At MetaBox.io, we’re using Gumroad as our main payment processor. It supports paying via both credit cards and Paypal. It’s simple, intuitive and works pretty well for us over the years.

However, some of you might have problem paying with credit card or Paypal via Gumroad. And this page will help you resolve these problems.

My credit card is not accepted

There are various reasons to this problem, please see the following:

1. Browser error

Your browser is interacting with our payment form in a weird way.

Solution: Please try the purchase again in a different browser.

2. The credit card provider is blocking the purchase

Sometimes a bank or provider will flag transactions that happen online (usually for small amounts).

Solution: Please contact your bank/provider and let them know what’s happening. The card provider will be able to “whitelist” Gumroad.

3. Zip code errors

If you are being asked to enter your ZIP or Postal code, that means that your credit card provider is asking you to verify your identity, through the “ZIP” code attached to the card.

Solution: The ZIP Code or Postal code we need is the one stored by your credit card provider. If your are unsure about this, please contact your credit card provider.

I don’t have a credit card

No problem, please switch to Paypal in the payment popup. We do support buying via Paypal.

If you have any other problems, please contact us.
