Hello,
Something that would really speed up my development would be the inclusion of the app fee within the new Checkout API.
It would save me having to build with the Payments SDK just to make income from my app with the app fee and speed up development because I can make use of the awesome pre-built checkout.
Thought I’d post this in the hope that it gets picked up as a feature.
Thanks,
Phill
This is a very popular feature request and we hope to have more for you soon. 
I am wondering if this is still not an option - I see it still listed in the API explorer but I am getting an error saying not authorized for this location_id and I see that the documentation says it’s not supported with a paylink. AM I reading this wrong or is it NOT supported?
Now app_fee_money is available with the Checkout API payment links. What’s the location_id that you’re getting this error with?
I replied in slack - should I reply in the forums only?
