# Trigger Anti-Passback via HTTP Command

Akuvox devices support the on-premise and cloud anti-passback feature. It prevents unauthorized access by ensuring that a user cannot enter an area by following others.

Typically, the anti-passback feature is used with Wiegand connections. For non-cloud projects that are unable to connect devices via Wiegand, Akuvox integrates the feature with door opening via HTTP commands.

- The authentication device sends the HTTP URL to the door-opening device, carrying fields of anti-passback mode, unlock type, and code.
- The door-opening device receives the URL, decides whether to open the door, and saves the log.

This article takes A095(the door-opening device) and A01(the authentication device) as examples.

> [!NOTE]
> Compatible models and versions:
> 
> - A095: 95.30.10.110(Only works as the door-opening device)
> - A094: 92.30.10.104(Only works as the door-opening device)
> - A05V2: 205.30.10.157
> - A01/A02: 101.30.10.103
> - A03: 103.30.10.105

## Enable Door-Opening via HTTP

Enable the feature on the A095’s web interface.

1. Use the device IP(scanned by [IP Scanner](/v1/docs/akuvox-ip-scanner)) to log in to its web interface. The initial username and password are **admin**.

2. Go to the **Access Control > Door** interface. Find the **Open Relay via HTTP** section.

3. Enable the feature and customize the authentication username and password.

4. Submit the setting.

## Add Users

Add the same user to both the A095 and A01.

1. Go to the **Directory > User** interface.

2. Click **+Add** to add a user.

3. Enter the username and set up the user’s credentials, such as the RF card.

4. For A095, check the door(s) to be opened and submit the setting.

5. For A01, enter the HTTP URL. You can click **Add** to add up to 10 URLs for more door control.

```plaintext
http://{username}:{password}@{target device IP}/fcgi/OpenDoor?action=OpenDoor&DoorNum={DoorNum}&AntiPassbackMode=$antipassbackmode&Name=$name&UnlockType=$unlocktype&Code=$code
```

For example, http://admin:Admin123@192.168.31.35/fcgi/OpenDoor?action=OpenDoor&DoorNum=1&AntiPassbackMode=$antipassbackmode&Name=$name&UnlockType=$unlocktype&Code=$code

6. Submit the setting.

## Enable Anti-Passback Mode

Set up the feature on the A01’s web interface.

1. On the **Directory > User** interface, select the desired anti-passback mode: **Entry** or **Exit**.

For example, if the user swipes their card to enter the area, then follows someone else out. They cannot swipe their card to enter.

2. Submit the setting.

After configuration, swipe the card on A01, and A095 opens the door.

Swiping the card again on the A01 will fail to open the door.

Check the access log on the **Status > Access Log** interface.
