I have to use PowerShell to manage a Websense server via API. I am using Invoke-RestMethod and I am using a json format to make the changes. The comand to the server is as follows:
Invoke-RestMethod -Uri $uriCreate -Method Post -Headers $headers -Body ($jsonCat | ConvertTo-Json) -ContentType "application/json"
My variables are as follows:
$uriCreate = https://<ipaddress>:<port>/api/web/v1/categories
$headers = #{ Authorization = <credentials> }
$jsonCat = [ordered]#{
"Transaction ID" = $transID
Categories = #(
[ordered]#{
"Category Name" = $catName
"Category Description" = $catDesc
"Parent" = $catID
}
)
}
When I attempt to create the category via Powershell I get the following error returned:
Invoke-RestMethod : {
"Error" : [ "Could not parse JSON: Value is not convertible to Int." ]
}
Any idea what I am doing wrong?

I have the following PowerShell API script:
$VMname = "abcd"
$IP_address = '2.2.2.2'
$url = "https://ansibletower.xyz.com/api/v2/job_templates/12321/launch/"
$token = "9998980fsfdfsdfdf"
$headers = #{Authorization = "Bearer $token"}
$contentType = "application/json"
$method = "POST"
#### $body = '{"extra_vars": {"vm_name": "abc", "vm_ip_address": "2.2.2.2"}}'
$body = '{"extra_vars":{"vm_name":'$VMname', "vm_ip_address":'$IP_address'}}'
Invoke-RestMethod -ContentType "$contentType" -Uri $url -Method $method -Headers $headers -Body $body
When I try it with manually predefined values in the body (see the commented body line above) - it works. But when I try it with variables $VMname and $IP_address, I get the error:
Unexpected token '$VMname', "vm_ip_address":'$IP_address'}}''
expression or statement.
And if I remove single quotes before and after variables VMname and IP_address I get:
{"detail":"JSON parse error - Expecting value: line 1
column...Possible cause: trailing comma."}
It is obviously a problem with syntax and / or formatting but I cannot find the solution. Does anyone know?
Use ConvertTo-Json for this:
$VMname = "abcd"
$IP_address = '2.2.2.2'
$body = ConvertTo-Json -Compress -Depth 9 #{
extra_vars = #{
vm_name = $VMname
vm_ip_address = $IP_address
}
}
$Body
{"extra_vars":{"vm_name":"abcd","vm_ip_address":"2.2.2.2"}}
Btw, it is probably not even required to serialize your body to Json as Invoke-Restmethod is supposed to take care of that:
-body
When the input is a POST request and the body is a String, the value to the left of the first equals sign (=) is set as a key in the form data and the remaining text is set as the value. To specify multiple keys, use an IDictionary object, such as a hash table, for the Body.
I am using the Azure Management Rest API in Powershell , to create an NSG with some rule properties at the creation time. (yes I am aware that there is a PS module that can do that as well)
I have constructed the body of my PUT request as per the Microsoft documentation.
$url = "https://management.azure.com/subscriptions/$subid/resourceGroups/$rg/providers/Microsoft.Network/networkSecurityGroups/$nsg2" +"?api-version=2022-05-01"
$body = #{
"name" = "NSG-Test";
"location" = "useast";
"properties"= #{
"securityRules" = #(
#{
"name" = "rule1"
"properties"= #{
"protocol" = "*"
"sourcePortRange"= "*"
"destinationPortRange" = "80"
"sourceAddressPrefix"= "*"
"destinationAddressPrefix"= "*"
"access" = "Allow"
"priority" = 130
"direction"="Inbound"
}
}
)
}
} | ConvertTo-Json
try{
$Result = (Invoke-RestMethod -Uri $url -Headers $Headers -Method PUT -Body $body -Verbose -ContentType "application/json")
Write-Host $Result
}
Unfortunately I am greeted with the following error when executing this code :
{
"error": {
"code": "InvalidRequestFormat",
"message": "Cannot parse the request.",
"details": [
{
"code": "InvalidJson",
"message": "Error converting value \"System.Collections.Hashtable\" to type 'Microsoft.WindowsAzure.Networking.Nrp.Frontend.Contract.Csm.Public.Se
curityRule'. Path 'properties.securityRules[0]', line 4, position 75."
}
]
}
}
So the reason behind this is the nested dictionary #{"name"="rule1"..} inside the securityRules attribute value.
When removing this hashtable, the request executes and the NSG gets created, however without any properties of course.
Is there any way to circumvent this issue and have the REST API accept my JSON body with it's properties?
I tried to reproduce the same in my environment I got the same error as below:
To resolve this issue, Make sure to add -Depth 4 in the ConvertTo-Json .
When I added ConvertTo-Json -Depth 4 the error was resolved.

