Important Notes and Caveats


Do not test with real credit cards. We have had reports that CDG shut down an account for testing with live credit cards (and subsequently voiding or refunding the charges). Requests by the merchant to reinstate the account were unsuccessful.

Required Policies for Your Site

In order to obtain a merchant account through CDG, you must have some items for the bank to see. Here's a response from a real application:

Dear Merchant, I know you are still working on your website but the bank needs to see more of your website other than just the place holder page. Here is what the bank will want to see: bank will want to see
* your home page,
* product page with prices and an order button,
* return/refund policy,
* shipping policy,
* privacy policy.
* terms of service
The bank knows the order button will not go to an order page that can process as transaction since you are in the middle of applying for your merchant account. Please email a temp URL. For example: This way, the bank can see what you are working on and what kind of business you have.
