I want to generate revenue report based on open ads with custom data. Here, custom data would be the string which uniquely identify my different clients. When ads open from anyone of my client page, I want to pass that uniquely identification to generate report based on that.
I tried many documentations but unable to reach this point. Anyone can guide me on this.
EDIT:
Here's an example showing some ad unit code with the custom channel ID 1234 added to it
