POST segments to the HTTP listener, you should be able to use the script above as an example. Please remember to include:

• A valid session ID for your user in the `Cookie` header, for example:

  Cookie: blaize_session=70635d53-b265-4156-bd8d-ec479a95dec5

• Any segments that you retrieve from BlueConic should be included in the request body as a stringified JSON array of strings.
