Hi All,

I am trying to get data using a client provided API. Postman shows data is coming from client app. I have created a batch job using Sys operation framework. Now, I am trying to info the same data that postman is showing me in its grid. After I hit OK button on my batch job, I get The Remore Server Returned an Error (403) Forbidden error. Can you please guide me what is the issue ?

I have tried to debug my code. The below mentioned code is what I received from debugger's StackTrace. Can you help me understanding what information it conveys. 

Name Value Type

    Sorry. I do not know what It is looking like this. Earlier, It was fine while I was writing.

    Hi,

    While trying from postman, you would have passed the token or authentication keys ? Have you passed such authentication in your class?

    Hi Anitha,

                    Yes, It is using basic authentication and I have used username and password in my code. Let me share my code as well.
