Hi @Furnishd,
Sorry if you weren't receiving a response from the email you sent. Glad to see you reach out to the community for information.
If I understand correctly, you are wanting to promote the fact that buyers can sign up for PayPal Credit to make purchases on your site. There isn't a special way to allow PayPal Credit as it works with every merchant that accepts PayPal. If you want to advertise it on your site, here is a place you can grab a banner. Also, here's more information regarding PayPal Credit.
Please let me know if you have any additional questions.
Thanks,
Drew
