Before we create an order for a shopper, we first attempt an authorization on the shopper's card to confirm funds are available.
If that authorization attempt fails or the order creation process fails in your ecom platform and the order is not created, the authorization is immediately cancelled, but may still display on the shopper's bank statement.
If you receive an inquiry from a shopper regarding a pending authorization but there is no order associated with the shopper, you can confirm with them that this was simply an authorization attempt, but because the order failed, the authorization has been cancelled and will drop from their card in 1-3 business days.
