LTI 1.3, eduappcenter, and keys and secrets

[JeremyWayfinder]

We've set up an LTI 1.3 integration, since as far as I know, 1.1 has been deprecated.

I'm now working on adding the app to the Edu App Center, so that it will show up when you go to "Apps" in Canvas (I think).

However, when clicking on most of those apps to install them, it asks for a key and secret. Am I correct that that's an LTI 1.1 construct? What would happen with 1.3? Could it still be installed as easily?

Thanks!

Hiya,

Yeah, the EduAppCenter only really supports installation of LTI 1.1 tools directly into Canvas. You can have a LTI 1.3 app shown in the EduAppCenter, but it can't be easily installed by Instructors/Admins.

For LTI 1.3 you need to have a Developer Key configured and enabled on the root account, then once that's setup you can add the LTI 1.3 tool by using the client ID. This is not a workflow that I'd expect Instructors to be able to do so if you want it to be easily installable LTI 1.1 is the only way to go for now.

There is LTI Dynamic Registration https://www.imsglobal.org/spec/lti-dr/v1p0 but this isn't currently supported by Canvas and I don't know if Instructure plan on supporting it. Also I don't know if the EduAppCenter will support installing tools that support it.

Thanks, that's what I figured. We're not going to go backwards, so I guess we'll just leave it in the apps listing but with directions.

HI Matthew; are there any examples of LTI 1.3 apps currently on the Edu App Store? I looked at the submit form to add our app, and I'm not sure how I would fill that form out for a 1.3 app.

@knighte I'm not sure what you'd put in for an app that only supports LTI 1.3, but something like Vevox supports both LTI 1.1 and LTI 1.3. It might be acceptable to have a placeholder for the LTI 1.1 configuration, I'm not sure.

Dynamic Registration is on the Canvas roadmap for Q3 - Q4 2023, and the code is being worked on now. For new tools, LTI 1.3 is definitely the way to go.

@ColinMurtaugh any update on Dynamic Registration?

Hi @SamuelBellows  - 

I'm not an Instructure employee -- just another customer! 🙂 

Might be worth checking with your CSM to see if they have any more info.
