    dbms_output.put_line('exception');
END;

its not working and giving the below error

GET_RESPONSE' is not a procedure or is undefined

Answer 1

The issue is that GET_RESPONSE is a function not a procedure, therefor you need to return it back into a variable see https://docs.oracle.com/database/121/ARPLS/u_http.htm#ARPLS70993 for a more detailed description.

You will need to declare a response variable

resp  UTL_HTTP.RESP;

then your call to get response would look like

resp := UTL_HTTP.GET_RESPONSE(req);
