Acknowledge Events Log Table via API

I would like to acknowledge events in the events log table via the invoke command.   Is this possible?  If not?

How do a get a list of Alerts for a specific node,  I then would like to use that information to pass into a ticketing system.

I already have the form interface, I just need to either know how the Acknowledge the Events in the Events log using the swis or SWQL or get the list of Alerts associated with a node and then Acknowledge them.

Thank you for your help.
