I am trying to integrate AmazonPay with my custom alexa skill.
With that, I am following the integration document and able to get the consentToken and proceed with setup. In setup, I have chosen "ChargeNow" type and build the payload to set the Connections.SendRequest directive. When it return back, it suppose to give "billingAgreementId", but it gives an error "Error code - 500 Internal error".
Help me to resolve this issue.
