Hello Brian. Sorry, I just tried this and I failed too. I would like to know how this is done as well. Do you have to email a contact and ask for a key?
Been exploring the use of LTI as well. Interesting and something to be pursued, IMHO!
Found a resource worth the time:
https://lti-examples.heroku.com/
KhanAcademy
Search for and embed Khan Academy lessons and exercise into course material. Khan Academy focuses on short lessons on math, science, etc. Uses the embedded player so students earn points for watching videos.
Config URL: https://lti-examples.heroku.com/tools/khan_academy/config.xml
any key and secret will work for this app. In other words, invent your own. For the working example below used: sossiglti for the key and the secret.
Have one working example of a Khan Academy video at:
http://sos.tcea.org/ltimoodle/course/view.php?id=4
Guest access is allowed.
A couple of other examples as well.

Hi Ken. I was working through those heroku examples myself trying to find good demos. I couldn't get the Khan academy one to work with that URL but I'll try again and if I don't , I will post back. Thanks
Here's my External Tool Config
Tool Name: KhanAcad
Tool Base URL: https://lti-examples.heroku.com/tools/khan_academy/config.xml
Consumer Key: sossiglti (one of your own invention)
Shared Secret: sossiglti (one of your own invention)
Launch URL:
https://lti-examples.heroku.com/tool_redirect?url=%2Fkhan.html
Secure Launch URL:
same
That will open a frame where one is browsing categories and videos available. Teacher does this … not the student.
Once one drills down to a video and one selects it, you will get a notice that from this time forward, anyone selecting the link you started to build will get the video … and then it shows the URL to that video you selected.
Once you return to your course, click the link just built and you'll see the video you had selected.
At first, one might have to use the .xml link above to find the tool_redirect?url ... hard to guess those. When the error page shows you copy the redirect link, go back to editing your tool and use the re-direct link in the Launch/Secure Launch URL.
Yeah, I know that's not very intuitive and it's strange, but ....

This was a great tool ... Have they disabled it.. I cant seem to get it working.. Still going for you?
Cheers.
Unless you are using Canvas there is no need to use the LTI tool to access this site - there is no LTI launch across to Khan Academy. Just try pointing your browser to https://www.edu-apps.org/lti_public_resources/?tool_id=khan_academy to see the interface.
Thanks Stephen,
I seem to be missing something here though. I get the main page but it no longer saves the navigated to page, just the main page even if I insert the full path.
I just get the message "You're not in a system that supports auto-inserting content, so you'll need to copy and past the following code by hand in order to insert it into your content."
I set it up a year or so ago and cant find my own example.
Any suggestions?
I don't know what you mean by "it no longer saves the navigated to page". Since this is just a normal hyperlink I don't think there will be any sense in which it will remember where you were last. However, you can set the hyperlink to point directly to a page of interest; e.g. https://www.edu-apps.org/lti_public_resources/?tool_id=khan_academy#/khan_academy/browse/root.new-and-noteworthy
Unless you have connected via Canvas there is no way of automatically returning a link to the selected resource and add it to a page in Moodle. Instead the page gives you options for copying and pasting the URL to the resource or HTML to use to embed it within a page.
I found the setup that I was looking for and it still works... Too many dev sites
I think this was Ken's original setup??
Settings are:
Tool Name: KhanAcad
Tool Base URL: https://www.edu-apps.org/tool_redirect?id=khan_academy
Consumer key (copied from Ken's post above): sossiglti
Shared Secret: (copied from Ken's post above): sossiglti
Make sure that "Show tool type when creating tool instances" is checked.
When you create the tool in a course page you are offered all the directories and when you navigate to the one you want it "saves the navigated to page" and then that's where the students are directed to when they access the resource.
Cheers,
Too many dev sites .... yeah, I know!

The above might help explain a little more but basically, there are some LTI resources that do not really require a consumer key or shared secret, but Moodle is looking for them.
Noticed just now in check things on ltimoodle, certificate issue with some of the links. That could be an expired CA cert, I hope. Otherwise, there's a serious problem given the state of https (ssl/tls/etc) today.

Here is a site that lists other LTI apps that may be useful.
