No - if your booking request isn’t accepted by the host or it has been expired without a response, there’s no cost for the booking request or any BlackDoors service fees.
You may see a temporary authorization or a refunded charge after a reservation request is declined or expires, depending on your payment method.
Temporary authorizations and refunded charges
Before you submit a booking request, you'll see whether your chosen payment method will place a hold (called an authorization) or charge on your account for the amount of the booking.
If your payment method is authorized
Some payment methods require that the full amount of the booking is authorized at the time of your request. If your booking is accepted, the authorization will turn into a charge and the amount will be deducted from your payment account.
If the booking request is declined or expires, you’ll either see the authorization disappear altogether or appear as a refund in your payment account. Depending on the processing time of your bank, the release of the authorization may take up to 7 business days.
