Hi all, I've deployed an LTI 1.3 tool as a Discussion Topic Menu, and when I click the menu item in my course, I get back a json result, but I can't find the Discussion Topic ID in the json results.   

Does anyone else have experience working with LTI1.3 and Discussion Topic Menu placement ?

Thanks

I recently updated my Canvas LMS Mods (Basic) Chrome extension to provide some new enhancements to the course search and admin flyout menu inspired by ideas and requests I have seen from other users in the community.

It's few months that I don't access the Canvas app installed on OVH VPS server. I tried now and it shows the directory of files, but not the login interface. Nothings has been changed since the last time I use it (december 2022)

Hi all,

I would like to attach a zip file to all of my students submissions. I have been able to upload the file via the Cavnas API. However, I cannot seem to get the file to attach a student's submission. Acccording to https://canvas.instructure.com/doc/api/submission_comments.html I need to "PUT" the file id to the submission API. Can someone who knows rest API better assist me? The main issue is not really understanding how to use the "parameters" for a submission comment here https://canvas.instructure.com/doc/api/submissions.html#method.submissions_api.update 

I've attached a portion of my script below, but a linux command would be sufficient too.

I need an access token to grab a list of line items during the LTI1.3 workflow. I am currently receiving an unsupported grant type error.

I have seen claims that Canvas does not support this flow to issue access tokens for machine to machine API use.

I'm a teacher, and I've been playing with the api in a few other sheets that I've found. It's got me wondering if I could use a google sheet with a series of my gradebooks brought from other sheets, and have it update the grades in canvas.

I have a suggestion for a couple new features that I know i would use frequently. I believe other students would as well. It is efficient and time saving, also would help navigate us through what we have completed over our time in school, our past and current classes. Maybe the instructors would find it useful and a helpful added feature for them as well. 

Unsure of how Canvas is programed but I sure am hoping it can be tested, figured out and added into a feature update. 

Dear Canvas 

This is Wasta, I am using Canvas app which my school provides me to takes the video lecture but on my Ipad (IOS 15) generation 8 ,as I open the video there is no audio in the video , only when I start the video there is a sound but as soon as I forward it or rewind the video the audio disappears. I contacted the apple support system they said my device is working fine and everything is good to go from my side they asked me to contact the developer as this issue is specifically for canvas. 
Also I tried to take the video from safari, chrome, Firefox but I faced the same issue there as well no audio as soon as I forward or rewind the video. Please help me in fixing the problem I am so worried due to this.

Regards

My team is trying to replicate in one of our views how Canvas presents TODOs in its own UI. The TODO items endpoint (https://canvas.instructure.com/doc/api/users.html#method.users.todo_items) appears to be the correct one to use, although it's unclear what parameters Canvas itself may be using to for its presentation. As such, we have some questions about Canvas and the API.

When Canvas presents the TODOs in its own UI, what rules/boundaries determine the list of items that are being presented:
1. Does it present the user's most recent n number of TODOs?
2. Does it present the user's TODOs for the current term?
3. Does it present all of the user's TODOs ever?
4. Something else?

Regarding the TODO items API (https://canvas.instructure.com/doc/api/users.html#method.users.todo_items), we're trying to understand some nuances of the pagination. Specifically, what is the difference between fetching the "current" vs "last" pages?

I want to know how to use the webhook subscription api, including all the context types and such.

I need an api endpoint that returns a course image url.

Learn about the Chrome extension that I've been developing as a personal side project to use with Canvas LMS to add some new features and help improve workflows.  Most of the customizations so far are for the admin area of Canvas, but I am now working on adding some customizations that will add features in other areas of Canvas that could be useful to more users.

“Computer Vision” sounds like something from the future, though computer vision algorithms are not as fantastic as they seem to be. Starting from 1960-ies and up to today, computer vision was developing along with AI ideas and culminated in today’s helping hand of business and marketing enhancement. Let’s discover why, in the era of tech, it becomes essential to get to know such technologies.

Hi Everyone,

Great to be part of this community, Im IT Support for Horizon Christian School, and would love to share an app i made for the school.

Not sure were to post this, so hopefully ok here.

I have created an application with a Settings file that will make this application universal across platforms.

Our host of example is horizon-sa.instructure.com the key you need to generate in your user settings

Click [+ New Access Token]. button

I have shared from my onedrive, feel free to try it out if you like.

