I've registered a new application in Cisco API Developer Portal. I can successfully generate an access token but I receive an "Access Denied" message (403 Forbidden) when I access the following endpoint: https://apx.cisco.com/cs/api/v1/customer-info/customer-details. I'm trying to obtain the customerId for my customer so I can access the other Services API endpoints. Credentials are working fine for other APIs such as serial number to info and eox that i have added to the application