I'm accessing some JSON data using Invoke-RestMethod and I want to iterate through it, performing another Invoke-RestMethod per id and using the apiHost value for each call. A simplified example of the data is below:
"items": [
{
"id": "1234",
"apiHost": "thishost.com"
},
{
"id": "5678",
"apiHost": "anotherhost.com"
},
Here is the function as i have it so far. The Write-Host line (for troubleshooting this) displays ALL the apiHost values per id and explains why the next lines don't work. How do I refer to the relevant apiHost per iteration through the id so that the next lines will work?
function Get-ID {$headers = #{
'Authorization' = $auth_string
'Org' = $organization
}
$response = Invoke-RestMethod -Method Get -Headers $headers -Uri $a_url
foreach($id in $response.items.id) {
$itemheaders = #{
'Authorization' = $auth_string
'Dept-ID' = $id
}
write-host $response.items.apiHost
$apihost = $response.items.apiHost + '/here/there'
$outfile = 'c:\temp\' + $id + '_details.json'
$response = Invoke-RestMethod -Method Get -Headers $itemheaders -Uri $apihost -outfile $outfile
}
}
This post seems to suggest what I'm doing is correct, but I think I'm missing something obvious.
I need to perform an Invoke-Webrequest with a specifically formatted body to add devices to a product. Here is what it looks like in json (example straight from the vendor's documentation):
$body_json = '{"datasource": [{
"parentId": "123456789000",
"name": "(name)",
"id": "(value)",
"typeId": 0,
"childEnabled": false,
"childCount": 0,
"childType": 0,
"ipAddress": "(ipAddress)",
"zoneId": 0,
"url": "(url)",
"enabled": false,
"idmId": 123456789000,
"parameters": [{
"key": "(key)",
"value": "(value)"
}]
}]}'
When I try to submit this in its json representation though, I get the following error:
Invoke-WebRequest : Can not deserialize instance of
com.vendor.etc.DataSourceDetail out of START_ARRAY token at [Source:
java.io.StringReader#22c614; line: 1, column: 1] At
C:\powershell_script_location\ps.ps1:114 char 9
+ $request = Invoke-WebRequest $url -Method Post -Headers $headers -Body $body_json - ...
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation:
(System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest],
WebException + FullyQualifiedErrorId :
WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand
The issue is with the format of the "parameters", parameter because the request submits fine when omitting the "parameters", but then the
devices that I'm adding are missing important parameter details.
Is there something wrong with Invoke-WebRequest, JavaScriptSerializer,
the vendor's code, or is this a user error? Let me know if any clarification is needed.
Unfortunately I don't know what a com.vendor.etc.DataSourceDetail instance looks like, as I am using an API and I don't have access to it directly.
Use Invoke-RestMethod instead of Invoke-WebRequest.
If you have the body as a string use:
Invoke-RestMethod -Uri http://your-url.com -Method POST -Body $body_json -ContentType "application/json"
If the body must be constructed from data/parameters, it might be easier to build a hashtable and convert it to json via ConvertTo-Json:
$body_json = #{
datasource = #(
#{
parentId = 123456789000
name = "name"
id = "value"
typeId = 0
childEnabled = $false
childCount = 0
childType = 0
ipAddress = "ipAddress"
zoneId = 0
url = "url"
enabled = $false
idmId = 123456789000
parameters = #( #{
key = "key"
value = "value"
})
})} | ConvertTo-Json -Depth 4
Invoke-RestMethod -Method 'Post' -Uri http://your-url.com -Body $body_json -ContentType "application/json"
Body Undefined
I couldn't understand why the req.body on the server was undefined (NodeJS Azure Function). It turns out I had a header that was an empty string.
It's not clear whether is was invoke-restmethod or azure-functions-core-tools that has a bug.
FWIW.
I'm writing a powershell script to call a RESTful API and I need to parse the response. I'm having trouble parsing the response because there isn't a key name to the array. The API just returns contents of an array:
[
{
"ProfileId": "b9b4bf0b-fea3-4464-af91-b79b521d36ba",
"SourcePhoneNumber": "8880001111",
"FirstName": "Peter"
},
{
"ProfileId": "b9b4bf1b-cta3-4464-af91-b68c521d36ba",
"SourcePhoneNumber": "8660001111",
"FirstName": "Fred"
}
]
Here's how I'm calling the API and getting the response:
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("content-type", "application/json")
$headers.Add("Accept-Language", "en-US")
$headers.Add("Authorization", "OAuth $AccessToken")
$response = Invoke-RestMethod "$($privateApiUrl)/api/v1/profiles" -Headers $headers -Method Get -ErrorVariable RestError -ErrorAction SilentlyContinue
if ($RestError)
{
$HttpStatusCode = $RestError.ErrorRecord.Exception.Response.StatusCode.value__
$HttpStatusDescription = $RestError.ErrorRecord.Exception.Response.StatusDescription
Throw "Http Status Code: $($HttpStatusCode) `nHttp Status Description: $($HttpStatusDescription)"
}
else {
Write-Host $response
#Need to parse the first ProfileId out of the response here
$json = ConvertTo-Json -InputObject #( $response )
Write-Host $json[0].ProfileId #This outputs nothing
$response | Out-File -FilePath c:\response2.txt
}
The 2nd to last line "Write-Host $json[0]... is where I'm looking to access the ProfileID.
The response is getting written to c:\response2.txt so I know the API request is working and I'm getting good data back from API call.
So what am I doing wrong in accessing the ProfileId of the objects?
As TessellatingHeckler stated - i just needed to not convert it to json and use $response[0].ProfileId
