Postbacks - Batched or Event-Driven?

I've recently started using Postbacks to track registrations and first deposits in my own affiliate tracking software. What I have noticed is that, while I expected the postbacks to be event-driven (i.e., when a registration happens, it immediately sends a postback), at least one program 'appears' to be batched.

Is batched the norm and my expectations were simply wrong?

From one program, specifically, I am getting registrations/deposits pretty much on the 11 minute 11 seconds after the hour like this:

Sep 30, 2026, 7:11:12 AM
Sep 30, 2026, 6:11:11 AM
Sep 29, 2026, 4:11:11 PM

So - appears batched to me.

It depends on how you've set it up - most programs allow you to track on events and it depends on the complexity of the program you chose.

Personally, I prefer to use a program that works with QCPA which gievs me the advantage of not having to check every affiliate program individually so I have the ability to have a quick glance at overall qualified conversions. That doesn't mean I don't check the affiliate programs indivdiually but it gives me an overall look at the performance.

The use I get from postbacks is to buy media and be able to see results on a more granular level so I can optimize.
