WebService giving access denied when called from Portal

We are moving our code from development to SIT…

The webservice gets called fine in development environment…

But it gives access denied issues when moved to other environment…
What all configurations we need to take care of while moving to other environment for the webservice connectors?

Hi Sunny,

Update the End point URL, User name and password in CAF runtime of MWS.
I believe these are enough.
