Ever tried to plug a learning platform into a campus LMS and felt like you were wrestling a three‑headed beast?
You click “Add Tool,” copy a secret key, stare at a blank screen, and wonder if anyone ever got this to work without pulling their hair out. Turns out a lot of folks are stuck in that exact spot, especially when the tool in question is the Highlander API for LTI Worth keeping that in mind..
If you’ve landed on this page, you’re probably looking for a clear, no‑fluff guide that actually gets you from “what is this thing?In real terms, ” to “I’m using it in my course tomorrow. ” Let’s dive in It's one of those things that adds up..
What Is the Highlander API LTI Tool?
At its core, the Highlander API is a set of web services that let third‑party educational apps talk to a learning management system (LMS) using the Learning Tools Interoperability (LTI) standard. Think of it as a diplomatic passport for your external content: it tells the LMS who you are, what you’re allowed to do, and how to hand off a student’s identity securely Surprisingly effective..
The “Highlander” name comes from the vendor’s branding—Pearson’s Highlander suite of assessment and analytics products. The API lives behind a URL that looks something like https://tpi.bb.pearsoncmg.So com/highlander/api, and it expects LTI launch requests that follow the 1. 3 (or newer 1.Also, 3. 1) spec. On the flip side, in practice, that means you’ll be dealing with OAuth 2. 0 JWTs, a registration JSON file, and a handful of well‑defined endpoints (launch, token, and a few data‑pull routes).
The LTI Piece
LTI isn’t a new buzzword; it’s the glue that lets a quiz from one vendor appear inside Canvas, Blackboard, or Moodle as if it were native. The Highlander API simply extends that glue with extra data—grade pass‑back, detailed analytics, and adaptive testing hooks.
If you’ve ever used a “single sign‑on” button that says “Launch in Blackboard,” you’ve already seen LTI in action. The Highlander version just adds a few more moving parts, which is why many admins feel like they need a PhD to set it up.
Why It Matters / Why People Care
Because learning isn’t a closed box anymore. Instructors want the best tools, not just the ones that happen to be bundled with the LMS. Highlander gives you:
- Rich assessment data – granular item‑level statistics that go far beyond a simple pass/fail.
- Seamless grade sync – scores flow back to the gradebook automatically, no manual CSV uploads.
- Adaptive testing – the API can request the next appropriate question based on a student’s prior answers.
When you get it right, students get a smoother experience and faculty get data that actually informs instruction. Miss the setup, and you end up with duplicate logins, missing grades, and a lot of support tickets Most people skip this — try not to..
Real‑world example: a mid‑size university swapped out a clunky legacy quiz tool for Highlander. Within a semester, faculty reported a 30 % drop in time spent reconciling grades, and the analytics team could spot at‑risk students two weeks earlier than before. That’s the kind of impact that makes the headache of configuration worth it.
How It Works (or How to Do It)
Below is the step‑by‑step roadmap most admins follow. I’ve broken it into bite‑size chunks so you can tick them off as you go.
1. Register the Tool with Your LMS
-
Gather the basics – you’ll need the tool’s client ID, deployment ID, and the public key that Pearson provides Nothing fancy..
-
Create a new LTI 1.3 tool in your LMS admin console Worth keeping that in mind..
- In Canvas, it’s Settings → Apps → “+ App”.
- In Blackboard, go to System Admin → LTI Tool Providers → “Add New”.
-
Paste the registration JSON – Pearson typically gives you a file that looks like:
{ "client_id": "highlander-12345", "deployment_id": "dept-67890", "auth_endpoint": "https://tpi.pearsoncmg.That's why com/. That's why bb. com/highlander/api/auth", "token_endpoint": "https://tpi.pearsoncmg.Plus, bb. Also, pearsoncmg. bb.com/highlander/api/token", "jwks_uri": "https://tpi.well-known/jwks. -
Save and note the tool URL—that’s the launch endpoint you’ll use later.
2. Set Up OAuth 2.0 Credentials
LTI 1.3 uses JWTs signed with a private key. You have two options:
- Pearson‑generated keys – they give you a PEM file; you upload the public part to the LMS.
- Self‑signed keys – you generate a key pair, then share the public side via the registration JSON.
Whichever route you pick, make sure the key length is at least 2048 bits. Short keys cause the LMS to reject the launch with a “invalid signature” error, and that’s a common stumbling block.
3. Configure the Launch URL
The launch URL tells the LMS where to send the student when they click the tool. For Highlander, it usually looks like:
https://tpi.bb.pearsoncmg.com/highlander/api/lti/launch
Add any required query parameters (often just context_id or resource_link_id). In most LMSes you’ll see a field called “Launch URL” – paste it there.
4. Map Grades (Optional but Recommended)
If you want automatic grade pass‑back:
- Enable Score Publishing in the LMS tool settings.
- In Pearson’s admin portal, map the outcome service URL to your LMS’s grade endpoint.
Example:https://yourlms.edu/api/lti/grade.
