# Trigger Door Actions via HTTP Commands

This guide explains how to trigger door actions on the door phone using HTTP commands from a third-party server.

Supported actions include:

- Door unlock
- Door lock (close)
- Keep the door open
- Get door status
- Deny access

## Compatible Model and Minimum Version

- E18: 18.30.11.27
- R20V5: 320.30.12.28

## Prerequisites

Before proceeding, ensure the following conditions are met:

- The device must be accessible on the same network as your server.
- You have admin access to the device web interface.

This article takes E18 as an example.

## How It Works

Each door action is triggered by sending an HTTP request to the device.

The request must include:

- The device IP address
- Authentication credentials
- The action command
- The door(relay) number

## Step 1: Enable Open Door via HTTP

1. Navigate to the device IP in a browser. The login username and password are **admin**(by default).
2. Go to **Access Control > Relay > Open Relay via HTTP**.
3. Enable the feature.
4. Customize the username and password for authentication.

1. Click Submit.

> [!NOTE]
> Security Recommendation
> 
> Use a unique, strong password for the HTTP relay credentials. Avoid using the default admin credentials.

## Step 2: Check High Security Mode

High Security Mode affects which URL format is accepted. To check the current setting, go to **System > Security > High Security Mode**. It is enabled by default.

- **High Security Mode Switch OFF:** Both the old URL and the new URL are supported.
- **High Security Mode Switch ON:** Only the new URL is supported.

## Step 3: Use the Standard URL Format

Choose the appropriate URL format based on your **High Security Mode** setting. Only the **Action** parameter needs to change between different door commands.

### New URL Format(Recommended)

```plaintext
http://{username}:{password}@{device_ip}/fcgi/OpenDoor?action={Action}&DoorNum={DoorNum}
```

**Example — Open Door**

```plaintext
http://admin:Admin123@192.168.88.118/fcgi/OpenDoor?action=OpenDoor&DoorNum=1
```

### Old URL Format

```plaintext
http://{device_ip}/fcgi/do?action={Action}&UserName={username}&Password={password}&DoorNum={DoorNum}
```

**Example — Open Door**

```plaintext
http://192.168.88.118/fcgi/do?action=OpenDoor&UserName=admin&Password=Admin123&DoorNum=1
```

## Step 4: Replace Parameters

Replace the placeholders in the URL with your actual values:

| Parameter | Description |
| --- | --- |
| `{username}` | The Open Door via HTTP username(set in Step 1) |
| `{password}` | The Open Door via HTTP password(set in Step 1) |
| `{device_ip}` | Device IP address |
| `{Action}` | The action to perform(See **Supported Actions** below) |
| `{DoorNum}` | The relay to be triggered. - Relay A: DoorNum = 1 - Relay B: DoorNum = 2 |

### Supported Actions

| Action | Description |
| --- | --- |
| OpenDoor | Open the door |
| CloseDoor | Close the door |
| OpenDoorForever | Keep the door open |
| DoorStatus | Get door status |
| RefuseOpenDoorWrongCardID | Deny access due to an invalid card |

## Step 5: Examples

The following examples use the new URL format. Replace credentials and IP with your own values.

### Open the Door

```plaintext
http://admin:Admin123@192.168.88.118/fcgi/OpenDoor?action=OpenDoor&DoorNum=1
```

### Close the Door

```plaintext
http://admin:Admin123@192.168.88.118/fcgi/OpenDoor?action=CloseDoor&DoorNum=1
```

### Keep the Door Open

```plaintext
http://admin:Admin123@192.168.88.118/fcgi/OpenDoor?action=OpenDoorForever&DoorNum=1
```

### Get Door Status

```plaintext
http://admin:Admin123@192.168.88.118/fcgi/OpenDoor?action=DoorStatus&DoorNum=1
```

### Deny Access(Invalid Card)

```plaintext
http://admin:Admin123@192.168.88.118/fcgi/OpenDoor?action=RefuseOpenDoorWrongCardID&DoorNum=1
```
