How can I verify that this was installed during our installation. If it was not installed previously, could this be installed after as an add-on?
The Lifecycle API is part of the MyID product and is installed at the same time as MyID itself. There is no means by which to install it as a separate module. If you still wish to verify that it has been installed then you should see the “MyIDEnroll” Application within the IIS Manager on the server hosting the Web components for MyID. For further information about the Lifecycle API please refer to the “Lifecycle API” guide supplied with the standard product documentation.
