Add content by external tool using API

[tapas sahu]

Hi,

I Am using "https://<canvas_url>/api/v1/courses/<course_id>/modules/<module_id>/items" for add the content to my canvas from a external tool.

but problem is when i am launch the external tool i am not getting module_id .

Please some one guide me how to get module_id.

Thanks in advance.

Why do you need the module_id in order to add content to canvas.  Are you using resource selection?  https://canvas.instructure.com/doc/api/file.link_selection_tools.html

Yes  i m  using resource selection.

You can use custom variable substitutions to get the module_id and module_item_id for the current launch.  In your tool configuration you need to add custom variables with the values $Canvas.module.id and $Canvas.moduleItem.id

You won't get this until after you add the item though.

Look at http://lti-tool-provider.herokuapp.com/tool_config.xml in the blti:custom tag

The resource selection variable is actually $Canvas.moduleItem.id instead of $Canvas.moduleitem.id. However, I don't think you will get the module item id during resource selection because the module item hasn't been created yet. You will only get module item id for a basic-lti-launch for a module item, not for creating one.

HI  Brad Humphrey,

Find the image in which i am getting user id but not getting module id.
Please suggest me how to get module id.

Resource selection happens during the creation of modules when you are using a tool to select the content for the module item.
