createrequest error using API example

[jcarlone]

Hello,

I'm using the PowerShell example for Fetch Request History Details found at https://documenter.getpostman.com/view/1797923/RWaLwo21?version=latest (Access Request > Request History > Fetch Request History Details) and I'm having some issues getting it to work.

I took the example call from the documentation and swapped the token, requestkey, URL, and path for my own environmental variables. However, all I receive in response is "The remote server returned an error: (412) Precondition Failed." with no other information.

Has anyone had success using this example call in PowerShell?

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Authorization", "Bearer {{token}}")

$multipartContent = [System.Net.Http.MultipartFormDataContent]::new()
$stringHeader = [System.Net.Http.Headers.ContentDispositionHeaderValue]::new("form-data")
$stringHeader.Name = "requestkey"
$stringContent = [System.Net.Http.StringContent]::new("387")
$stringContent.Headers.ContentDisposition = $stringHeader
$multipartContent.Add($stringContent)

$body = $multipartContent

$response = Invoke-RestMethod '{{url}}/ECM/{{path}}/fetchRequestHistoryDetails' -Method 'POST' -Headers $headers -Body $body
$response | ConvertTo-Json

Please validate the access provisioned to the account that is used to perform these operations. 

error: (412) Precondition Failed is indicating that the access is denied.

Hi Adarshk, 

The login being used for the API call has the ROLE_ADMIN  Sav role.

Mandatory parameters to API are not sent

Hi rushikeshvartak,

I understand there's some parameter or format missing from the call, my question is what that missing thing might be. The call I listed is from the Saviynt API documentation, so I'm not sure what else it might need without guessing.

Your PowerShell script appears to be mostly correct. However, the Invoke-RestMethod cmdlet in PowerShell expects the body to be directly passed as a parameter, rather than as part of the headers. Here's the corrected version of your script:

$headers = @{
"Authorization" = "Bearer {{token}}"
}

$body = @{
requestkey = "387"
}

$response = Invoke-RestMethod -Uri '{{url}}/ECM/{{path}}/fetchRequestHistoryDetails' -Method 'POST' -Headers $headers -Body $body
$response | ConvertTo-Json
