Hello,

I am trying to call the external payment API service by sending the request header packer from Dynamics 365 CE custom workflow activity, but I am getting response as the Request Packet is Invalid 103 error, If I use request header packet uri as existing application then it's working fine.

Do we need to authenticate Dynamics URI at payment service, Any help or suggestion would be greatly apricated.
