LTI Advantage - Sample JSON

Overview

This document documents sample JSON between the Blackboard Learn LMS and an LTI Advantage Tool Provider. We’ll be using https://github.com/blackboard/BBDN-LTI-Tool-Provider-Node for our examples. One use case we’re often asked about is doing video embeds in Blackboard Learn content. That will be our first, and for now, only example.

How to Embed LTI Link Items into the editor via Deep Linking

When adding content back from the internal tool for LTI 1.1/Deep Linking 1.0, you can specify custom JSON, use:

{
  "@context": "http://purl.imsglobal.org/ctx/lti/v1/ContentItem",
  "@graph": [
    {
      "@type": "LtiLinkItem",
      "@id": ":item1",
      "title": "LTI embedded-app test",
      "mediaType": "text/html",
      "url": "https://lti-tool.dev.bbpd.io/lti",
      "placementAdvice": {
        "displayWidth": 147,
        "displayHeight": 184,
        "presentationDocumentTarget": "iframe"
      }
    }
  ]
}

For LTI 1.3+/Deep Linking 2.0+ use:

{
  "type": "ltiResourceLink",
  "title": "An Embedded Resource",
  "text": "A description",
  "url": "https://lti-tool-jwt.dev.bbpd.io/lti13",
  "iframe": {
    "width": 500,
    "height": 800
  }
}
