How do we add attachments to Dropbox / Assignment Folders over the API?

Hey Mike,

In order to submit to an Assignment there are two API routes available, one is specific for group Assignments and the other is for an Individual.

The Group Assignment route:

http://docs.valence.desire2learn.com/res/dropbox.html#post--d2l-api-le-(version)-(orgUnitId)-dropbox-folders-(folderId)-submissions-group-(groupId)

The Individual Assignment route:

http://docs.valence.desire2learn.com/res/dropbox.html#post--d2l-api-le-(version)-(orgUnitId)-dropbox-folders-(folderId)-submissions-mysubmissions-

Both of the routes are POST and take a body that is of type multipart/mixed. This page has examples of what the body should look like for various file uploads. The Assignment route should be highlighted approximately half way down the page under the Upload to Dropbox heading:

http://docs.valence.desire2learn.com/basic/fileupload.html?highlight=https://someLMShost.edu/d2l/api/le/1.0/{orgUnit}/dropbox/folders/{folderId}/submissions/mysubmissions

Hope that helps,

Dave

Hey @Deleted Account​ ,

Based on your video, it looks like you have the Locker tool enabled. With the current user that you are performing the login with you could upload files to their locker using APIs. Here is the documentation for the Locker APIs:

http://docs.valence.desire2learn.com/res/locker.html#post--d2l-api-le-(version)-locker-myLocker-(path)

Uploading to the locker would allow you to choose a file within locker, within the dialog, instead of having to use the My Computer option.

I hope that helps,

Dave

Hey @Deleted Account​ ,

I don't believe you need the "FileDescription" part of the JSON in your provided example. I think it should just be:

{ "Description": "description", "IsPublic": false }

for the JSON portion of the body.

I hope that helps,

Dave

Hey @Deleted Account​ ,

I think the error is a result of the "path" parameter in the route which you currently have set to the name of your file. This I think can be blank if you want to simply upload it to the root folder of your locker so the URL would be:

/d2l/api/le/(version)/locker/myLocker/

If you wanted to add it to a folder you would add the folder with a trailing slash to the path, like:

/d2l/api/le/(version)/locker/myLocker/MyTestFolder/

* Note: In order to add it to the folder, the folder must already exist. You can create folders using this same API as described in the docs:

http://docs.valence.desire2learn.com/res/locker.html#post--d2l-api-le-(version)-locker-myLocker-(path)

Thanks for trying it in the API tool, after looking at the tool it appears that it doesn't support the multipart/mixed content type with a file and a JSON. I'm going to bring this up with the team here and see if we can address that issue at some point.

Hope that helps,

Dave
