Hi Ailin,
for any SSL based communication (REST or SOAP) you need to configure the server certificate for the endpoint.
This is a self service option in BAWoC which you can access from "System Operations" main menu. When opening "System Operations" you'll see an entry called "Certificates". Here you can easily import a certificate by providing the URL you want to call in your service.
