Oracle API Platform's API Implementation has two service naming convention 1) API Request 2) Service Request.
API Request - is the endpoint to which users or applications send requests for your API.
Service Request - is the URL at which your back-end service receives requests.
In this blog we are going to discuss what are the additional configuration we need to done inside API Platform Gateway Server while invoking a HTTPS Service Request URL.
Since, its HTTPS URL obviously there is associated SSL cert with that URL which is signed by Certificate Authority.
Recently, I have been doing one POC where I was invoking a Service Request HTTPS URL but it was not working and later found out it's because of associated SSL certificate was not configured in Weblogic JKS Keystore.
Before, I get into detailed solution, let me tell you bit more about problem. At very initial stage when I tried creating an API which is in-turn calling an HTTPS service request, it was failing while invoking that service from rest POSTMAN tool and was getting "Internal Server error" as per below snap.
It was quite tricky to find out what's went wrong in back-end which was resulting above error. After struggling a bit I found one very important log file "Default.log" for API Gateway server aka Oracle Communication Service Gatekeeper (OCSG) Server, located at e.g. /u01/apics/install/domain/gateway1/servers/managedServer1/trace/ path. In your case "/u01/apics" might be different, but rest PATH should be same.
This logs, clearly state there was issue with SSL Handshake and was getting "javax.net.ssl.SSLHandshakeException: General SSLEngine problem" error as per given snap-
