Do I have to pay if my reservation request isn't accepted by the workspace?

No, if your reservation request isn’t accepted by the workspace, there’s no cost for the booking

You may see a temporary authorization or a refunded charge after a reservation request is declined.

If your reservation is accepted, the authorization will turn into a real charge and the amount will be deducted from your payment account.

If the booking request is declined, 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.
