Steps
- Read the Get started with Citrix Cloud APIs section to ensure that you have the
customerIdandbearer token. - Get the
siteidfrom How to get a site ID API. - Use the API in this document to get the raw icon base64 string from a file containing icon data.

$response = Invoke-RestMethod -Uri $requestUri -Method POST -Headers $headers -Body $jsonBody
return $response
}
$customerId = "customer1" #Replace with your customerId
$siteId = "61603f15-cdf9-4c7f-99ff-91636601a795" #Replace with your site ID
