The PayPal Express checkout API has a request parameter for setting a header image to be displayed as part of the checkout flow.
I am currently working on building out the Permissions API, and have noticed that my authentication screen does not display a header image. Browsing through the documentation, I do not see an option for setting this. Could someone please tell me how I can incorporate a header image in the PayPal Permissions API requestPermissions web flow?
Please see a screenshot of the permissions flow I am seeing here: https://i.stack.imgur.com/vrH77.png
Have you tried setting up Custom Payment Pages in your PayPal profile?
