Hi there,
While you can use Custom Events to integrate any unsupported third party ad networks, we would not be able to assist you with the Amazon setup itself. However, if you can provide us a sample app with Amazon ads built in and if you are looking to integrate it with our Mobile Ads SDK to mediate ads, then we would certainly be able to help you with that.
Do get back to us once you have an Amazon ad sample app setup.
Thanks,
Arjun Busani
