Hi,
The applications that will integrate to this Tool's API will be web
applications, they will set their webservice URL in the configuration of the
API, they may run this API on one of their own servers too. They also have
the facility to poll for the information if they want, so the automation can
be done either way.
Thanks for the replies!
Mark
