# Edit, extend or delete an Access Control booking

Context: Access Control: Edit and Delete actions in the Bookings list, French interface

In Access Control, an active or upcoming booking can be edited: guest address, end of the period, time zone and, as long as it has not started, start date. It can also be deleted. The booked access point itself cannot be changed.

For the signed-in administrator, in the French interface.

## Before you start

- Open **Réservations → Toutes** (Bookings → All) and identify the right row by guest, access point, site and times.
- The **Modifier** (Edit) and **Supprimer** (Delete) actions are not offered for the **expirée** (expired), **révoquée** (revoked) and **annulée** (canceled) states. For a new access, see [Create a booking](https://wiki.can-nx.com/en/guides/ac-create/).

## Edit or extend a booking

1. Select **Modifier** on the booking row. The **Modifier la réservation** (Edit booking) form opens.
2. Adjust the fields you need according to the table below. To extend the booking, move **Au** (To) later. Review the dates and the time zone together.
3. Select **Mettre à jour** (Update) and wait for the return to **Aujourd'hui** (Today).

| Field | Change |
| --- | --- |
| **Email de l'invité** (Guest email) | Possible |
| **Au** | Possible, for example to extend or shorten |
| **Fuseau horaire** (Time zone) | Possible |
| **Du** (From) | Only for an **à venir** (upcoming) booking |
| Access point | Not possible in this form |

A booking that has already started shows **La date de début ne peut plus être modifiée une fois la réservation commencée.** (The start date can no longer be changed once the booking has started.) The duration shortcuts are then no longer offered.

**Annuler** (Cancel) leaves the form before saving. To revert a change afterwards, open **Modifier** again and restore the values if the fields can still be edited. Do not use a time zone change to compensate for a time whose correct period you do not know.

## Delete a booking

1. On the relevant row, select **Supprimer**.
2. Two buttons appear in the same place: **Confirmer** (Confirm) and **Annuler**. **Annuler** closes this confirmation without requesting the deletion.
3. Select **Confirmer** only if you want to remove this booking. After processing, the list reloads.

This screen offers no command to undo a deletion that has already been confirmed, and the same code will not be restored. To grant access again, create a new booking.

## Check the result

- After an edit: find the booking in **Réservations → Toutes** and check the values.
- After a deletion: the booking switches to the **annulée** state. Check it in **Toutes** and **Terminées** (Ended).

## Troubleshooting

If the summary does not match the chosen booking, if the validation does not produce the expected result or if the state remains uncertain, stop making changes. The [Access Control troubleshooting guide](https://wiki.can-nx.com/en/guides/ac-troubleshoot/) details the checks. If doubt remains, contact support@can-nx.com, specifying the operation, the site, the access point and the message displayed, without sending any code.
