IDCS token call failed in PHP

Content

Hi,

We can retrieve IDCS access with cURL.

We are getting the following error when we do the same in PHP. Any idea how to fix it?

Thanks,

Adam

PHP code snippet

$token = json_encode(array("token" => $payload->{'access_token'}));

 

//Store basic auth in Configuration settings

$basicAuth = "a23NjcyMDk3MTE6NDFiMTU5YTYtZTQxMy00MjJhLWE4ZDQtODY4NjFlNjczOGQ2";

//Store IDCS URL in Configuration Settings

$curlAuth = curl_init();
