Update LTI Quicklink via API request: JSON Binding Error

Matthew.Di.Giuseppe36

I am attempting to update an LTI 1.0 Quicklink via the API (Oauth 2.0, in Postman). The initial connection is fine and I can retrieve data via GET requests.

 

I am using PUT to send raw JSON to:

https://mysite.brightspace.com/d2l/api/le/1.52/lti/link/1234

 

My JSON: (as described by https://docs.valence.desire2learn.com/res/lti.html#LTI.CreateLtiLinkData)

{

"Title": "New Title",

"Url": "https://new-url.mysite.com/path/to/file/",

"Description": null,

"Key": null,

"PlainSecret": null,

"IsVisible": null,

"SignMessage": null,

"SignWithTc": null,

"SendTcInfo": null,

"SendContextInfo": null,

"SendUserId": null,

"SendUserName": null,

"SendUserEmail": null,

"SendLinkTitle": null,

"SendLinkDescription": null,

"SendD2LUserName": null,

"SendD2LOrgDefinedId": null,

"SendD2LOrgRoleId": null,

"SendSectionCode": null,

"UseToolProviderSecuritySettings": null,

"CustomParameters": null

}

 

And I always get this error:

{

"type": "http://docs.valence.desire2learn.com/res/apiprop.html#json-binding-error",

"title": "JSON Binding Error",

"status": 400,

"detail": "Provided JSON is invalid or does not match the expected format."

}

 

I assume that means my JSON is not what it's expecting for updating an LTI Quicklink, so I'm wondering what the correct information is? I only want to update the title and URL, nothing else. I tried only sending those 2 key/values but I got the same error.

 

Any help would be greatly appreciated!
