Thanks so much for your response! It looks like your solution works for LTI 1.1. And it gave me the hope that the same would work for LTI 1.3, which it does. To those using the PHP library, all you need to do is to save the launch id and then you can use something like: $launch = LTI\LTI_Message_Launch::from_cache($launch_id, new LTIDatabase()); The 1.3 library will then handle the request for you and update the grade

Hi, Using LTI 1.3, is it possible to programatically change grades at a later date? Right now I have: $launch = LTI\LTI_Message_Launch::new(new LTIDatabase()) ->validate(); I then have a student work through an assignment, and then use this object in performing the grade passback within that session. This works great, but what if I need to change the students grade at a later date? Potential use cases: 1) An instructor removes a poorly worded question from the assignment so that scores have to be recomputed. 2) A grader has to do some manual scoring. Would I be able to just save the latest launch objects for each student associated with a particular assignment, then iterate over and send the scores back? In particular, I'm wondering if the launch objects might be time sensitive. Or I'm also wondering if there's there's a better, accepted approach. Thanks so much!

Thank you both for responding to this! And, I've figure out the issue after taking a closer look at the Assignment Selection placement type. What was happening is that I was creating them as modules. And, it looks like the resource_link_id was not generating different ones in this scenario. Maybe not a bug, but a little surprising! Enjoy your weekends...

Hi, I've (finally!) been able to successfully perform my first grade passback using LTI 1.3. However, for my particular use case, the app will consist of multiple assignments per course. I thought that I could just create new assignments and each time I launched a new app it would have a different resource id so that the grade would be correctly passed back to the correct assignment in the gradebook. However, after creating several assignments as an instructor, I can see that the resource id doesn't change. Does this mean that if an instructor wanted to create 30 assignments in a quarter using my app that the site admin would have to create 30 separate instances of the app, each going to the correct URL (i.e. each URL is specific to an assignment in my app)? I'm thinking that I must be missing something very fundamental and hoping that someone can help me to understand how I can create a single app but have some identifier so that when the app is created multiple times within a course, that the associated grade gets passed back to the correct assignment. Thanks so much!

Hi, I have an app where users cans create assignments and I'd like to pass the grades back to Canvas using LTI 1.3. I'm at the point that I can get my app to talk with Canvas and launch my app as an external tool. My thought was that there would be a unique deep link identifier id that I could then use to link up to my app's assignment ids. For example, an instructor would launch the app, choose which assignment from my site they want linked and I could then save the relationship in my database. Later on, I was hoping the instructor could pass back the scores to Canvas by a "Release scores" button and my app would then iterate over each of the assignment scores, and pass back to the appropriate resource using something like: $score = LTI\LTI_Grade::new() ->set_score_given($score_given) ->set_score_maximum(100) ->set_timestamp(date(\DateTime::ISO8601)) ->set_activity_progress('Completed') ->set_grading_progress('FullyGraded') ->set_user_id($launch->get_launch_data()['sub']); $score_lineitem = LTI\LTI_Lineitem::new() ->set_tag('score') ->set_score_maximum(100) ->set_label('Score') ->set_resource_id($launch->get_launch_data()['https://purl.imsglobal.org/spec/lti/claim/resource_link']['id']); $grades->put_grade($score, $score_lineitem); where the above code is from here My question is whether there is a unique identifier that is passed back with each external launch so that I can use the above concept and match up each of the assignment launches within a course with the assignments that I have in my app. Thanks so much.

With the help of a team member, we figured out how to move past this step. Though I can't explain why, one of our accounts was a "site admin" and one was just an "admin". When under "site admin" the LTI 1.3 option didn't exist, but it did under the admin account.

