The parameterized URL method executes the Application Enabler context using parameters in a URL link. You can either make a GET request to the URL or direct the user's browser to it.
Example of a parameterized URL connection:
http://localhost:15412/AE/Connector?Connection=Sample%20AP%20Connection&Category=Sample%20AP%20Category&Action=Retrieve%20AP%20Documents&PO%20%23=656
If the actions you have configured in Application Enabler are using the default connection or category, the URL does not need to contain the connection or category, and depending on your configuration could look like this:
http://localhost:15412/AE/Connector?Action=Retrieve%20AP%20Documents&PO%20%23=656
