Can anyone help me out to download the attachment by using Rest API in Archer?

[AbhishekRai]

I am working on one request where I need to download all the attachment from an application. I tried by using GetAttachmentFile , but still it doesnot works.

Abhishek Rai‌,

I've moved your question to the RSA Archer Customer/Partner Community" data-type="space‌ space where it will be seen by the product's support engineers, other customers and partners.  Please bookmark this page and use it when you have product-specific questions.

Alternatively, from the RSA Customer Support" data-type="space‌ page, click on Ask A Question on the blue navigation bar and choose Ask A Product Related Question.  From there, scroll to RSA Archer Suite" data-type="space‌ and click Ask A Question.  That way your question will appear in the correct space.

Regards,

Erica

Abhishek, can you post the SOAP call you're using?

Hi David,

I used below SOAP as a reference:

<soap:Body>
<GetAttachmentFileResponse xmlns="http://archer-tech.com/webservices/">
<GetAttachmentFileResult>string</GetAttachmentFileResult>
</GetAttachmentFileResponse>
</soap:Body>
</soap:Envelope>

Additonally, I also tried record.GetAttachmentFile($session_token, 436); but it is  returning "</File>"

It would be great if you could provide me some reference related to powershell? 

Thanks for the help!!

Thanks, the link I posted in my initial response is to the doc that tells you how to construct the SOAP request to get the file and what's expected when successful.

SOAP Request

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
     <soap:Body>
          <GetAttachmentFile xmlns="http://archer-tech.com/webservices/">
               <sessionToken>string</sessionToken>
               <fileId>int</fileId>
          </GetAttachmentFile>
     </soap:Body>
</soap:Envelope>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

To download Attachments using REST API, check out the attachment sections in the  Content  segment.  

REST API call to download:

Verb: GET

URL: /api/core/content/attachment/*attachmentid*

Sample Response for /api/core/content/attachment/23

The following PowerShell shows how to download attachments to disk using a list of file ids:

$body = '{"InstanceName":"' + $instance_name + '","Username":"' + $username + '","UserDomain":"' + $user_domain + '","Password":"' + $password + '"}'
$response_login = Invoke-RestMethod -Method Post -Uri $login_url -Body $body -ContentType "application/json" 
if ($response_login.IsSuccessful) {
    $session_token = $response_login.RequestedObject.SessionToken
} else {
    Write-Warning "Unable to login with specified credentials"
    exit
}

# Create headers
$headersGET = @{}
$headersGET.Add("Authorization", "Archer session-id=" + $session_token)
$headersGET.Add("X-Http-Method-Override", "GET")
$headers = @{}
$headers.Add("Authorization", "Archer session-id=" + $session_token)

# Get list of attachment file ids, loop thru them and save to disk.
$fileIds = @(23,24,999)
foreach($fileId in $fileIds) {
    try {
        $api_url = $base_url + "/api/core/content/attachment/$fileId"
        $results = Invoke-RestMethod -Method POST -Uri $api_url -Headers $headersGET -ContentType "application/json" 
        if($results.IsSuccessful) { 
            $bytes = [System.Convert]::FromBase64String($results.RequestedObject.AttachmentBytes)
            $filename = $results.RequestedObject.AttachmentName
            $filepath = "c:\temp\download\" + $filename
            [IO.File]::WriteAllBytes($filepath, $bytes)
            Write-Host $filepath
        } else {
            Write-Warning ("Downloading File Id $fileid failed. " + ($results.ValidationMessages.Description | Join-String))
        }
    }
    catch {
        Write-Warning ("Unexpected error processing File Id $fileid. " + $_.Exception.Message)