Hi, I'm at the finish line of my first LTI 1.3 flow. Canvas can do the OIDC authentication and send me back the information about the launch. However, for my tool, I can see that the JWT doesn't have an LTIDeepLinkingResponse which I would expect from my JSON config since I have a deep link request. Might I be setting this up incorrectly? And, to access the external tool, I'm creating an assignment, then choosing the tool. My LTI 1.3 config and a sample JWT follow: { "title": "Dev-Adapt try again", "scopes": [ "https://purl.imsglobal.org/spec/lti-ags/scope/lineitem", "https://purl.imsglobal.org/spec/lti-ags/scope/lineitem.readonly", "https://purl.imsglobal.org/spec/lti-ags/scope/result.readonly", "https://purl.imsglobal.org/spec/lti-ags/scope/score", "https://purl.imsglobal.org/spec/lti-nrps/scope/contextmembership.readonly" ], "extensions": [ { "platform": "dev-canvas.libretexts.org", "settings": { "platform": "dev-canvas.libretexts.org", "placements": [ { "text": "Embed Tool Content as a Canvas Assignment", "enabled": true, "placement": "assignment_selection", "message_type": "LtiDeepLinkingRequest", "target_link_uri": "https://dev.adapt.libretexts.org/api/lti/target-link-uri" } ] } } ], "public_jwk": { "d": "tkdUVHX4yVKzkK1pPLKO11QXzteTcBF4QJIVGJ6ZjwBf7WeBIXzMrGli2XFSFum2yygrbkQlTF_Xr3yG5JC1NBK4aj4t0AE3Fy_89a_PmwFKa4aTQIPX73zP2bpFw0YHnejDzTAtdZ7HhKfB1FOKBzcF1ci-hb5rLax8mKBJ5IyIjJN-DtjBYwGr6CCYTNIJKF1Z8UT-TDYtZxj1YSvk32cka4ttMdUYdwrCKt-j1MsQiAlpA-437SxqlXUAX7ooutNCz-b-57h8_Sw7AnmO8USbtHi3Q5O__bpG_H7quv_t1WDGAoWFr6cOA2h_Kgx8WX1szMmiOPPZmpdu5YYHcQ", "e": "AQAB", "n": "8osiSa75nmqmakwNNocLA2N2huWM9At_tjSZOFX1r4-PDclSzxhMw-ZcgHH-E_05Ec6Vcfd75i8Z-Bxu4ctbYk2FNIvRMN5UgWqxZ5Pf70n8UFxjGqdwhUA7_n5KOFoUd9F6wLKa6Oh3OzE6v9-O3y6qL40XhZxNrJjCqxSEkLkOK3xJ0J2npuZ59kipDEDZkRTWz3al09wQ0nvAgCc96DGH-jCgy0msA0OZQ9SmDE9CCMbDT86ogLugPFCvo5g5zqBBX9Ak3czsuLS6Ni9Wco8ZSxoaCIsPXK0RJpt6Jvbjclqb4imsobifxy5LsAV0l_weNWmU2DpzJsLgeK6VVw", "p": "-TEfpa5kz8Y6jCPJK6u5GMBXIniy1972X_HwyuqcUDZDyy2orr3rRj0sOtJoDHtC62_NnrhuvZYyW-cZ0nDzrzPj8ma-gCpbcgdRfOpEAeA6T_xjfN5KN3u3dHQ7e_qoBtCPJFhiB8Axmjs_NdbwUo0axqQB50QpbRv3gdid0qk", "q": "-SuCu0BGnaed3VYa7GBAyNf74eNPSn3Ht9MwK1-9iFmC5T0CULHndUcV4Zzp-qwORSYEW_R2oyfDRM_MRCosSUEiHztMZLglJeZxtBx6MjH6vLaQwW7Ixkg-69kKct8H93tC7YNTqZ14gEwT_wBfmQGqfV6R12KgRJ1KQeSSJ_8", "dp": "aPCeAjjZ7YHuP_wGCOUNUvYU-8hWkIAtwyPxIpMAdusTS6oTwlrqjK7QRIk9FhyGhv2TWwcSY7avyHIfNrcoeBzjHr7T9MdhsTiRwYgqUZvrEqoX_4rhOFJaZKlaL5DUV-JWlZi-18LBYNEYgoTcufcAUqzYvFrBE1jWt5DQjdk", "dq": "E7OrDJ9SdhjQ1LWAP3yE4tyhIAVXOa6kYhai0mspk2RwgyvFyReoE4_hXQuJPLbqEfGlmpfD4ba9K-26WxFymwA5cHrB2Zzt4wdLqlAuIVXuW4mb_I-D9Jm1z_RDbT3RZXIropglv12iL5LUae9fn7uP_YXCxmMYBRTi0D8Ah4U", "qi": "YwLEhy55SQucj2vQqSO1dqn2YiB2ARHBA83QKb1PHflkTNGn3mR_gLow-xU7BmTmA2-9CeDHiJrD181gb48XbI24Nn4QXAjS-mYYIpFASR739UI4W5wyyOCMyFtT6OupEgkqKw_swITU1GHKYI-lB_-y0Q-XSdLmuP6ZkkdAQao", "alg": "RS256", "kid": "58f36e10-c1c1-4df0-af8b-85c857d1634f", "kty": "RSA", "use": "sig" }, "description": "Looking to try it again!", "custom_fields": {}, "target_link_uri": "https://dev.adapt.libretexts.org/api/lti/target-link-uri", "oidc_initiation_url": "https://dev.adapt.libretexts.org/api/lti/oidc-initiation-url" } And a typical JWT response (decoded I can see that it starts with "https://purl.imsglobal.org/spec/lti/claim/message_type": "LtiResourceLinkRequest", which makes me nervous!)

