Hi I want to test the api's of ISE with a sandbox of Devnet. I can authenticate myself, get the version info and get the sponsor portal id. But creating a guest user give me the following error: <h1>HTTP Status 401 – Unauthorized</h1><hr class="line" /><p><b>Type</b> Status Report</p><p><b>Description</b> The request has not been applied because it lacks valid authentication credentials for the target resource.
Maybe this api is blocked on the Sandbox? If so, are there other ways to test these kind of api's?
Regards,