I want a test question type that I will call a mastery question. This kind of question will allow me to randomize the input numbers so that the answer can be calculated by Canvas but will be different every time for every student.

For example, ...
If I want to test that students know that the sum of the three angles in any triangle is 180 degrees then I would have Canvas randomize a variable 'A' (I could tell Canvas to generate a whole number between 20 and 50) and a variable 'B' (I could tell Canvas to generate a whole number between 50 and 90). Then the answer could be automatically calculated by Canvas as '180 - A - B'.

Students could answer this question only if they understood the principle but could test their knowledge using the same question an unlimited number of times. That is because the first time they are asked the question: "What is the third angle of a triangle if the first angle is 32 degrees [random number generated for 'A'] ad the second angle is 76 degrees [input random number generated for 'B']? The correct answer would be calculated by Canvas as 72 degrees (180-32-76 = 72). If the student did not enter the correct answer they would get feedback reminding them of what they need to know then they could get the same question again but with different numbers.

I want to use this for a math review test that should evaluate the students' readiness for moving forward in a course. This is essential for any math-rich course.

Unenroll user from a class via SIS UserID?

I'm looking to build an app that integrates on all canvas pages for the student role and ideally would like to use LTI to accomplish this, but as LTI placement doesn't allow for space on every page and doesn't allow for the space I'm looking to occupy (right sidebar) I am currently building this app out using the global javascript functionality. I do still need to authenticate the user on my server for server side functions and this is where LTI really would have helped. I'm curious if anyone has any experience combining these two approaches and if there might be a way  to authenticate a global js based app using the LTI 1.3 protocol (from the global js context - so would have to be an api call or something).

If not (maybe I'm approaching this the wrong way), I know I can call the canvas api using the context of the currently logged in user, is there an easy way I could maybe pass a token or something that my server could authenticate the logged in user?

Hi everyone, I hopefully have a simple question to ask here about this call.

I want to run a creation of quiz questions through a CSV file with this API and I have everything sorted bar how to write the say 4 possible answers to a multiple choice question. I'm using Postman to run the call.

If someone has an example that would be great too 😊

*FYI I have attached an image of a test question

Thanks again,

We need to embed our Hubspot chatflow to our Canvas Instructure.

Hi everyone this is what I currently have:

And my CSV contains the following two copies:

But my two copies are sitting as 'pre processing' and I am unsure as to what I'm doing wrong. Help would be greatly appreciated

Following on from our CanvasCon 2018 talk, this article describes how we embraced the web’s shift to a decentralised stack (APIs, no-code, Notion, Zapier...) and created our own authoring system that creates engaging and responsive pages rendered in Canvas.

گلاب با تقطیر گلبرگهای گل رز با بخار ایجاد می شود. گلاب معطر است و گاهی اوقات به عنوان یک عطر طبیعی ملایم به عنوان جایگزینی برای عطرهای پر از مواد شیمیایی استفاده می شود.

هزاران سال از گلاب استفاده شده است ، از جمله در قرون وسطی. تصور می شود که در ایران کنونی ریشه گرفته باشد.

به طور سنتی هم در محصولات زیبایی و هم در محصولات غذایی و آشامیدنی مورد استفاده قرار گرفته است.

This is a general question about APIs. Imagine, we have an object (users, assignments, etc) in canvas with all parameters set especially (SIS ID, or integration ID). Now, I want to know, if I send an API(POST request) with exact parameters to canvas, what would happen when the object exists already in canvas?

The canvas ignore the POST request? or overwrite the object with the new request, or create a duplicate?

I am asking this question because I am developing a python code, reads the data from the database and sends POST requests to create an object in canvas, so I am worried if I send a request which the object is already into the system.

Hello,

We are trying to set up Diffing mode to run our SIS files and are using the below CURL command.

/usr/bin/curl --tlsv1.2 -H 'Content-Type: application/octet-stream' -F diffing_data_set_identifier=DiffID -F attachment=@/home/batch/Canvas/canvasfiles.zip --output /dev/null --write-out '%{http_code}' --stderr /tmp/CANVAS.07072021.7995592.err.canvasfiles.zip -H "Authorization: Bearer TOKEN" https://oursite.edu/api/v1/accounts/1/sis_imports.json?import_type=instructure_csv&extension=zip 

Unfortunately the files are not updating anything in the system. Does anyone see anything wrong with our CURL command that may be causing this issue to occur?

Thanks,

Robert
