In version 4.5 we have tried to make using of the WebAPI and the Web Client much simpler for desktop users. You no longer need to deploy the WebAPI manually (if you are going to use it on the same computer). To use it, just start the Toolbox WebSuite app that comes preinstalled with version 4.5. Once started, you'll have a link to access the WebAPI. You can copy the address and use it for your integrations.
If you have more specific deployment requirements or wish to use the WebAPI on a remote host, please contact the Toolbox Helpdesk and we'll make sure to help you with that too.
Many Thanks Stanislav
