Frequently Asked Question:
Can I accept credit cards through eBay Checkout that are not through PayPal?
Yes, but only if you have a merchant account and a payment gateway service setup on your eBay account. For example, if you have an Authorize.net payment gateway for your merchant account, you can accept credit card payments to your merchant account through eBay Checkout. Refer to eBay for instructions on how to set up your merchant account with their checkout.
Once this is complete, you can indicate which credit card(s) you're willing to accept in the "Checkout Options" section of the lister page.
