Add `allow="payment"` to whitelisted AdSense Attributes

[ryan-lambert-IEX]

Is your feature request related to a problem? Please describe.
As of Safari 17 (Release Notes), ApplePay is supported within cross-origin iframes with the allow="payment" attribute.

There is no way to add / edit the allow parent googletag iframe attribute. Ideally, publishers could enable this feature and add / edit the allow attribute to enable ApplePay to work within embedded ads.

Describe the solution you'd like
I would like to use the existing set API (e.g., googletag.pubads().set or similar) to add the allow="payment" attribute to the GPT parent iframe. This would require adding this attribute to the whitelsited AdSense Attributes or providing some other way to add / edit the allow attribute to enable this flag.

Describe alternatives you've considered
An alternative would be to allow the allow="payment" attribute to be added serverside.

Additional context
We are an approved Third-Party Ad partner (see list - Dispatch - Digital Asset Communication LLC) and our product is shoppable display ads. It would be a large unlock to the ecosystem to optionally enable ApplePay for our ad format.

Please let me know if there is a better place to make this request.

Thank you.

Hi @ryan-lambert-IEX, thanks for the feedback! Unfortunately this isn't the right support channel for product feature requests. While I will pass your request along to the team, I won't be able to provide any updates here.

If you have an Ad Manager support contact, I recommend reaching out to them about this as well. They will be best equipped to handle this sort of request and keep you updated as things progress.
