When you link your Bambora (previously Beanstream), Stripe, Authorize.net or Psigate account with your SilkStart account, you are able to select which types of credit cards you will accept. It is not possible to change these settings for PayPal accounts from within SilkStart.
While logged in as an admin, go to your Admin panel and click on Settings > Payment Settings. You will see the credentials for your payment gateway, and beneath these you will see the logos for various credit cards.
Each payment gateway can process different types of cards - these icons reflect the payment types that your gateway can handle. Your account with your payment gateway may also have restrictions that permit or prevent you from processing certain cards.
Clicking on one of these logos will either show or fade the logo. Faded logos indicate that you will not accept payment by this card type. When you are finished making your choices, click Save.
You may also need to reflect this choice in within your payment gateway's admin tools. If you have any difficulties changing these preferences, contact your payment gateway's support staff.
This organization will only accept payment by Visa and MasterCard - note how the American Express logo is faded out.
