PowerShell, API and "Put"

[tfra]

Hi

I'm having trouble getting powershell invoke-webrequest to work with the api, when I want to make "put" requests. Get/post request works fine.

"Put" request give me "status OK" / 200, but does not change any data.

Does anyone have a working example in powershell, where they are using "put" to change e.g. course publish/unpublish state or similar?

Best regards

Tommy

@This is what I just got working in my environment:

$access_token="accessTokenHere"

$url = "URLGoesHere/api/v1/courses/canvasCourseIDGoesHere/?access_token=$access_token&course[event]=claim"

Invoke-RestMethod -Method Put -Uri $url -ContentType 'application/json'

Example:

$access_token="6589~bpboeFDztrlyoh2nb4ktio257nm90qido3wjnmxcksHDE213"

$url = "https://institution.test.instructure.com/api/v1/courses/771/?access_token=$access_token&course[event..."

Invoke-RestMethod -Method Put -Uri $url -ContentType 'application/json'

course[event]=claim will unpublish the course, remember if a course has graded student submissions then you will be unable to unpublish the course.

I realise this is an old thread, but I'm posting here in case anyone else has the problems I had. 

I couldn't get the Canvas API PUT to work for updating a course. I finally managed to solve the problems. You need to pass a Powershell Hashtable object in the BODY parameter, and use 'multipart/form-data' as the CONTENTTYPE. The following code works for me. Hope it helps someone else. 

$token = "<YOUR_TOKEN>" 
$headers = @{"Authorization"="Bearer "+$token}
$URI = "https://<HOSTNAME>:443/api/v1/courses/<COURSE_ID>"

$body = @{
    'course[sis_course_id]'='NEW_SIS_ID'
}

$response = Invoke-RestMethod `
    -URI $URI `
    -Headers $headers `
    -Method PUT `
    -Body $body `
    -ContentType 'multipart/form-data'

Write-host $response
