During the payment process based on Wirecard Checkout Seamless there are some pages which are managed by the Wirecard Checkout Server. You may customize these pages according to your design requirements.

Customization using CSS

The responsive design of Wirecard Checkout Seamless can be adjusted using a valid CSS file. The URL to this CSS file is stored on your server and must be accessible from the Internet. The CSS file is received via the given URL in the request parameter CssUrl from your server. The rule set contained in the CSS is then used by our responsive design.

Please note that due to security reasons neither url() functions nor @import directives (e.g. external fonts) are allowed in the CSS file. If they are used they will be ignored.
Never send any font changes within the CSS file. Security checks may last several minutes and lead to payment cancelation. We strongly recommend to customize your fonts using CSS templates.

Please download the following zip-file containing the customization templates (MD5 hash 780DAD5521E5329055A82C5AC1F4B8D6).

These templates are also available on GitHub.
