In VBCS I am using Rest service of your internal Fusion to practice get the data by using BOP process.

But i heard that we can use specific rest service of Fusion

with Username and Password i.e it will work for that fusion instance only.

Is there any way how can i pass the username and passowrd in rest service URL or how can i make that rest service work in DEMO VBCS.