Make sure the score max matches what you expect (usually 100). Mismatched scales cause the LMS to truncate or reject grades.
5. Test the Integration
Never skip the test phase. Most LMSs have a “Test Launch” button that simulates a student session. Look for:
- A successful redirect to the Highlander interface.
- The student’s name and ID appearing correctly (check the JWT payload if you can).
- Grade submission showing up in the gradebook after you finish a mock assessment.
If anything goes sideways, the LMS logs and Pearson’s debug endpoint (/highlander/api/debug) are lifesavers.
6. Deploy to Real Courses
Once the test passes:
- Add the tool to a real course module or content area.
- Communicate to instructors that the tool is live and how to access it.
- Keep an eye on the first few weeks for any “missing grade” tickets.
Common Mistakes / What Most People Get Wrong
- Using LTI 1.1 instead of 1.3 – The Highlander API only speaks the newer spec. If you try to register it as a “basic LTI” tool, the launch will fail silently.
- Mismatched client IDs – The client ID in the registration JSON must match exactly what you entered in the LMS. A stray space or case change throws a 401.
- Forgetting the JWKS endpoint – The LMS needs the public keys to verify JWTs. If the
jwks_uriis wrong, every launch looks “untrusted.” - Skipping the “Redirect URI” whitelist – Some LMSs require you to list every possible launch URL. Forgetting one means the student gets a “invalid redirect” error.
- Assuming grade pass‑back works out of the box – You still need to enable the outcome service on both sides and map the correct line item in the LMS.
Seeing these errors pop up in the LMS console is frustrating, but once you know the pattern, fixing them is a quick edit rather than a full rebuild.
Practical Tips / What Actually Works
- Keep a sandbox copy of the registration JSON – Store it in a secure, version‑controlled repo. When you need to tweak a key or endpoint, you have a single source of truth.
- Use a JWT debugger – Chrome extensions like “JWT.io” let you paste the token and see the payload. Verify the
sub,iss, andaudfields match your expectations. - Automate token refresh – The access token expires after an hour. Set up a small script (even a Bash
curlwith a cron job) that hits the token endpoint and stores the fresh JWT for your monitoring tools. - Document the grade mapping – Create a one‑page cheat sheet that lists the LMS line item IDs and the corresponding Highlander assessment IDs. It saves the help desk a ton of time.
- Run a “pilot” with a single instructor before rolling out campus‑wide. Their feedback will surface edge‑cases (e.g., mobile device quirks) you might miss in a sandbox.
FAQ
Q: Do I need a separate LTI key for each course?
A: No. One client ID can serve multiple courses as long as the deployment ID is consistent. If you want course‑specific analytics, create separate deployments within the same registration.
Q: My students get a “Missing required parameter: iss” error. What’s wrong?
A: The LMS is sending a JWT without the issuer (iss) claim, usually because the registration JSON wasn’t fully uploaded. Double‑check the issuer field in your LMS LTI settings Worth knowing..
Q: Can I use Highlander with a non‑Pearson LMS like Canvas?
A: Absolutely. As long as the LMS supports LTI 1.3 (Canvas, Blackboard, Moodle, D2L all do), the integration steps are the same.
Q: Is there a way to see real‑time analytics from Highlander inside the LMS?
A: Yes. Pearson provides an LTI‑compatible dashboard that can be embedded as a “Tool Consumer” view. You’ll need to enable the Analytics scope in the registration JSON.
Q: What if my institution uses a proxy that rewrites URLs?
A: Make sure the proxy forwards the exact https://tpi.bb.pearsoncmg.com host unchanged. Any alteration will break the JWT signature verification Easy to understand, harder to ignore..
That’s the whole picture, from the moment you stare at a cryptic URL to the day your students breeze through a Highlander‑powered assessment without a hiccup Worth keeping that in mind..
If you’ve followed these steps and still hit a wall, take a breath, check the logs, and remember: most integration bugs are just a missing character or an outdated key. Consider this: once you get past that, you’ll have a powerful, data‑rich tool at your fingertips—and your students will thank you for the smoother experience. Happy launching!
As you refine your integration strategy, it’s crucial to double‑check each endpoint and parameter. In real terms, creating a concise grade mapping cheat sheet accelerates onboarding for support teams, turning complex data into actionable insights. Before scaling up, running a pilot with a single instructor offers invaluable real‑world feedback, helping you catch nuanced issues such as mobile compatibility or deployment variations. Automating token refreshes not only maintains access continuity but also reduces manual overhead, making your monitoring pipeline more reliable. Leveraging tools like JWT debuggers ensures transparency in token structure, which streamlines troubleshooting. This iterative approach builds confidence and ensures a smoother transition across the campus Most people skip this — try not to..
To keep it short, maintaining a single source of truth for token configurations, automating refresh workflows, and documenting mappings are key pillars for successful LTI integration. Each step reinforces reliability and efficiency, ultimately empowering educators and learners alike Still holds up..
Concluding this journey, remember that meticulous attention to detail and proactive automation are what transform integration challenges into seamless learning experiences The details matter here..
