Custom Event vs Filter issue for custom app integration

Hi,

I noticed two different behavior in the invoke Url when the entry point is a Custom Event or a Filter in Responsys. When I use a filter, the records advance the program like a package, so for instance, when these records arrive in the custom app step, Responsys, in a single API call send me the data for all the customers (the scenario is the invocation with data). When I use a custom event, even if in the call there is more than 1 record, once the program arrives in the custom app step, my app receives one invocation call
