Hello. Trying to get the code right with powershell to use the API to add a custom property to a device. The custom property is a CityCode that we are using. I am an Administrator in our instance so i should have access to do everything and i am also using Token Authentication for the API call. Basing my code off of the example given here REST API v1 Examples | LogicMonitor The response i am getting back when i run this is ERRMSG - Property name cannot be null or empty ... Status - 1007. code is as follows. account info details removed for obvious reasons. $resourcePath is the device i am attempting to POST to and $data is what i would like to add as a custom Property. <# Use TLS 1.2 #> [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 <# account info #> $accessId = $accessKey = $company = <# request details #> $httpVerb = 'POST' $resourcePath = '/device/devices/6101/properties' $data = '{"Type":"customProperties","Name":"CityCode","Value":"CMP"}' <# Construct URL #> $url = 'https://' + $company + '.logicmonitor.com/santaba/rest' + $resourcePath <# Get current time in milliseconds #> $epoch = [Math]::Round((New-TimeSpan -start (Get-Date -Date "1/1/1970") -end (Get-Date).ToUniversalTime()).TotalMilliseconds) <# Concatenate Request Details #> $requestVars = $httpVerb + $epoch + $data + $resourcePath <# Construct Signature #> $hmac = New-Object System.Security.Cryptography.HMACSHA256 $hmac.Key = [Text.Encoding]::UTF8.GetBytes($accessKey) $signatureBytes = $hmac.ComputeHash([Text.Encoding]::UTF8.GetBytes($requestVars)) $signatureHex = [System.BitConverter]::ToString($signatureBytes) -replace '-' $signature = [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($signatureHex.ToLower())) <# Construct Headers #> $auth = 'LMv1 ' + $accessId + ':' + $signature + ':' + $epoch $headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]" $headers.Add("Authorization",$auth) $headers.Add("Content-Type",'application/json') <# Make Request #> $response = Invoke-RestMethod -Uri $url -Method $httpVerb -Body $data -Header $headers <# Print status and body of response #> $status = $response.status $body = $response.data| ConvertTo-Json -Depth 5 #Write-Host "Status:$status" #Write-Host "Response:$body"
