Adding a card to Zendrop triggers an immediate $1 pre-authorization to verify the payment method. It's a quick security check that confirms your card works before it's saved to your account.
Some cards might fail this step if they cannot handle pre-authorization holds.
Pre-authorization process
When you enter your card details into your Zendrop account, Zendrop places a temporary $1 hold on your card to verify it.
Success and card addition
If the pre-authorization is successful, your card gets added to your account. The $1 hold is not an actual charge and releases automatically, usually within a few minutes, depending on your bank's policies.
Typically, this hold is released within a few minutes or hours, depending on your bank's processing time.
Failure and error message
If the pre-authorization fails, you'll see an error and need to provide a valid card.
Common reasons for pre-authorization failure include insufficient funds, unusual or suspicious transactions, failure of 3D Secure authentication, international transaction restrictions, multiple failed attempts, or generic decline errors.
Re-submission
If the $1 hold is unsuccessful, the payment method form will be presented again. You can re-enter your card details or replace your default payment method. General troubleshooting steps include verifying the card details, clearing browser cache or cookies, using a different payment method, waiting before retrying, or contacting your bank for assistance.
If these steps don't resolve it
At that point, the issue is almost always card-level. Contact your bank directly and share the error message. They can clear the block.
Add your payment method from the Billing page and start fulfilling orders.
