Is there a way to update redirect parameters

[tjones1]

Our custom lti external tool allows an instructor to choose the original redirect url with a visual interface.

Is there a way to update the redirect url using another POST from within the tool?

I don't want to do it manually.

Travis:

Just discovered your question, and noted that nobody had answered you yet.......................

Yes, you can update Redirect installations - these instructions are for course-level:

• Navigate to the course, and click on the course Settings link.
• Click on the "Apps" tab
• Click on "View App Configurations"
• Scroll down to the appropriate Redirect configuration, and click the down-arrow next to the gear on the right
• Choose "Edit" from the drop-down menu,
• In the Edit dialog box, update the URL
• Click "Submit"

I hope this helps

Our External tool is a resource_selection tool.

When an assignment is created and the tool is selected, the instructor picks the media to use for the assignment.

?media=##  (see image above)

If the instructor wants to change the media they can select another item from a user interface to set the media ##

The problem:

After the resource link has been set the first time, the launch_presentation_return_url changes to:

/courses/374381/external_content/success/external_tool_redirect

and no longer accepts an updated media=##

Still looking for the Answer.

I'm think I need to update the Assignment. external_tool_tag_attributes: {url: ... }

But, receiving back a parser error when I try to GET the Assignment.

Sorry Travis, but this one is beyond my meager skills. Although, I will be looking into it further because my curiosity is getting the best of me.

After finding that I needed to change the assignment, I figured out how to Edit an Assignment using the API.

Canvas LMS REST API Documentation

Kenneth Larsen helped me with my other question.

https://community.canvaslms.com/thread/2681?q=how%20to

To update the redirect url of an assignment created using an External Tool after the original resource selection.

I needed to PUT using curl.

$data = "assignment[external_tool_tag_attributes][url] = newURL";

     $ch = curl_init();

     curl_setopt_array($ch, array(

            CURLOPT_URL => $canvasapi."?access_token=".$atoken,

            CURLOPT_CUSTOMREQUEST => "PUT",

            CURLOPT_POSTFIELDS => $data,

            CURLOPT_RETURNTRANSFER => true,

     ));

     $result = curl_exec($ch);

     curl_close($ch);
