When directing to an Amazon Ads site for mobile in-app ads with third-party tags, Amazon Ads requires using a 1×1 pixel and not a redirect.
If you are running creatives served through a third-party on eligible Amazon DSP inventory, you will need to append your third-party tag in the tag source section of creative settings.
All content must be served from the ad server’s domain and may not call from other domains. Only secured calls (https://) are accepted.
Amazon Ads accepts third-party hosted creative libraries from all third-party ad servers.
If a third-party pixel is appended on a creative, and Amazon Ads has a server-to-server integration with that third-party, the creative will not be approved. You will need to remove the pixel, and instead append the adapter URL.
Amazon Ads allows advertisers to run third-party served creatives as long as the ad servers are on the list of approved vendors.
Using invalid macros in creatives will cause the ad to be rejected.
