Hi All, I’m attempting to retrieve the custom authentication token in the **Before Rule** and include it in the modified body. I used the following approach:

String accessToken = (String) appAttributes.get(“ConnectionID”);  
String customerID = (String) appAttributes.get(“CustomerID”);

However, the `customerID` value is returning as `null`. Could someone please assist me with this issue?

The response attribute mapped under Custom Authentication are not stored in the application schema. So it can’t be retrieved using _getAttributeValue_.

Instead you can refer to the CA attributes like **$application.ConnectionID$** and add it to the header or body of the operation.

I have resolved this using  
Map headers = requestEndPoint.getHeader();  
String connectionID = headers.get(“Authorization”);  
String customerID = headers.get(“X-Customer-ID”);
