Don't worry! It happens sometimes. Transactions can be declined for several reasons. Sometimes you can guess why it was declined from the response code, but only your credit card issuer or financial institution can confirm the specific reason.
The usual culprits are:
- Incorrect credit card number or expiration date
- Insufficient funds
- If you are outside the US, some credit card companies will reject international charges
- The customer's bank or credit card company was having technical issues when the order was processed
- If you made a large number of online purchases within a short period of time, some banks will reject the charges as a fraud prevention measure
If your order is rejected and it happens several times in a row, try clicking the “retry” button again the next day. If there's still no luck, give your financial institution a call.
If your order failed because you didn't add a default payment method to your Printful account, you'll need to add a payment method and confirm the order again. You can add a payment method under Billing > Add Payment Method. You can confirm the failed order after adding a payment method by clicking Orders > Choose order > Confirm.
