I have recorded a video tutorial about how to use the Blackboard Learn Web Services Framework. I wanted to be language agnostic so I have used SoapUI.
You will learn how to setup your Blackboard Learn environment to let an external tool to register, login and consume the SOAP webservices.
In this video we will get all the users with default system role. To this we will get a session, register a proxy tool with the required entitlements, login this tool and create the desired filter and the request to obtain the users.
Sorry for my english, it is not very "dynamic", but I think you can understand almost everything with the screen sharing.
