Rest API - add custom permission does not work (powershell)

jankowalewski

Hello,

I am new to the Rest API, so maybe it's just a beginners mistake. I am able to create new objects, change group members, etc. but I have not been able to figure out how to use endpoints that require lists in the form data. For example, if I create a folder and want to add a custom permission, I get the following errors:

## Get ticket

$Cred = Get-Credential

$Body = @{
   username = $Cred.UserName
   password = $Cred.GetNetworkCredential().Password
}

$BaseUrl = 'https://blabla.bla.de/cs/llisapi.dll/api/'

$Url = $BaseUrl + 'v1/auth'

$ticket = Invoke-RestMethod -Method 'Post' -Uri $Url -Credential $Cred -Body $Body -ContentType 'application/x-www-form-urlencoded' -SessionVariable OTSesh

# Create authentication header

$Headers = @{
    otcsticket = $ticket.ticket.ToString()    
}

# Create new folder - works fine

$Body = @{
    type = 0
    parent_id = 105119060
    name = 'Test'
}

$Url = $BaseUrl + 'v2/nodes'
$newFolder = Invoke-RestMethod -Method 'Post' -Uri $Url -Credential $Cred -Headers $Headers -Body $Body -ContentType 'application/x-www-form-urlencoded' -SessionVariable OTSesh

# Add custom permission - fails

$Url = $BaseUrl + 'v2/nodes/{0}/permissions/custom' -f $newFolder.results.data.properties.id

$Body = @{
    'right_id' = 11371;
    'permissions' = 'see', 'see_contents' 
}

Invoke-RestMethod -Method 'Post' -Uri $Url -Credential $Cred -Headers $Headers -Body $Body -ContentType 'application/x-www-form-urlencoded' -SessionVariable OTSesh

-> This one (above) results in: error: one or more parameters are invalid

$jsonBody = $Body | ConvertTo-Json
Invoke-RestMethod -Method 'Post' -Uri $Url -Credential $Cred -Headers $Headers -Body $jsonBody -ContentType 'application/json' -SessionVariable OTSesh

-> using json above, I get: error: required parameter permissions missing

Might this be a powershell thing or am I using the parameters in a wrong way?

check out the API spec at https://knowledge.opentext.com/knowledge/llisapi.dll?func=ll&objId=67789539&objAction=browse&viewType=1, looking at the example you may have to amend the $Body section :

Node ID = 8688
User ID = 9349

POST api/v2/nodes/8688/permissions/custom
body = {"permissions":["see","see_contents"],"right_id":9349}
