# Including Authentication Headers in API Calls

If your API target device requires API authentication, an authentication header must be included in the API call.

- For Algo devices using the **Standard**authentication method, the device can automatically generate the **Standard**authentication header to simplify API calls.
- For Algo devices using the **Basic**authentication method, or non-Algo devices or services, the authentication header must be included manually in the **Custom Headers**.

> [!NOTE]
> Note
> 
> Third-party devices or services may use different authentication methods. Refer to their documentation and use the **Custom Headers** field to define the exact HTTP header names and values they require.

### Including Standard Authentication Headers in API Calls to Algo Devices

You can include a standard authentication header in one of the following methods:

- Selecting a preset API command.

Your device automatically includes a **Standard**authentication header.

- Using the **Other** API command type and choosing **Algo Standard Authentication Headers**, so the device automatically includes the standard authentication header.

> [!NOTE]
> Note
> 
> - You must enter the target Algo device’s **RESTful API Password** under **Basic Settings** → **Features**→ **Remote Device Settings** → **Remote Device RESTful API Password**.
> - If your API request targets more than one Algo device, all target devices must use the same **RESTful API Password**.

#### **Setting the Target Algo Device’s RESTful API Password**

To enable automatic generation of **Standard**authentication headers, you must specify the target Algo device’s **RESTful API Password**.

> [!NOTE]
> Note
> 
> If your API request targets more than one Algo device, all target devices must set the same **RESTful API Password**.

**To specify the target Algo Device’s RESTful API Password:**

1. Go to **Basic Settings** → **Features**→ **Remote Device Settings** → **Remote Device RESTful API Password**.

2. Enter the target Algo device’s **RESTful API Password**.

You can set the target Algo device’s **RESTful API Password** in its web interface under **Advanced Settings** → **Admin**→ **API Support**.

### Including Basic Authentication Headers in API Calls to Algo Devices

To include **Basic**authentication headers in API calls to Algo devices, use the **Other API** command type and enter the Basic authentication header in the **Custom Headers** field.

A basic authentication payload requires encoding the username (admin) and **RESTful API Password** using Base64.

You can use online tools such as the [Basic Authentication Header Generator](https://mixedanalytics.com/tools/basic-authentication-generator/) to generate the Base64 header.
