We have requirement to build an integration with third party. Need to send a record when there is New Hire, Cancel WorkRelationship, Terminate WorkRelationship and Assignment Change(Job and Position). We are building integration in OIC, can we subscribe to multiple Atom Feeds in a single integration? The final output file should have below fields
Person Number, First Name, Last Name, Email Id, Location, Hire Date, Termination Date, Job Code, Position Code, Username

Can anyone give some pointers for this? it will be great help.
