Please revisit your integration and ensure that you are using our approved Android Google Pay Buttons (https://developers.google.com/pay/api/android/guides/brand-guidelines#payment-buttons) or Web Google Pay Buttons (https://developers.google.com/pay/api/web/guides/brand-guidelines#payment-buttons).

All Google Pay payment buttons on your site must adhere to our Android Brand Guidelines (https://developers.google.com/pay/api/android/guides/brand-guidelines) or Web Brand Guidelines (https://developers.google.com/pay/api/web/guides/brand-guidelines), which include, but aren't limited to, the following requirements:
The size must be relative to other similar buttons or elements of the page. You can adjust the button size with the buttonSizeMode option of the createButton API.
The button color must contrast with the background color of the area that surrounds it.
The button must maintain the minimum amount of clear space on all sides of it.
Please make or provide the appropriate updates, and re-submit your integration again through the Google Pay & Wallet Console (https://pay.google.com/business/console).

If the above marketing review feedback cannot be implemented because you are using a dedicated Plugin or provided hosted checkout solution from your Payment Service Provider, please contact us (https://developers.google.com/pay/api/faq#how-to-get-support).