I do appreciate the thought of posting this question (issue?) at the github repo and have done so. Regarding the Community Manager who doesn't think this is even possible, might there be a way to verify it? I'd hate to keep attempting this method of testing my tool if it has no chance of succeeding using my current approach. Thanks again!

Hi, I'm trying to create my first LTI Advantage Tool and have: 1) Installed Canvas locally via Docker 2) Successfully launched from my local Canvas install to talk with my tool However, when I redirect back to the authorization_redirect URL, (see example at bottom), I'm getting: while(1);{"errors":[{"message":"An error occurred.","error_code":"internal_server_error"}],"error_report_id":119} My question is how can I as the site admin view the error report so I can see what's going on?

According to my Admin View I was successful in creating a developer key associated with the external App: However, when I then click on Settings->Apps, it doesn't show up: I also clicked +App hoping to see the option of entering in the client id as described here, but the only options are: Manual Entry, By URL, Paste XML, and by LTI 2 Registration URL. If someone could please tell me how to input the Client Id I would appreciate it. Thanks so much! -Eric

Hi, I'm starting to dig into LTI Advantage and have a question on the big picture flow. In LTI 1.1, users of my external app would first have to log into my app inside of Canvas so that I could save the Canvas user id and associate it with the user id that I use within my own app. Then, once the connection was made, on future launches, I could just look up the Canvas user id in my database to see which user it is. However, if my external tool uses LTI Advantage, it doesn't seem to be the the same process. It looks to me, that now the identity of the user is never determined by my app; instead it's determined by Canvas, so that when Canvas passes back the Canvas user id, I should automatically create a user associated with this Canvas user id. Is this a correct understanding of the new flow? In other words, do users not even create accounts on my website to start? Thank you!

Hi, I'm trying to integrate OAuth2 to generate access tokens and can't seem to get past the first step. Through Berkeley's Canvas support, I've received the following email: I've created a production developer key with the requested endpoints (Assignments, Assignment Groups, External Tools) and learnbybyte.com as the redirect URI. The detail for the key is 10720000000000482 Based on the API docs, I think that the first step should be to visit: https://ucberkeley.instructure.com/login/oauth2/auth?client_id=10720000000000482&redirect_uri=https://learnbybyte.com&response_type=code which will then in theory have the user log in and post back to https://learnbybyte.com. Instead, I'm getting the message: {"error":"invalid_request","error_description":"redirect_uri does not match client settings"} Any ideas on how to troubleshoot this would be appreciated.

So, I figured out how to achieve what I wanted to achieve and am outlining the steps below hoping that it might help someone else out. First, to add an external URL to the assignment object, pass: assignment[external_tool_tag_attributes][url] = 'https://my_favorite_url.com' to your list of parameters. Your assignment will then contain the external tool URL. The tricky part was then how to create custom assignments: I needed the external URL to differ by a custom field to help in specifying a specific assignment to help with grade pass back. My solution was to create files which had names like: https://my_favorite_site.com/assignments/1.php which were created at the time of the assignment creation. Then, in that file I had something like: $the_get_variable_I_want = basename(__FILE__, '.php'); require_once(DOCUMENT_ROOT . 'the_place_where_I_do_my_LTI_stuff.php'); Then, my LTI file will be passed $the_get_variable_I_want. So, I'll have one external tool url for each assignment and then grades can be passed back accordingly. Finally, for those of you who need multiple custom variables, the "1" above could represent a record in your database, saved at the time of assignment creation by assignment id, and then used to look up any number of variables that you actually need. Or, as another alternative, your file could be something like 1-2-3.php and then you can pull out the 1, 2, 3 and use them accordingly. I hope that at least one of you will find this helpful.

Hi, I'm able to use the API to create Assignments as well as create External Tools, but am not quite sure how to link the 2 up with the API. For my particular use case, 5 different external tools will be associated with 5 different assignments. The urls to the external tools are identical but they have a custom field to differentiate them. According to the docs, I need to use: assignment[external_tool_tag_attributes] Hash of attributes if submission_types is ["external_tool"] Example: external_tool_tag_attributes: { %r/ url to the external tool url: "http://instructure.com", %r/ create a new tab for the module, defaults to false. new_tab: false} when I create my assignment. I then have 2 questions... 1) Since there are different possible hashing methods, how does Canvas know which one I'm using? I must be missing the boat on this one. 2) Since my external tools differ only in the custom field (differentiating for the purpose of grade passback), how would Canvas know which particular Tool goes with which Assignment? Perhaps there's a smarter approach to this? Thanks so much for your thoughts!

kreut · ‎05-20-2020

Thank you for the additional info...

kreut · ‎05-20-2020

Thank you! It worked once I took both of your suggestions... And I should have realized that it was performing some sort of GET since it looked like it was trying to load up the url instead of POST to it. Cheers, Eric
