Developer Integration

Learnosity APIs are initialized client-side via lightweight JavaScript SDKs. A typical integration looks like:

<script src="https://items.learnosity.com/?v2023.1.LTS"></script>
<script>
  var itemsApp = LearnosityItems.init(signedRequest, {
    readyListener: function() { console.log('Items API ready'); },
    errorListener: function(e) { console.error(e); }
  });
</script>
