Where i can check return value from Consume REST in service center?
bcoz structure REST cant show anything.
As far as i know you can't see any response from any Service unless you write it yourself.
On the Rest Service that you are consumig you have 2 Systems actions that you can use: On Before Request and On After Response. On this 2 actions you can log to service center what you are sending and receiving when you call your actions.
Hope it helps.
Can you explain what are you trying to see exactly?
Are you just trying to see what is going on payload?
Are you trying to understand why something is not going in payload?
Let me know if I can help you.
