How to set multi-value attributes using REST API in PowerShell

Kinch · 2024-07-31T21:27:15+00:00

There was an error rendering this rich post.

I am trying to copy a set of attribute values from one Category to another using PowerShell and REST … I have it working for all attribute value types except multi-value, I just can't seem to get the syntax correct.

"/v1/nodes/36500965/categories/3310115"

$body = @{

3310115_16 = "Track 1"

3310115_17 = ["Signals","Tracks","","","","","","","",""]

}

$response = Invoke-RestMethod $URL -Method PUT -body $body -Headers $header -ContentType "application/x-www-form-urlencoded"

Of course the $URL has the server etc, and as I say if I don't have multi-value attributes, I can update using the above syntax but I can't seem to get the multi-value to work. I've tried with and without double-quotes, with and without specifying allowed values (in this case, 10), with and without the square brackets….all end up with the same error

Invoke-RestMethod : {"error":"The value \u0027[\u0022Signals\u0022,\u0022Tracks\u0022,\u0022\u0022,\u0022\u0022,\u0022\u0022,\u0022\u0022,\u0022\u
0022,\u0022\u0022,\u0022\u0022,\u0022\u0022]\u0027 specified for \u0027Discipline\u0027 attribute is not
valid."

I am certain that both values "Signals" and "Tracks" are valid entries, this is just a syntax issue I believe but I'm just not getting there. I'd welcome any information that might get me there (or verification that "that just won't work in PowerShell").

I tried it in Postman and it works with this payload MVA is in the square brackets

{
"1962212_2": "APPUS",
"1962212_3": [
"ONEs",
"TWOs",
"THreexx",
"Fourxx",
"Fivexx"
]
}

Postman code generator put this for PowerShell

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"

$headers.Add("otdsticket", "*OTDSSSO*gTwWPT-TJxPsBYA6dewAA")

$headers.Add("Content-Type", "application/x-www-form-urlencoded")


$body = "body=%7B%221962212_2%22%3A%22APPUSlast%22%2C%221962212_3%22%3A%5B%22ONExxx%22%2C%22TWOxxx%22%2C%22THreexxx%22%2C%22Fourxxx%22%2C%22Fivexxx%22%5D%7D"


$response = Invoke-RestMethod 'http://:8080/otcs/cs.exe/api/v1/nodes/1960342/categories/1962212' -Method 'PUT' -Headers $headers -Body $body
